Compare  |  St. Peters, MO Two big three row luxury SUVs with very different personalities, and which one fits the way St. Charles County families drive. Shoppers who end up cross shopping these two usually start in the same place. They need three real rows, they want something nicer than a work truck with leather, and they drive enough highway miles that comfort matters. After that, the Lincoln Navigator and the Jeep Grand Wagoneer head in different directions. We sell the Lincoln Navigator, so read this knowing where we sit. We've tried to be straight about where the Jeep Grand Wagoneer does well, because a buyer who picks the wrong truck for their life isn't a happy customer for either brand. Everything here refers to the 2025 model year unless we say otherwise. Quick answer: Pick the Lincoln Navigator if you want a quiet, lounge style cabin, standard BlueCruise hands free highway driving on the 2025 model, and the Split Gate rear door. Pick the Jeep Grand Wagoneer if you want twin turbo inline six power, serious off road hardware and a premium audio system as part of the deal. Both have three rows and four wheel drive. Both offer Three rows and four wheel drive Lincoln Navigator leans Quiet ride and highway tech Jeep Grand Wagoneer leans Power and off road gear In this post How they differ Ride and power Cabin and technology Space and families Weather and towing Ownership and value How Are the Lincoln Navigator and Jeep Grand Wagoneer Different? On paper they're close. Both are full size, body on frame SUVs with three rows, twin turbocharged engines and four wheel drive. Both come in a standard length and a longer version, the Lincoln Navigator L and the Jeep Grand Wagoneer L, for families that need more room behind the third row. The difference is in what each one was built to put first. The Lincoln Navigator was redesigned for 2025 around calm. The cabin is tuned for quiet, the screens stretch wide and low, and the tech leans into easing a long highway drive. The Jeep Grand Wagoneer puts more weight on muscle and capability, with a twin turbo inline six and 4x4 hardware that comes from Jeep's off road side. Neither approach is wrong. It comes down to which one sounds like your week. Which One Rides and Drives Better on Missouri Highways? On I-70 between St. Peters and Warrenton, the Lincoln Navigator feels like it was made for the trip. It's very quiet at highway speed, quiet enough that reviewers say you can barely hear the engine. The ride soaks up expansion joints and rough patches without much fuss. One reviewer noted the larger optional wheels firm up the ride, so try the wheel size you'd buy. The Lincoln Navigator uses a twin turbocharged V6 with a 10 speed automatic and standard four wheel drive. It moves the size of the vehicle with confidence, though some testers say the transmission can take a beat to downshift when you ask for passing power on a two lane like Highway 79. The Jeep Grand Wagoneer uses Jeep's Hurricane twin turbo inline six with an eight speed automatic, and it's the stronger feeling of the two when you put your foot down. If you like a big SUV that pulls hard up the Highway 364 ramps, that's a point in its favor. Ask our team or a Jeep dealer for current output and towing numbers on the exact trim, since they vary by version and package. It comes down to which one sounds like your week. How Do the Cabins and Technology Compare? The Lincoln Navigator's signature is a 48 inch panoramic display across the dashboard, paired with a center touchscreen running the Lincoln Digital Experience. It looks clean and modern. The trade off is that more functions live in menus, and a few reviewers wish the center screen were bigger for a vehicle this size. The Jeep Grand Wagoneer goes the other way with screen count. Jeep says up to 75 inches of total screen area is available, including a center touchscreen and a standard passenger screen for the 2025 model. A McIntosh audio system is part of the package, and audio fans tend to remember it after a test drive. For highway help, every 2025 Lincoln Navigator comes with BlueCruise hands free driving on approved highways, with four years of service included. The Jeep Grand Wagoneer offers its own Active Driving Assist system. Both are driver assistance, not self driving, and both expect you to keep your eyes on the road. Shop Lincoln Navigator Explore Black Label Which One Works Better for a Big Family? Both handle three rows of people. The Lincoln Navigator offers seating for up to eight depending on configuration, and reviewers like seat comfort in all three rows. The Jeep Grand Wagoneer also seats up to eight in some configurations, with seven as the other layout depending on trim and package. Cargo depends heavily on which length you pick. If you regularly fill the third row and still need room for strollers, hockey bags or luggage, look hard at the Lincoln Navigator L or the Jeep Grand Wagoneer L. The standard length versions of both get tight behind row three. The Lincoln Navigator has one feature that daily family life tends to love. The Split Gate rear door opens the upper glass section like a liftgate, and a lower section folds down like a tailgate you can sit on. It's handy at a soccer field in O'Fallon or a tailgate before a game. Reviewers mention it's harder to reach the base of the third row seatback on the Lincoln Navigator L, so try it with your own gear. The Lincoln Navigator fits you if Most of your miles are highway miles and a quiet cabin matters to you You want hands free highway driving included on the 2025 model The Split Gate sounds useful for sports, tailgates or loading the dog You want Lincoln Black Label ownership perks available on upper trims The Jeep Grand Wagoneer fits you if You want a big six cylinder that pulls hard when you floor it Real off road hardware matters for trails, farm roads or boat ramps A premium McIntosh audio system is high on your list You like a passenger screen so the front seat can run music and maps Which Handles Missouri Weather and Weekend Towing? Both come with four wheel drive, so neither will leave you stuck at the bottom of an icy subdivision hill in Cottleville. The Jeep Grand Wagoneer has the edge if your weekends involve deep mud, a muddy gravel lane to a hunting lease, or a steep wet boat ramp, since its available 4x4 systems include low range hardware built for that. For towing a boat to Lake of the Ozarks or a camper to a state park, both are serious tow vehicles. The Lincoln Navigator offers a Heavy Duty Trailer Tow Package with extra help for long climbs. Ratings vary by length, trim and equipment on both, so compare the exact numbers on the window stickers before you decide. St. Peters driver tip If you're deciding between these two, drive both on the same loop. Take I-70 west to Lake St. Louis for highway noise, then cut down to Highway 94 toward Defiance and the Katy Trail for the curves. Big SUVs feel very different on a winding two lane, and that's where the comparison gets clear. What Does Ownership Look Like for Each One? Service is close to home for both around St. Charles County. With the Lincoln Navigator, owners here get our service drive on North Service Road, Lincoln Mobile Service for many jobs at home or work, and complimentary Pickup and Delivery while the vehicle is inside its 4 year or 50,000 mile new vehicle limited warranty. Upper Lincoln Navigator trims can be ordered as Lincoln Black Label, which adds its own ownership perks. The Jeep Grand Wagoneer has its own dealer network and warranty terms, and you should read them before you buy. Both are expensive vehicles to buy and insure, so compare total cost and incentives along with the window sticker. Our 2026 Lincoln Navigator comparison page lines the Lincoln Navigator up against other full size rivals if you want to keep shopping.

