People near Belleville Illinois often ask Stock's Underhood Specialists Inc. how often they should have a particular service done. It's a great thing to ask. You can look at your owner's manual, or have your Belleville Illinois service advisor at Stock's Underhood Specialists Inc. look up your vehicle in a service database. What you find is often a surprise to people – there are actually two service schedules.
One is the regular schedule and the other is the severe service schedule. Service intervals are shorter on the severe service schedule. When asked, most folks in Belleville Illinois will say that their driving is normal and that the 'regular' schedule probably applies to them. 'Severe service' sounds pretty extreme – 'I don't drive like that'.
Well, here is what the manufacturers say constitutes severe driving conditions; you can draw your own conclusions.
- Most of your trips are less than four miles.
- Most of your trips are less than ten miles and outside temperatures are below freezing.
- The engine is at low speed most of the time – not on the highway. You operate your vehicle in dusty areas.
- You regularly tow a trailer or carry heavy loads.
- Drive with a car-top carrier.
- Stop and go driving.
- Driving in very hot or very cold weather.
If that's severe driving, what constitutes regular driving? Well, it would look something like this: I live somewhere with moderate temperatures all year round – I'm thinking San Diego here. And I live close to a freeway on-ramp. Everywhere I need to go is right off the freeway, at least four miles from my home. I can drive at a steady 60 miles per hour when I'm on the freeway.
I don't know about you, but that doesn't sound like my normal driving. It sounds more like ideal conditions. I live where it gets hot in the summer and cold in the winter. I run short errands around Belleville. Occasionally we load up for family trips.
For me, normal driving includes elements of severe service driving. So here's what I tell people: think about how you drive, where you live, where you go and what you are expecting to with your vehicle in the near future.
Picture a line with 'regular' on one end and 'severe' on the other, and make a judgment on where you fall. If your regular oil change recommendation is 5,000 miles and the severe service recommendation is 3,000 – when should you change your oil? For me, it's closer to 3,000 miles. For my wife, it's closer to 5,000 miles. Your Belleville Illinois auto service advisor at Stock's Underhood Specialists Inc. will be happy to have this discussion with you and help you sort it out.
Just a quick word on why severe service intervals are shorter. One has to do with heat. That can either be external heat from the weather or engine and transmission heat from stop and go driving or working extra hard moving heavy loads or towing. The heat causes the fluids like oil and transmission fluid to break down more quickly and then they aren't as effective.
Another factor is water. Moisture naturally collects in fluids as they cool. In your motor oil, for example, if you don't drive long enough for the oil to fully heat up, the water won't evaporate. Water in the oil can lead to the buildup of damaging sludge.
If you live where the air is dusty or polluted, fluids will become contaminated and filters will get dirtier more quickly.
So make an honest evaluation of your driving conditions. You've made the commitment to take care of your vehicles, so it only makes sense to follow the right schedule.
Don't you hate it when you hear that squeal from under the hood when you're zipping down a busy Belleville expressway? It usually means there is a problem with the serpentine belt. The serpentine belt powers a lot of engine accessories. It runs the alternator - which charges the battery; the water pump - which cools the engine; the air conditioning and the power steering pump. All pretty essential parts. It is called a serpentine belt because it snakes around a bunch of engine components.
Serpentine belts are amazingly tough. They can last for years and go for tens of thousands of miles. Like all vital moving parts, however, they eventually wear out. If your belt breaks while you are driving around Belleville, everything will come to a halt within minutes. You need to stop the Sedan immediately or it will overheat, potentially causing pricey engine damage. You can be sure that it won't happen at a convenient time or place. (As if there was a convenient time or place!) You might even need to get your Sedan towed to Stock's Underhood Specialists Inc.. It's no wonder that auto manufacturers recommend a belt replacement on schedule. It's one of those "have-to's."
Belleville car owners who hear a squeal when accelerating or a slow, slapping sound at idle, should have their serpentine belt looked at. Your service specialist at Stock's Underhood Specialists Inc. in Belleville will visually inspect your belt to see if it needs to be changed sooner than scheduled. If the belt has more than three or four cracks an inch, has deep cracks that penetrate half the depth of the belt, is frayed, is missing pieces or has a shiny glazed look, it needs to be replaced regardless of age or mileage.
Serpentine belt replacement is relatively inexpensive, especially compared with the cost and inconvenience of being stranded or getting a disabled Sedan back to Stock's Underhood Specialists Inc. for vital repairs.
You're mom was right: an ounce of prevention really is worth a pound of cure.

Most Illinois car owners know that their vehicles need regular preventive maintenance like changing the oil and filters, rotating the tires and refilling the washer fluid. But did you know that your air conditioning system needs routine maintenance as well? Taking care of your air conditioning system can extend its life and prevent costly repair bills.