Service  |  St. Peters, MO What the check engine light on a Lincoln is telling you, how to tell a minor issue from a stop now problem, and what a diagnostic visit involves. You're on Highway 364 heading home, and a small amber engine shape lights up on the cluster. The car feels normal. The radio's still playing. Nothing smells hot. Most people's first thought is how long they can ignore it. Sometimes the answer is a few days. Sometimes it's zero miles. We'll go over what that light means on a Lincoln, the difference between steady and flashing, the common causes our technicians see, and what a proper diagnostic does that a parts store code reader can't. Quick answer: A steady check engine light means the engine computer has found a fault and stored a code. It's usually safe to drive gently to an appointment, but book one soon. A flashing light usually means a misfire that can damage the catalytic converter, so ease off, avoid hard acceleration and get the vehicle checked right away. Steady light Book a diagnostic soon Flashing light Ease off and get it checked now Easy first check Is the fuel cap tight In this post What the light means Steady vs flashing Common causes What a diagnostic does Emissions and inspections What to do next What Does the Check Engine Light Mean on a Lincoln? Your Lincoln's engine computer watches dozens of sensors all the time. When one of them reports something outside the range it expects and the problem repeats, the computer stores a diagnostic trouble code and turns on the light. Officially it's called the malfunction indicator lamp, and some owners see a message on the cluster along with it. The light covers a huge range of problems, from a gas cap that didn't click to a misfiring cylinder. That's why guessing gets people in trouble. The light tells you something's wrong. It doesn't tell you what. Is a Flashing Check Engine Light Worse Than a Steady One? Yes, by a lot. A steady light is a heads up. A flashing light usually points to an active misfire, where unburned fuel is going into the exhaust. That fuel can overheat the catalytic converter, and a converter is an expensive part to replace. Flashing light Slow down, skip hard acceleration and get the vehicle checked as soon as you can. If it's shaking badly, pull over somewhere safe and call for help. Light plus rough running Stumbling, shaking at idle or a loss of power along with the light usually means a misfire or fuel delivery problem. Light plus a temperature or oil warning Stop when it's safe. Driving with low oil pressure or an overheating engine can cause damage fast. Light plus a smell A rotten egg smell or the odor of raw fuel points to an exhaust or fuel problem that shouldn't wait. If the light is steady and the vehicle drives normally, you usually have time to book a visit. Don't let it go for weeks, though. Small faults can turn into bigger ones, and while the light's already on, a second problem can't turn it on again to warn you. What Usually Causes a Check Engine Light? The list of possibilities is long. These are the ones that come up most around here: A loose, worn or missing fuel cap, or a capless filler that didn't seal, which sets an evaporative system code. Ignition coil or spark plug faults that cause a misfire. Oxygen sensors or other emissions sensors that have aged out. Vacuum leaks from a cracked hose, which can get worse as rubber shrinks in cold weather. Software that needs an update, which is a fix only a dealer or Lincoln Mobile Service can usually apply. Fall is a common time for the light to show up. The first cold October mornings shrink hoses and seals that were fine all summer. Book a Diagnostic Ask Mobile Service What Happens During a Lincoln Diagnostic Visit? A free code read at a parts store gives you a code number. That's a starting point. A code like P0300 says there's a random misfire, not whether the cause is a coil, a plug, an injector or a vacuum leak. 1 Read the codes and freeze frame The technician pulls stored codes plus the snapshot of conditions when the fault happened, like speed, temperature and load. 2 Check for known fixes Lincoln publishes service information and software updates for some problems. A dealer tech checks those against your VIN. 3 Test the actual part The tech tests the suspect circuit or component to confirm the cause before anything gets replaced. 4 Explain it before fixing it Your advisor walks you through what was found and what it takes to repair, and nothing gets done without your okay. Our service department lists engine diagnostics among its services. Lincoln Mobile Service lists diagnostic scanning and software updates, so some cases can start at your home or office instead of the shop. The light tells you something's wrong. It doesn't tell you what. Will a Check Engine Light Affect a Missouri Emissions Test? St. Charles County is part of the Gateway Vehicle Inspection Program, along with St. Louis City, St. Louis County and Jefferson County. The emissions test reads data from the vehicle's onboard computer, and that same computer runs the check engine light. If your registration renewal is coming up and the light is on, get the cause fixed before you go in. The program's own pages lay out the pass and fail criteria, and an inspection station can tell you how your vehicle would be treated. Clearing the code with a scan tool right before the test usually backfires, because the computer needs a stretch of normal driving to finish its self checks. St. Peters driver tip If the light came on right after you filled up at a station on Mid Rivers Mall Drive, check the fuel cap first. Tighten it until it clicks, then drive normally for a few days. If the cap was the problem, the light often goes off on its own after several trips. If it stays on past that, book a visit. What Should You Do Right After the Light Comes On? Pay attention to how the vehicle feels. Note whether the light is steady or flashing, any other warning with it, and what you were doing when it came on. That helps the technician find the cause faster. Then check the fuel cap, and if everything feels normal, book an appointment within the next few days. If it's flashing or the car's running rough, call us at 636-441-4400 and tell the advisor so they can get you in sooner. You can also see the full list of what our service department handles before you call. Book it your way Use the online scheduler, open the Lincoln app, or call 636-441-4400 and mention the warning light. Inside the 4 year or 50,000 mile new vehicle limited warranty, complimentary Pickup and Delivery brings us your Lincoln and leaves you a Lincoln loaner, and yours comes back washed. Learn About Pickup and Delivery Questions Owners Ask About Driving With the Light On Can I drive to work with the check engine light on? + If it's steady and the car drives normally, usually yes, gently. Book a visit soon. If it's flashing, ease off and get it looked at right away. Can I take a road trip with the light on? + We wouldn't. A long drive with an unknown fault can turn a small repair into a big one. Get it diagnosed before you leave town. Will the light damage anything if I wait? + The light itself won't, but the problem behind it might. A misfire left alone can hurt the catalytic converter, and a sensor fault can affect fuel economy. Questions Owners Ask About Codes and Scanners Can I read the code myself? + Inexpensive scanners can read basic codes. They give you a starting point, but they don't test parts or check Lincoln service information against your VIN. Should I clear the code and see if it comes back? + Clearing it erases the freeze frame data the technician uses to find the cause. Leave it alone unless you've already fixed something simple like the fuel cap. Why did the light go off by itself? + Some faults are intermittent, and the computer turns the light off after several good drive cycles. The code is often still stored, so mention it at your next visit. Questions Owners Ask About Repairs and Coverage Is a check engine light repair covered under warranty? + It depends on the cause and your coverage. Bring the vehicle in, and your advisor can tell you whether the repair falls under the new vehicle limited warranty or another plan. How long does a diagnostic take? + Simple faults can be found quickly. Intermittent ones take longer. Ask your advisor for an estimate when you book. Can a software update fix a check engine light? + Sometimes. Lincoln releases updates for certain issues, and our team checks whether one applies to your vehicle during diagnosis. Questions Owners Ask About Other Warning Lights What color warning lights mean stop now? + Red lights generally mean stop when it's safe, while amber lights mean get it checked soon. Your owner's guide explains each symbol on your model. Is the check engine light the same as a service reminder? + No. A maintenance reminder means scheduled service is due. The check engine light means the computer found a fault. Can cold weather turn on the check engine light? + Cold can expose a weak hose, seal or sensor, so the light sometimes shows up on the first chilly mornings. Cold alone isn't a fault, though, so get it checked. Questions Owners Ask About Getting It Checked Where can I get my check engine light checked in St. Peters? + Our service department at 4760 North Service Road in St. Peters, along I-70. Book online or call 636-441-4400. Can Lincoln Mobile Service scan my car at home? + Diagnostic scanning is on the Lincoln Mobile Service list.

Model  |  St. Peters, MO How the Lincoln Nautilus handles an I-70 commute, a Highway 364 merge and a winter morning, and who should look at something else. Picture a weekday that starts in Lake St. Louis, crawls east on I-70 past the Mid Rivers Mall Drive exit, crosses the river on the Page Avenue bridge and ends in an office park forty minutes later. Then you do it backward. A commute like that tells you more about a vehicle than any spec sheet. We hear questions about the Lincoln Nautilus every week, usually from people who drive some version of that route. So instead of a feature list, this is how the Lincoln Nautilus fits a St. Charles County week, and where it doesn't. Quick answer: For most St. Charles County commuters the Lincoln Nautilus is a strong fit. The 2025 Lincoln Nautilus is a two row midsize SUV with standard all wheel drive, a quiet cabin, a wide panoramic display and an available hybrid. It's a weaker fit if you regularly need a third row or plan to tow heavy loads. Seating Two rows, five seats Drive All wheel drive standard Powertrains Turbo gas or hybrid In this post What the Nautilus is Daily commute Gas or hybrid Weekends and errands Winter and storms Who should skip it What Kind of SUV Is the Lincoln Nautilus? The Lincoln Nautilus sits in the middle of the lineup. It's bigger than the Lincoln Corsair and a lot smaller than the Lincoln Aviator or Lincoln Navigator. Two rows, seating for five, and all wheel drive standard on the 2025 model. The current generation was redesigned for 2024, and the 2025 Lincoln Nautilus mostly carries that design forward. You pick between a turbocharged four cylinder gas engine and a hybrid that pairs the same size engine with electric motors. Both come with all wheel drive. Trims run Premiere, Reserve and Black Label. Inside, the thing everybody notices first is the screen. A panoramic display about 48 inches wide runs across the base of the windshield, with a separate center touchscreen below it. It's a lot of glass, and people tend to love it or need a week to get used to it. How Does the Lincoln Nautilus Handle an I-70 Commute? Quiet is the word owners use most. The Lincoln Nautilus is built to keep road and wind noise down, and on the concrete stretches of I-70 where cheaper SUVs drone, it stays calm enough to take a phone call without raising your voice. The ride leans soft. Expansion joints on the Blanchette Bridge and the patched lanes on the I-70 ramps get rounded off instead of sent up through your back. Some reviewers say the standard drive mode floats a bit over bigger bumps. If you want it tighter, the drive modes let you firm things up. Merging is easy. Both powertrains have plenty of pull for getting onto Highway 364 from a short ramp, and the hybrid adds electric help at low speed, which makes stop and go traffic smoother. The available hands free BlueCruise system can take some of the work out of approved highway stretches. Availability and the included service period depend on the trim and package, so ask the team what a specific vehicle includes. A commute like that tells you more about a vehicle than any spec sheet. Should a Commuter Pick the Lincoln Nautilus Hybrid? If most of your miles are stop and go, the hybrid is worth a serious look. Hybrids earn their keep in traffic, where the electric motors handle more of the low speed driving and the engine gets more time off. That describes a lot of the drive between O'Fallon and the Mid Rivers Mall Drive interchange at 5:15. If your commute is mostly open highway at a steady speed, the gap between the two narrows, and the gas model may make more sense. We'd rather not quote mileage numbers here, because they vary by year, trim and how you drive. Check the window sticker on the exact vehicle and compare. Drive both. The hybrid feels a little different at low speed, and some drivers notice the brake pedal behaves differently than a gas model's. Ten minutes behind the wheel of each will tell you which one you'd rather live with. Shop Lincoln Nautilus See Co-Pilot360 Features Is the Lincoln Nautilus Big Enough for Weekends? For a couple or a family of four, usually yes. The back seat has real room for adults, and the cargo area handles a big grocery run, a pair of golf bags or a weekend of luggage without a fight. The rear seats fold when you need more length. Where it runs out is the bigger stuff. Five people plus a weekend's worth of gear for the lake is tight, and there's no third row for a carpool. If that's your regular Saturday, the Lincoln Aviator is the better fit. Ask for exact cargo and towing figures on the trim you're considering instead of going off a number you read somewhere. They change with the powertrain and options. St. Peters driver tip Take the Lincoln Nautilus out Highway 94 toward Defiance on a test drive. The curves past the Katy Trail crossings show you how it handles when the road stops being straight, and you'll find out quickly whether you like the steering feel. Come back on Highway 364 to try a highway merge. How Does the Lincoln Nautilus Do in Missouri Weather? Standard all wheel drive helps on wet pavement, slush and the occasional icy morning on Salt River Road. It helps you get going and stay settled. It doesn't help you stop any faster, so tires still matter. A good set of all season tires, or winter tires if you want the extra grip, makes more difference come January than anything else. The Co-Pilot360 suite of driver assistance features adds another layer in bad weather, with things like blind spot detection, pre collision assist and lane keeping. Which features are included depends on the trim, so check the window sticker or ask our team for the list on a specific vehicle. In summer, strong air conditioning, plus ventilated front seats on vehicles that have them, earn their keep on a 95 degree afternoon in the office parking lot. Spring hail is another story, and a garage still does more against it than any feature. Who Should Look at a Different Lincoln Instead? If you need seven seats on a regular basis, go look at the Lincoln Aviator. If you tow a boat or a camper to the Lake of the Ozarks every other weekend, the Lincoln Navigator's size and capability make more sense. On the other end, if you're a solo commuter who parks in a tight garage downtown and rarely carries more than one passenger, the smaller Lincoln Corsair may be all you need. You can compare them side by side on our new Lincoln inventory. For the large middle of people who commute, run errands, carry a couple of kids or a couple of friends, and want something comfortable for a Saturday drive, the Lincoln Nautilus is the one we'd point you to first.