Why is it important for St. Louis drivers to get routine maintenance on their air conditioning system? First, the refrigerant contains an added lubricant. As the refrigerant circulates through the air conditioning system, its parts are lubricated. This constant lubrication keeps the parts functioning well. But over time, this lubricant is used up, and without it, the parts will eventually seize up and fail.
Belleville folks should understand, however, that the air conditioner will continue to pump out cool air even without the lubricant, so you won’t know the system is sick until it actually dies. So good car care includes regularly checking the refrigerant and lubricant in your Sedan air conditioning system and replacing it if needed.
The second reason your air conditioning system needs preventive maintenance is that air and water can get into the system. Air, water and the contaminants they contain will reduce the efficiency of the air conditioning system and can cause corrosion of the system’s parts. Keeping the air conditioning system clean is a vital practice and will extend its life and keep you from losing your cool on hot St. Louis days.
How often should you get a routine car air conditioner inspection? It varies from vehicle to vehicle. Check your owner’s manual for the automobile manufacturer’s recommendation.
Here’s a good piece of auto advice for Illinois auto owners that will extend the life of their air conditioning systems: You should run your air conditioner in the winter every once in a while. This circulates the refrigerant, which lubricates the seals. That way, they won’t dry out during cold Belleville weather.
Your air conditioning system doesn’t just cool the air in your Sedan; it dries it out as well. So if you have trouble with a foggy windshield, flip on your air conditioning on the defrost setting. You may be surprised at how quickly it takes care of the problem. Of course, some vehicles can’t run the air conditioner and defroster at the same time; you should check your owner’s manual or with the auto manufacturer if you are uncertain whether this feature works in your car or not.
So, after learning about preventive maintenance for your A/C, you might now be wondering if your air conditioner is in trouble. Two early warning signs of a failing air conditioner are (1) the air just isn’t getting as cold as it used to and (2) there’s a strange noise when the air conditioner turns on. If you notice either of these symptoms in your Sedan, you should bring it to Stock's Underhood Specialists Inc. in Belleville as soon as possible.
Just some good auto advice to keep you cool in St. Louis and keep you on the road!
There are a lot of new features, both optional and standard, on Belleville drivers' vehicles these days. One you may not have heard of is called a cabin air filter. Simply put, its job is to keep the air in the passenger compartment of your car nice and clean.
A cabin air filter is similar to the filter you use on your furnace at home in Belleville. Cabin air filters can catch particles down to three microns. By comparison, a grain of sand is 200 microns. So cabin air filters are effective against dust, dirt, pollen, mold spores and most pollutants in our St. Louis atmosphere. Good news if you suffer from any types of allergies, or if you live in an area in Belleville prone to air pollution.
Cabin air filters are generally located in the engine compartment or under the dashboard. They can be tricky to access and replace, so you’ll probably want to go to your honest Stock's Underhood Specialists Inc. service professional to get it done. Check your Sedan owner’s manual to find out if your Sedan is equipped with a cabin air filter and how often it should be changed. Recommendations vary, but generally a cabin air filter should be changed every twelve to fifteen thousand miles.
Of course, if you are an allergy sufferer in Swansea, you may want to replace it more often. Also, if you do a lot of driving in polluted or dusty areas in Illinois, you’ll also want to shorten the cabin air filter replacement period. Dirty air filters just don’t work well, and they can exude an unpleasant odor if ignored for too long.
Most Belleville folks know that good car care includes keeping your Sedan clean, including the air inside the passenger compartment, so changing your cabin air filter should be part of your routine preventive maintenance. It’s good auto advice as well as good medical advice that an ounce of prevention is worth a pound of cure. You really shouldn’t wait until the interior of your car starts to smell and your eyes start to water before you change your filter. And trying to cover it up with a dangling green pine tree is not the right answer, either!
Cabin air filters can be a welcome relief to Belleville allergy sufferers, but they’re also a great idea for anyone in St. Louis who just wants to breathe better.
A good suspension system gives a vehicle a smooth, even ride while providing Belleville auto owners with good handling and control. But like any system on your Sedan, vital parts of the suspension system can wear out, leading to a lower ride quality and safety concerns. So it’s a good idea for Belleville auto owners to remember an inspection of their suspension system in their schedule of an essential preventive maintenance. Springs do most of the work of the suspension system. The most common types of springs are coil and leaf, but air springs and torsion bars are becoming more common. The body of the vehicle is “suspended” by the springs.
If springs were the only working component in your suspension system, however, you’d spend your travel time bouncing up and down like a bobblehead. That’s where your shocks come in. They keep the rebound, or bounciness, of the springs under control. Shocks also keep your tires on the road, which keeps the driver in control of the Sedan. Some vehicles have struts in their suspension system. Struts are a compact combination of springs and shocks. They do the same important job but in a single package.