Service  |  St. Peters, MO What comes with an oil change at our St. Peters service drive, how often a Lincoln needs one, and what the technician looks at while it's on the lift. Search for an oil change near you in St. Peters and you'll get a long list of quick lube shops along Mid Rivers Mall Drive and Highway 79. Most of them can drain oil and spin on a filter. The difference shows up in what else happens while the car is in the bay, and who's looking at it. This post walks through the oil change package on our service page, the intervals Lincoln recommends, what a technician checks during the visit, and why oil life matters more on the kind of driving most people do around St. Charles County. Quick answer: The oil change package at Dave Sinclair Lincoln St. Peters includes an oil change with synthetic blend oil, a tire rotation and a multi point inspection. For 2008 and newer Lincoln vehicles, Lincoln recommends an oil change every 7,500 miles or every six months, whichever comes first. Package Oil, rotation and inspection Interval 7,500 miles or six months While you wait Lounge with WiFi In this post What's in the package How often to change it The multi point inspection Why a Lincoln service drive Local driving and oil Planning the visit What Does a Lincoln Oil Change Include at Our Store? Our oil change package covers three things in one visit. The technician drains the old oil, replaces the filter and refills with synthetic blend oil. The tires get rotated. Then the vehicle gets a multi point inspection so you leave knowing what's coming up next. Bundling the rotation in saves a second trip. Tires wear unevenly front to rear, and moving them on the same schedule as the oil keeps the wear closer to even across all four. That's one less thing to remember between visits. If your Lincoln calls for a specific oil grade or specification, the team follows what's listed for your engine. Ask your advisor when you check in if you want to see what's going in. How Often Does a Lincoln Need an Oil Change? Our service page lists Lincoln's recommendation by age. For 2008 and newer vehicles, it's every 7,500 miles or every six months, whichever comes first. For 2007 and older vehicles, it's every 5,000 miles or every six months. The six month part catches a lot of people. A Lincoln that mostly goes to the office in O'Fallon and back, or sits in the garage while you take the other car, can hit six months long before it hits 7,500 miles. Oil wears out from time and heat cycles too, and the odometer only tells part of that story. Many newer Lincolns also show an oil life reading or a reminder message on the cluster. Use it, and if it disagrees with the calendar, go with whichever comes up first. Your owner's guide has the exact schedule for your model. What Gets Checked During the Multi Point Inspection? The inspection is where a dealer oil change earns its keep. While the vehicle is on the lift, the technician can see things you'd never spot from the driveway. Here's the kind of ground a typical visit covers: 1 Fluids Levels and condition of the fluids under the hood, so a slow leak or an overdue flush gets flagged early. 2 Tires Tread depth and pressure during the rotation, plus any uneven wear that hints at an alignment or suspension issue. 3 Brakes A look at pad and rotor condition while the wheels are off for the rotation. 4 Belts, hoses and filters Visible cracking, leaks, and the condition of the engine and cabin air filters. 5 Lights and wipers Bulbs that are out and wiper blades that are streaking or torn. You get the results back with each item marked so you can see what's fine, what needs watching, and what needs work now. Nothing gets done beyond the oil change without your approval. Schedule an Oil Change Oil Change Details Why Get a Lincoln Oil Change at a Lincoln Service Department? Our oil change page puts it simply: the right parts, technology and trained certified technicians. The techs here see Lincoln vehicles all day, so they know where each model hides its filter, which ones need software or reminder resets, and what a normal reading looks like on the cars they work on. There's a records angle too. Every visit here goes into your service history at the store. If you ever trade the vehicle in, sell it, or need warranty work, a clean, consistent record helps. Our page also points out that skipping routine maintenance can lead to higher repair costs and reduced value down the road. Oil wears out from time and heat cycles too, and the odometer only tells part of that story. Does St. Charles County Driving Wear Oil Out Faster? It can. Stop and go traffic, short trips, heavy summer heat and towing all put more stress on oil than steady highway miles do. A school run in Cottleville with a stop at Mid Rivers Mall on the way home never gets the engine fully warm. A July afternoon idling in traffic on the Page Avenue bridge runs it hot. Your owner's guide may list a separate schedule for severe conditions. If most of your driving looks like short hops, frequent idling or pulling a boat to Lake of the Ozarks, ask your advisor whether that schedule fits you better. St. Peters driver tip September is a good month to get it done. You're past the worst of the summer heat, and you get a fresh inspection on fluids, tires and wipers before the first cold mornings show up in November. Book an early slot and you can be back on I-70 before the morning traffic thins out. How Do You Plan an Oil Change Visit Around Your Day? Book ahead so the bay is ready when you pull in. Service opens at 7 AM Monday through Friday and 8 AM on Saturday, which makes an early drop off before work easy. If you'd rather wait, the client lounge and business center has complimentary WiFi and refreshments, so you can get some work done. If you can't spare the time at all, Lincoln Mobile Service lists oil and filter changes among the jobs it can handle at your home or office. Check the current service specials before you book, since oil change offers change through the year. Book it your way Pick a time online, book through the Lincoln app, or call 636-441-4400. If your Lincoln is still inside the 4 year or 50,000 mile new vehicle limited warranty, Pickup and Delivery is complimentary: we collect the car, leave a Lincoln loaner, and bring yours back washed. How Pickup and Delivery Works Questions Owners Ask About Oil and Filters What kind of oil goes in my Lincoln? + Our oil change package uses synthetic blend oil, and the team follows the grade and specification listed for your engine. Your owner's guide lists the spec too. Does the filter get replaced every time? + Yes, the oil change service includes a new filter. Running fresh oil through an old filter defeats the purpose. Can I bring my own oil? + Call the service team at 636-441-4400 before you book. They can tell you how they handle customer supplied fluids. Questions Owners Ask About Timing My oil life monitor says 40 percent. Should I wait? + If you're close to six months since the last change, book it anyway. Lincoln's recommendation for 2008 and newer vehicles is 7,500 miles or six months, whichever comes first. What happens if I go way past the interval? + Old oil protects less and can leave deposits behind. Get it changed soon and ask the technician to note anything unusual during the inspection. Is it okay to change the oil early? + Yes. Changing it early does no harm, and it can make sense before a long road trip or after a summer of heavy towing. Questions Owners Ask About the Inspection Do I have to approve any extra work? + Yes. The advisor goes over the inspection results with you, and nothing beyond the oil change gets done unless you say so. Will the inspection find problems before they get expensive? + That's the point of it. Catching worn brakes or a seeping hose during a routine visit usually costs less than waiting for it to fail. Why do you rotate the tires with the oil change? + Front and rear tires wear at different rates. Rotating them at each oil change keeps wear more even and helps the set last longer. Questions Owners Ask About Cost and Specials Are there oil change coupons? + Our oil change page lists several offers. See the current service and parts specials for details, since they change through the year. Is a dealer oil change more expensive than a quick lube? + Our page calls the package very competitive. Compare what's included too, since ours adds the rotation and a full multi point inspection. Does a maintenance plan cover oil changes? + Lincoln maintenance plans can include them. Ask the service team which plan fits your driving and what it covers. Questions Owners Ask About Booking an Oil Change Where is the service department? + Dave Sinclair Lincoln St. Peters is at 4760 North Service Road in St. Peters, along I-70. Service, sales and parts all share 636-441-4400. What are the service hours? + Monday through Thursday 7 AM to 7 PM, Friday 7 AM to 5:30 PM, and Saturday 8 AM to 5 PM. Service is closed Sunday. Can Lincoln Mobile Service change my oil at home? + Oil and filter changes are among the services Lincoln Mobile Service can handle.

Buying  |  St. Peters, MO What a Lincoln courtesy vehicle is, how many miles it carries, what warranty and incentives come with it, and what to check before you sign. Plenty of Lincoln owners have driven one of these without knowing it. When your vehicle stays with our service team for a longer repair, the Lincoln you drive home in the meantime is part of the Lincoln Courtesy Transportation Program. Those loaners don't stay in the fleet for long. After a few months and a few thousand miles they rotate out, and then they're for sale. Shoppers ask about them because they land in an odd spot. They aren't brand new, but they aren't really used in the way most people mean it. Everything below comes from our courtesy vehicle page, plus the questions we'd ask if we were the ones buying. Quick answer: A Lincoln courtesy vehicle is a low mileage Lincoln that served as a loaner or demonstration model in the store's courtesy program. Our page lists them at roughly 1,000 to just over 4,500 miles, with the balance of the New Vehicle Limited Warranty included and eligibility for New Vehicle Retail Incentive Offers plus a courtesy discount. Typical miles 1,000 to just over 4,500 Warranty Balance of new vehicle coverage Pricing Courtesy discount plus incentives In this post What a courtesy vehicle is How many miles Warranty and discounts Who it fits What to check first Finding the right one What Is a Lincoln Courtesy Transportation Vehicle? The store runs a luxury loaner fleet for service customers. Those vehicles also get used as demonstration models, so a shopper might take one out on a test drive while a service guest uses another one for a few days. Once a vehicle has done its time in that fleet, it's taken out of rotation and sold. Our service department maintains every one of them while they're in the program. That matters more than it sounds. A loaner gets its oil changes and checks on our schedule, by the same certified staff who work on customer cars, instead of whenever a previous owner got around to it. The program carries the name Lincoln Courtesy Transportation Program, and you'll see LCTP on paperwork and listings. Same thing. How Many Miles Do Lincoln Courtesy Vehicles Have? Our page puts them at about 1,000 miles up to just over 4,500. Most new vehicle shoppers would never notice that kind of mileage on a test drive. The interior still smells new, the tires have nearly all their tread, and the odometer hasn't seen a full season of commuting. There are also minimum in service rules a courtesy vehicle has to meet before it qualifies for the full advertised discount. The page lists two ways a vehicle gets there: Time first: three months, or 90 days, in service with at least 1,000 miles of customer driven LCTP mileage. Miles first: 3,000 miles of customer driven LCTP mileage and at least 30 days in service. So a courtesy vehicle with 1,200 miles on it may have spent three months in the fleet, and one with 3,000 miles may have been out a little over a month. Neither one is better by default. Ask which path a vehicle took, and you'll know how long it sat in the program and how hard it was driven. What Warranty and Discounts Come With a Courtesy Vehicle? At the time of purchase, the balance of the New Vehicle Limited Warranty comes with it. You aren't buying an expired or partial plan. You're picking up the same factory coverage, minus whatever time and miles the vehicle used while it was a loaner. On pricing, our page says courtesy vehicles qualify for New Vehicle Retail Incentive Offers and a courtesy discount. They're also eligible for Lincoln factory direct incentives, our A/X/Z plan, and additional rebates. The incentives change through the year, so check the current Lincoln offers and ask which ones apply to the vehicle you're looking at. That combination is the reason people seek these out. A courtesy vehicle prices like a discounted new Lincoln and still carries most of its new warranty. See Courtesy Vehicles Get Pre Approved Who Is a Courtesy Vehicle a Good Fit For? The shoppers who get the most out of one usually want a current Lincoln and don't care about being the first person in the driver's seat. If a few thousand miles don't bother you, a courtesy vehicle lets you put the discount toward the trim or package you wanted in the first place. It's less of a fit if you want to order a specific color and option list from the factory, or if you're set on a vehicle with zero miles. The fleet is whatever happens to rotate out, so the selection moves around from month to month. What Should You Check Before Buying a Courtesy Vehicle? Most of this applies to any low mileage vehicle. A couple of points are specific to courtesy units. 1 Confirm the exact mileage Read the odometer yourself and compare it to the listing. Inventory photos and numbers can lag behind a vehicle that's still in use. 2 Ask how much warranty is left Ask the sales team to show you the remaining New Vehicle Limited Warranty coverage by time and by miles, in writing, for that specific VIN. 3 Check trim and options in person Our page notes the vehicle shown may not represent the actual vehicle, and options, colors, trim and body style may vary. Sit in the one you'd buy. 4 Ask which incentives apply Retail offers, the courtesy discount, rebates and plan pricing can stack differently. Ask for each line to be listed. St. Peters driver tip Give a courtesy vehicle the same test drive you'd give a new one. Pull out of the lot onto North Service Road, get on I-70 for a couple of exits to hear it at highway speed, then come back through Mid Rivers Mall Drive and Mexico Road for the stop and go. Twenty minutes tells you a lot. How Do You Find the Right Courtesy Vehicle? Start on our courtesy vehicle page and filter for the model you want. All vehicles are subject to prior sale, and these go one at a time, so if you see one you like, call or stop in rather than waiting for the weekend. Some listings carry a double dagger symbol. Those vehicles aren't in inventory today but may be available at the dealership within one week of your request. If the model you want isn't showing, tell the sales team what you're after and they can watch for the next one rotating out of the fleet. A courtesy vehicle prices like a discounted new Lincoln and still carries most of its new warranty. Warranty Forever on qualifying vehicles Warranty Forever adds lifetime powertrain coverage on qualifying new and pre owned vehicles for as long as you own them, with no deductible. Ask the team whether the courtesy vehicle you like qualifies. How Warranty Forever Works Questions Owners Ask About Courtesy Vehicle History Who drove a courtesy vehicle before me? + Service customers who needed a loaner while their own Lincoln was in the shop, plus shoppers on demonstration drives. The miles on it are customer driven LCTP miles, which is how the program tracks them. Was the courtesy vehicle serviced while it was a loaner? + Yes. Our page says our certified service staff maintains all Lincoln Courtesy Transportation Program vehicles while they're in the fleet. Is a courtesy vehicle the same as a demo? + They overlap. Our page describes them as vehicles previously used as loaner and demonstration models, so one vehicle may have done both jobs. Questions Owners Ask About Courtesy Vehicle Warranty Does the factory warranty transfer to me? + The balance of the New Vehicle Limited Warranty is included at the time of purchase. Ask the sales team to confirm the remaining time and miles for the exact vehicle. Can I add Warranty Forever to a courtesy vehicle? + Warranty Forever applies to qualifying vehicles, and the rules are in the agreement. Ask the team whether a specific courtesy vehicle qualifies before you sign. Do I need to service it here to keep the warranty? + The factory warranty has its own terms in the warranty guide. Warranty Forever has separate maintenance rules, so read both and ask if anything's unclear. Questions Owners Ask About Courtesy Vehicle Pricing Why do some courtesy vehicles show a bigger discount than others? + A vehicle has to meet the minimum in service requirements to get the full advertised discount. One that hasn't hit 90 days or 3,000 miles yet may price differently. Can I use X Plan pricing on a courtesy vehicle? + Our page says courtesy vehicles are eligible for our A/X/Z plan. Eligibility for the plan itself depends on Lincoln's partner rules, so bring your PIN and proof of eligibility. Do Lincoln rebates apply to courtesy vehicles? + The page says they're eligible for Lincoln factory direct incentives and additional rebates. Offers change, so ask which ones are active on the day you buy. Questions Owners Ask About Paying for One Can I finance or lease a courtesy vehicle? + Talk to our Finance Department about the options on the vehicle you choose. You can get pre approved online before you come in. Can I trade in my current car toward a courtesy vehicle? + Yes, trades work the same way they do on any purchase. Getting your trade value first makes the numbers easier to compare. Are taxes and fees included in the listed price? + No. Our page says listed prices exclude tax, title and license charges. Questions Owners Ask About Shopping in St. Peters Can I put a hold on a courtesy vehicle? + All vehicles are subject to prior sale. Call 636-441-4400 and ask the sales team what they can do for the specific vehicle. What are the sales hours? + Sales is open Monday through Friday 9 AM to 7 PM and Saturday 9 AM to 5:30 PM at 4760 North Service Road in St. Peters. How often do new courtesy vehicles show up? + It depends on how quickly loaners hit their time or mileage. Tell the team the model and trim you want, and they can let you know when one comes out of the fleet. Know Your Trade Value First Get a number on your current car before you shop.