Shocks wear out gradually, so it can be difficult for Belleville car owners to notice when they need to be replaced. There’s no definitive point when a vehicle’s ride goes from smooth and controlled to a bit imprecise. To check if your shocks or struts are worn, you should first do a visual inspection on them. If they are leaking fluid, they need to be replaced.
There are other less obvious signs that your suspension system needs important attention. For example, an uneven, cupping wear on your tires may indicate that your shocks are worn. If your vehicle feels “floaty” when you turn, or, in other words, you don’t feel that you have full control of the vehicle, you should check your shocks. Also, if the front end of your vehicle dips noticeably when you stop, it’s time for new shocks.
Your owner’s manual gives recommendations on how often the shocks should be checked, usually between 15,000 and 30,000 miles (24,000-50,000 km). If one of your shocks does need to be replaced, you should replace all four. This will keep your suspension even and ensure good handling of your vehicle. If you carry heavy loads, tow a trailer or drive on uneven St. Louis area terrain, you might also consider upgrading to a heavy-duty shock.
Regular shocks contain hydraulic fluid. The essential fluid helps them absorb the bumps or “shocks” of the road so the impact doesn’t transfer to the Sedan’s body. Premium shocks are filled with compressed nitrogen gas, which costs more but does a better job of controlling body motions. Regular shocks can develop air bubbles that reduce their effectiveness; the premium shocks don’t have this problem. So if you want higher handling performance, if you drive off-road around Illinois or if you just want added comfort, you should think about upgrading to premium shocks or struts.
Replacing struts can put your Sedan out of alignment, so an alignment check should always follow this type of repair. Talk to your honest service advisor at Stock's Underhood Specialists Inc. in Belleville.
A generation ago, Belleville motorists seemed to be more inclined to keep their vehicle’s preventive maintenance on schedule. One reason for this may be that vehicles back then were a lot less reliable than they are today. Having your Sedan in to your Belleville shop every year or two for repairs seemed to be a good reminder to keep the oil changed.
For example, almost everyone in Belleville used to take their vehicles in for regular tune-ups. Vehicles had mechanical ignition systems, which meant ignition points, spark plugs and coils had to be replaced and the timing adjusted every few years. As long as the Sedan was in for a tune-up at Stock's Underhood Specialists Inc., the vehicle was inspected and you took care of any needed repairs at the same time.
Today’s engines have electronic ignition systems and engine control computers. Spark plugs can last for up to 100,000 miles. Vehicle reliability has vastly improved in the last few decades, and surveys report fewer problems with new vehicles than ever before. That also means that our Sedans don’t experience a huge performance drop when they’re ready for some car care. But it doesn’t mean that they don’t need it.
Modern Belleville auto owners need to rely on calendars and mileage intervals to know when to schedule maintenance. Owner’s manuals contain recommendations on when different types of maintenance should be performed. Also, your Belleville service center can provide advice about auto maintenance schedules. At Stock's Underhood Specialists Inc. in Belleville, we know that benefits of staying on top of preventive maintenance are substantial. First, you’ll get better engine performance and fuel economy. Those two things alone return the cost of preventive maintenance: in fuel savings and safety. Also, routine maintenance has been proven to prevent major car repairs later on. Again, the cost savings can be significant. As the old saying goes, “Spend a penny, save a dime.”
Modern Sedan engines may be more durable and reliable than their predecessors, but they’re more sophisticated and complex as well. For this reason, preventive maintenance today is even more critical than the old tune-up. Modern engine systems have a lot of essential parts that have to stay lubricated. These parts can be made of aluminum, plastic or steel. Special additives in lubricants are required to keep each of these materials from breaking down or corroding. Over time, these additives are depleted, even if the Sedan isn’t driven. This makes fluid changes a critical part of scheduled maintenance if you want to keep your car on the road.
As an example, coolant fluid in your engine is a sophisticated mix that not only keeps your Sedan engine cool but also protects and maintains its components. However, this fluid gradually gets contaminated and anti-corrosion additives are depleted. It can become corrosive and actually damage the Sedan engine parts it was designed to protect. It can actually eat holes in your radiator and other engine parts. Changing the coolant could have prevented this expensive damage, and it’s a whole lot easier and cheaper than replacing a radiator.
Timely oil changes are more critical for Belleville car owners than they used to be. Skipping just one oil change can start the build-up of oil sludge in your engine. Sludge can clog small engine passages, which cuts off the supply of lubricant to critical engine parts. Just this small bit of sludge can reduce the life expectancy of your engine. If the build-up continues, it could lead to engine failure within two or three years.