Service  |  St. Peters, MO Which Lincoln jobs a technician can handle in your driveway or office lot, which ones still need the shop, and how to set up a visit. Plenty of Lincoln owners in St. Charles County never come out to North Service Road for routine work anymore. The technician comes to them. A van shows up in the driveway in O'Fallon or the parking lot of an office park off Mid Rivers Mall Drive, the work gets done, and the owner never leaves the kitchen table or the conference room. That's Lincoln Mobile Service. It covers a longer list of jobs than most people expect, and it has some limits worth knowing before you book. We'll go through what it handles, how a visit goes, what to have ready, and when you're better off bringing the car to us. Quick answer: Lincoln Mobile Service sends a technician to your home or office for jobs like oil and filter changes, batteries, tire rotations, wiper blades, fluids and filters, bulbs, software updates, diagnostic scans and recall work. Bigger repairs still happen in the shop. Call 636-441-4400 or use the Lincoln app to see if your job and location fit a mobile visit. Where it happens Your home or office Good fit Routine maintenance and recalls Still needs the shop Bigger repairs In this post What mobile service is What it covers How a visit goes Getting ready Mobile or the shop What Is Lincoln Mobile Service? Lincoln describes it as automotive service performed at the location you pick, at the time you prefer. In practice, a trained technician brings tools, parts and equipment in a service vehicle and does the work where your Lincoln is already parked. You hand over the key, go about your day, and get it back when the job's finished. It isn't a full shop on wheels. Lifts, alignment machines and heavy diagnostic equipment stay at the dealership. What it does well is the steady stream of routine work that keeps a Lincoln healthy, the jobs that used to cost owners a morning in a waiting room. Which Services Can Be Done at Your Home or Office? The Lincoln Mobile Service list is longer than people guess. It includes: Oil and filter changes, plus other fluids and filters Battery testing and replacement Tire rotation, and tire repair or replacement when properly equipped Wiper blade replacement, lamps and bulbs Diagnostic scanning and software updates Field service actions and recalls Accessory installs, windshield chip repair and brake services Collision is on the published list too, which usually means smaller jobs, since serious body work needs our Body Shop and Collision Center. Not every job is available every day or at every address. When you book, tell us exactly what you need and where the car will be, and we'll confirm whether a mobile visit fits. Recalls are one of the handiest uses. Many recall fixes are software updates or quick part swaps, and getting one done in your driveway means you aren't putting it off for months. How Does a Mobile Service Visit Work? 1 Book it Call 636-441-4400 or schedule through the Lincoln app. Tell us the job, your address and the window that works. 2 Get confirmation We confirm the job is a mobile fit and that the right parts will be on the van. 3 The technician arrives They check in with you, look over the vehicle and talk through anything they notice. 4 Work gets done on site Most routine jobs are finished while you're working or home doing something else. 5 Wrap up You get a rundown of what was done and anything the technician recommends for a later visit. Ask about cost and eligibility when you book. The mobile service page doesn't list fees or who qualifies, so we'd rather give you a straight answer on the phone than guess here. Schedule Service Book in the Lincoln App What Should You Have Ready Before the Technician Arrives? A little setup makes the visit go faster. Park on a flat, firm surface with room to open the doors and the hood. A level driveway works. A steep slope or a soft gravel shoulder doesn't. If you live in an HOA neighborhood or the visit is at an office, check the parking rules first so nobody gets a note on the windshield. Leave the key where you agreed, or meet the technician. Clear out the cargo area if the job involves tires or a spare. If a warning light or noise has been bothering you, write it down and mention it. A detail like when it happens can save a lot of time. St. Peters driver tip Mobile visits work great in the summer if you plan for shade. A technician working on a black Lincoln Navigator in a full sun driveway in Cottleville at 2 PM in August is working in an oven. If you can, book a morning slot or leave the car in the shade of the house. It isn't a full shop on wheels. When Should You Bring Your Lincoln to the Shop Instead? Anything that needs a lift, a long diagnosis or heavy equipment belongs in our service bays. That includes most transmission work, suspension repairs, alignments, serious collision damage, cooling system repairs and hard to find electrical problems. If you aren't sure, call and describe the problem. We'll tell you which way makes sense. There's also a middle option. If your Lincoln is within the 4 year or 50,000 mile new vehicle limited warranty, Pickup and Delivery is complimentary. We pick the car up, leave a Lincoln loaner, do the work in the shop and return it washed. You get the shop's full capability without driving out to St. Peters. Book it your way Ask for a mobile visit, a shop appointment or Pickup and Delivery online, in the Lincoln app, or at 636-441-4400. Pickup and Delivery comes at no charge for vehicles inside the 4 year or 50,000 mile new vehicle limited warranty, with a Lincoln loaner while we have yours. Read About Pickup and Delivery Questions Owners Ask About Mobile Visits Do I have to be home for a mobile service visit? + Not always. Many owners leave the key in an agreed spot. Talk it through when you book so the technician knows what to expect. Can a mobile visit happen at my office? + Yes, as long as the vehicle is parked somewhere safe for the work and the lot allows it. Check with building management first. What happens if it rains during my appointment? + Some jobs can go ahead in light rain and some can't. We'll contact you if the weather means moving the visit. Questions Owners Ask About What Mobile Covers Can I get an oil change through Lincoln Mobile Service? + Yes. Oil and filter changes are among the jobs mobile service can do at your location. Can mobile service handle a recall? + Recalls and field service actions are on the mobile service list. Give us your VIN when you book so we can confirm the parts are ready. Can a technician replace my tires at home? + Tire repair and replacement are offered when the mobile unit is properly equipped. Call ahead so we can check for your tire size and job. Questions Owners Ask About Scheduling How far ahead should I book a mobile visit? + Book as early as you can, especially before holidays. Openings depend on the day and the area. Can I book mobile service in the Lincoln app? + Yes. You can schedule service through the Lincoln app, or call 636-441-4400. Does mobile service come to Lake Saint Louis and Cottleville? + Service areas can change, so give us your address when you book and we'll confirm coverage. Questions Owners Ask About Cost and Coverage Is Lincoln Mobile Service free? + The mobile service page doesn't list costs, and they can depend on the job and the vehicle.

Compare  |  St. Peters, MO Two compact luxury SUVs that both fit a garage in O'Fallon, and two very different ideas of what the drive to work should feel like. A lot of people shopping compact luxury SUVs in St. Charles County have one main job for the vehicle. It's the daily run down I-70 or across Highway 364, five days a week, with a Costco trip and a weekend at the lake mixed in. If that's you, the Lincoln Corsair and the Audi Q5 are both reasonable picks, and they go about it in very different ways. Audi just rolled out a new generation Audi Q5 this spring, so plenty of shoppers are curious. We sell the Lincoln Corsair and we're glad to say why we like it. We'll also tell you where the Audi Q5 has the edge, because the right answer depends on how you drive. Quick answer: Choose the Lincoln Corsair if you want a soft, quiet ride, a relaxed cabin and the option of a plug in hybrid for short local trips on electric power. Choose the Audi Q5 if you want a firmer, sportier drive, standard all wheel drive and a high tech screen layout. Drive both on your real commute before you decide. Lincoln Corsair strength Quiet, comfortable ride Audi Q5 strength Sporty, planted feel Plug in hybrid Lincoln Corsair Grand Touring In this post How they compare The daily commute The plug in hybrid Inside the cabin Which one fits you How Are the Lincoln Corsair and Audi Q5 Different? The 2025 Lincoln Corsair comes two ways. The Premiere and Reserve use a turbocharged four cylinder, with front wheel drive standard and all wheel drive available. The Lincoln Corsair Grand Touring is a plug in hybrid with all wheel drive, so it can cover a lot of short trips on electric power if you charge at home. The new Audi Q5 that reached dealers this spring is a full redesign. The standard engine is a turbocharged four cylinder with a quick shifting dual clutch transmission, and quattro all wheel drive comes on every one. The Audi SQ5 adds a V6 for buyers who want more. There's also a sloped roof Audi Q5 Sportback for people who care more about style than rear headroom. So on paper, they're close in size and purpose. Behind the wheel, they feel like they were built for two different drivers. Which One Is Easier to Live With on I-70 Every Day? Commuting from St. Peters, you deal with stop and go traffic near the Mid Rivers Mall Drive interchange, long stretches at highway speed, and plenty of patched pavement. The Lincoln Corsair is tuned for that. The ride is soft, the cabin stays hushed, and the seats are set up for comfort over an hour in the car. It's the kind of vehicle you get out of at the end of the day without feeling worn out. The Audi Q5 feels tighter and more connected. Steering is more precise, the body stays flatter in a curve, and it feels at home on the ramps where Highway 364 meets I-270. The tradeoff is a firmer ride, and on rough pavement you'll feel more of the road. Drivers who like a sport sedan tend to love it. Neither of those is a flaw. It's a question of what you want your 25 minutes each way to feel like. See the Lincoln Corsair Current Lincoln Offers Does a Plug In Hybrid Make Sense for a St. Charles County Driver? For some people, yes. The Lincoln Corsair Grand Touring can run on electric power for shorter trips, then switch to the gas engine when the battery runs low. If your days are mostly errands around St. Peters and O'Fallon, school pickup and evening practice at Quail Ridge Park, you could do a lot of that without burning gas, especially if you can plug in at home overnight. It makes less sense if you drive long highway miles every day or can't charge at home. You'd still get the all wheel drive and the hybrid's smooth pull, but you'd use more gas. Ask us for the electric range figures on the window sticker of the specific vehicle, since that's the number that counts for your routine. The new generation Audi Q5 launched here with gas engines only. If a plug in hybrid is high on your list, the Lincoln Corsair Grand Touring is the one in this pair that offers it today. It's a question of what you want your 25 minutes each way to feel like. How Do the Cabins and Tech Compare? The new Audi Q5 makes a statement inside. A wide curved display combines the gauges and a big touchscreen, and you can add a separate screen for the front passenger. If you love tech, it's impressive. If you prefer simple controls, give yourself some time with it before you buy. The Lincoln Corsair takes a calmer approach. The cabin is quiet and comfortable, with an easy layout that doesn't take long to learn. It feels more like a living room than a cockpit, and a lot of our customers say that's the point. Driver assist features vary by trim on both vehicles, so check the window sticker on the specific one you're looking at. St. Peters driver tip Test drive at the time of day you commute. A 7:30 AM run east on I-70 from Mid Rivers Mall Drive to the Highway 94 exit and back tells you more about ride and road noise than a quiet Sunday loop. Bring the coffee mug and the work bag and see where they go. Which One Should You Choose? We'd sort it like this after a test drive in each. The Lincoln Corsair fits you if Your commute is mostly I-70 and Highway 364 and you want it quiet You like a soft, comfortable ride over a sporty one You'd use a plug in hybrid for short local trips You want simple, easy controls You want to buy and service at one St. Peters store The Audi Q5 fits you if You want a firm, sporty feel and sharp steering You want all wheel drive standard on every trim You love big, high tech screens You'd consider the sloped Audi Q5 Sportback roofline A firmer ride on rough pavement doesn't bother you If you can't decide, drive the Audi Q5 first and then come drive the Lincoln Corsair the same afternoon. Fresh memory makes the choice easier.

Service  |  St. Peters, MO What makes an engine run hot in a Missouri July, the early signs owners miss, and the right move if the warning comes on in traffic. Picture the Blanchette Bridge at five on a Friday in July. It's 96 degrees, the traffic is crawling east, and the AC is running flat out. Under the hood, your engine is making a lot of heat and getting very little air to carry it away. That's the exact moment a cooling system with a small problem stops keeping up. Overheating is one of the few car problems where a few minutes can turn a modest repair into a major one. The good news is that cooling systems usually show signs well before they fail. We'll cover why summer is the risky season, what to watch for, what to do if the warning comes on, and what our technicians check. Quick answer: If your Lincoln shows a high temperature warning, smells sweet like syrup, leaves green, orange or pink drips, or the coolant level keeps dropping, have the cooling system checked soon. If it overheats while driving, turn off the AC, pull over safely, shut the engine off and don't open the coolant cap while it's hot. Riskiest moment Stop and go heat Early clue Coolant level dropping Never do this Open a hot cap In this post Why July is risky Warning signs If it overheats What we check Preventing an overheat Why Do Engines Overheat More in a Missouri Summer? The cooling system moves heat from the engine to the outside air. Coolant runs through the engine, picks up heat, and flows to the radiator up front, where air passing through the fins cools it off. A water pump keeps it moving, a thermostat decides when it flows, and electric fans pull air through when you aren't going fast enough to do it yourself. Hot days shrink the margin. When it's 95 outside, the air passing through the radiator is already warm, so it can't carry as much heat away. Add stop and go traffic, a full car, a hill or a trailer, and the AC condenser dumping its own heat in front of the radiator. A system that's fine in April can come up short on a July afternoon. Most of the time the cause is ordinary. Coolant gets low from a slow leak, a fan stops working, a thermostat sticks, or an aging pump stops moving enough fluid. Catching it early keeps it ordinary. What Are the Early Signs of a Cooling System Problem? These usually show up days or weeks before a real overheat. Take any of them seriously in summer. Temperature warning or a high gauge A message on the cluster, or a gauge reading higher than it normally does in traffic. A sweet smell Coolant has a syrupy smell. Noticing it around the car or through the vents often means a leak. Colored drips Green, orange or pink spots under the front of the car. Coolant colors vary by type. Coolant level keeps dropping If you've added coolant once and it's low again, it's going somewhere. Steam or a hiss Steam from under the hood or a hissing sound after you park. Stay back and don't open the hood right away. Coolant is toxic and tastes sweet to pets. If you see a puddle in the garage, clean it up quickly and keep dogs and cats away from it. What Should You Do If Your Lincoln Overheats? Stay calm and act quickly. Driving on with an overheated engine is how a hose replacement becomes an engine replacement. 1 Turn off the AC That takes some load off the engine and stops the condenser from adding heat in front of the radiator. 2 Get off the road safely Signal, move to a safe spot well off traffic, and put the hazards on. 3 Shut the engine off Let it sit. Don't open the hood until the steam stops, and keep your hands away from the engine. 4 Leave the cap alone The system is under pressure when it's hot. Opening the cap can spray scalding coolant. Wait until it's fully cool. 5 Call for help Call roadside assistance or call us at 636-441-4400. We'll help you decide whether it's safe to drive or needs a tow. Driving on with an overheated engine is how a hose replacement becomes an engine replacement. Schedule a Cooling System Check See Service Specials What Does a Lincoln Cooling System Check Include? Our service department lists cooling system and radiator repair among its services, and a good diagnosis starts by finding out where the heat or the coolant is going. Your technician will usually look at: Coolant level and condition, and whether the right type is in the system A pressure test to find leaks at hoses, the radiator, the water pump and the reservoir Cooling fan operation at idle and with the AC on Thermostat behavior as the engine warms up Belts and hoses for cracks, soft spots and wear Any stored codes that point to a sensor or temperature problem Lincolns use a specific coolant, and the type can differ by model and year. Mixing the wrong kind can cause problems down the road, so ask us before you add anything other than what your owner's guide calls for. If the check finds a failing part, your advisor will explain what and why before any repair starts. St. Peters driver tip On a hot day, glance at the temperature reading when you're stuck on Mid Rivers Mall Drive near the mall or on the Page Avenue bridge. Those slow crawls are where a weak fan shows itself first. If the reading creeps up in traffic and drops once you're moving again, book a check before the next heat wave. How Can You Prevent an Overheat This Summer? Check the coolant reservoir once a month with the engine cold. It has marks for minimum and maximum. If the level is under the line, add the correct coolant and keep an eye on it. If it drops again, bring it in. Follow the coolant service interval in your owner's guide. Old coolant loses its ability to protect against corrosion, and corrosion is what eats radiators and water pumps from the inside. Keep the front of the car clear of leaves, bugs and grime so air can get through. Mention a hot gauge or a sweet smell at any visit. Our technicians can look at the cooling system when your Lincoln is in for an oil change or other work, and it often takes only a few minutes to spot a weeping hose. Book it your way Book online, use the Lincoln app, or call 636-441-4400 to set up a cooling system check. For Lincolns still under the 4 year or 50,000 mile new vehicle limited warranty, we offer complimentary Pickup and Delivery with a Lincoln loaner, and your vehicle comes back washed. Request Pickup and Delivery Questions Owners Ask About Coolant Can I add water instead of coolant in an emergency? + In a true emergency, water can get you to a safe place, but it dilutes protection and the system should be checked and refilled with the correct coolant soon after. How often should Lincoln coolant be changed? + Follow the interval in your owner's guide, since it varies by model and year. Your advisor can look it up by VIN. Why does my coolant look rusty or murky? + Old coolant can break down and pick up rust or debris. That's a sign it's past due, and a technician should look at it before you add more. Questions Owners Ask About Overheating Is it safe to drive a little if the engine is running hot? + Short, slow driving to a safe spot is the most we'd suggest. Pushing an overheated engine can warp parts and cause a much bigger repair. Why does my Lincoln run hotter with the AC on? + The AC condenser sits in front of the radiator and adds heat there. A healthy system handles it, but a weak fan or low coolant shows up first with the AC running. Can a bad thermostat cause overheating? + Yes. A thermostat stuck closed keeps coolant from reaching the radiator. A stuck open thermostat usually causes the opposite problem, a slow warmup. Questions Owners Ask About Leaks How do I know if a puddle is coolant? + Coolant is usually green, orange or pink, feels slick and smells sweet. Clear water near the front passenger side is often AC condensation, which is normal. Can a small coolant leak wait until my next oil change? + In summer, we wouldn't let it wait long. Small leaks grow, and losing coolant in hot traffic is how overheats happen. Will a leak sealer from the parts store fix it? + We'd avoid it. Sealers can clog passages in the radiator and heater core. Finding and fixing the leak is the safer move. Questions Owners Ask About Fans and Pumps Should my cooling fan run after I turn the car off? + On many vehicles, yes. The fan may keep running briefly to cool the engine after a hot drive. It should shut off on its own. What are the signs of a failing water pump? + Leaking coolant near the front of the engine, a whining or grinding sound, or a rising temperature reading can all point to the pump. Can a weak battery affect the cooling fans? + Electric fans need steady power. A charging problem can cause odd electrical behavior, so our battery service team can test the battery and charging system during the same visit. Questions Owners Ask About Service in St. Peters Where can I get a cooling system check in St. Peters? + Dave Sinclair Lincoln St. Peters is at 4760 North Service Road, along I-70. Book online or call 636-441-4400. Can you look at my car if it was towed in? + Yes. Call us so we know it's coming, and tell us what happened before it stopped. That helps the technician start in the right place. Is cooling system work covered under warranty? + It depends on your Lincoln's age, mileage and the part. Your advisor can check coverage by VIN before any work starts. Stay Ahead of the Heat A quick check now costs less than a tow later.