One word of warning to anyone in St. Louis who purchases used automobiles: take care when buying a leased vehicle. Belleville folks who lease vehicles only intend to drive them for two or three years, generally the years when the vehicle is least likely to experience any problems. One of the reasons people lease vehicles is that they don’t want to be bothered with maintenance or car care. Before buying a pre-leased vehicle, be sure to inspect it for signs of damage that result from lack of proper care.
Belleville motorists can all be grateful for the improved reliability of our modern vehicles. With proper maintenance and care, we can expect them to last longer, perform better, get better fuel economy, and require fewer repairs than ever before. We just have to be more conscientious about scheduling time for their care.
The serpentine belt tensioner applies pressure to the serpentine belt, maintaining optimal tension to drive the accessories like the alternator and A/C compressor. The service life of the belt tensioner is the same as the belt itself, so they should always be replaced together. A worn tensioner inhibits the accessories from spinning properly, leading to premature wear and noise.
Your car maker has a recommended mileage interval for serpentine belt replacement. A complete accessory drive system service replaces the serpentine belt, the belt tensioner and any idler pulleys your car might have. Your honest Stock's Underhood Specialists Inc. tech can survey your system and let you know if it’s time for a replacement.

Engines get hot when they run. This heat can build up and damage vital engine parts, so engines need a cooling system to keep them running. Cooling system failure is the most common mechanical failure in vehicles. This is unfortunate, because these failures are usually easy for Belleville motorists to prevent.
The radiator is the best-known and most recognizable part of the cooling system. Hoses filled with coolant (also known as antifreeze) connect the radiator to the engine. The coolant draws heat from the engine, and then flows to the radiator. Air passing through cooling fins on the radiator cools the coolant. The coolant then cycles back into the engine to start the process over again.
The most critical component of the cooling system, however, is the coolant itself. A mixture of water and coolant/antifreeze helps keep it both from freezing and from boiling away. Either can result in serious engine damage.
Different engines require different types of coolant/antifreeze. The owner’s manual will list what kind a vehicle requires. Using the wrong type or mixing different types of may void the warranty on the cooling system and may damage it as well.
Insufficient coolant can lead to engine failure. Coolant levels need to be checked regularly and topped off as necessary. If coolant levels drop quickly or consistently, the cooling system should be inspected for leaks. Coolant/antifreeze contains additives that protect the radiator and other coolant components from rust, scale and corrosion. Over time, these additives are depleted, so it is necessary for Belleville motorists to replace coolant at specified intervals. Changing coolant should be part of routine preventive maintenance for any vehicle.
This service is often ignored, though, since old coolant still cools the engine. Vehicle owners don’t realize there is a problem until the system fails. They are left with major repairs and possibly a damaged engine, which could have been prevented with a cooling system service at Stock's Underhood Specialists Inc. in Belleville.
If your Sedan sends a warning message to check its coolant or if the temperature gauge is reading in the red or hot zone, then the cooling system needs an inspection. This service is critical and should not be put off since the potential for damage is high.
In an emergency situation, water or antifreeze can be added to your Sedan so that it can be driven to a service center for proper car care. For this reason, owner’s manual contains instructions for how to top off insufficient coolant – allow 45 minutes for the engine to cool before attempting to add coolant or water. However, the fluid should be added to the coolant overflow bottle, not to the radiator itself. Removing the radiator pressure cap can result in severe burns.
Topping off in an emergency, however, does not fix the problem. The vehicle should immediately be taken to your Belleville service center or Stock's Underhood Specialists Inc. where they can inspect the cooling system, repair any leaks, and clean it if necessary. They can identify what caused the emergency situation in the first place and ensure it doesn’t happen again.
Regular maintenance of a vehicle’s cooling system is just good auto advice for Belleville drivers. Cooling system service is relatively inexpensive and doesn’t take long at Stock's Underhood Specialists Inc.. Lack of it, however, can put a vehicle in the scrap heap.

The drive train in your vehicle includes all the important components that transfer power from the transmission to the wheels. Those components differ depending on what type of vehicle you drive, namely, front-wheel drive, rear-wheel drive, all-wheel drive or four-wheel drive. The preventive maintenance your driveshaft needs will also differ by what type of vehicle you drive.
Let’s start with front-wheel drive. In this vehicle, the transmission and the differential are combined in one component, known as the transaxle. The transaxle is connected to two half-shafts (axles), which are then connected to the wheels with a constant velocity (or CV) joint, which is protected by an airtight rubber boot.
Stock's Underhood Specialists Inc. service for this type of driveline includes servicing the transaxle and inspecting the CV boot. If the boot is damaged, the CV joint will need to be inspected, and the boot will need to be replaced. If you hear a clicking noise in your wheel wells when you turn, you may have a damaged CV joint. A damaged CV joint should be replaced.
Rear-wheel drive vehicles generally have a transmission in the front of the car and the differential in the back. A driveshaft (it looks like a long tube) connects the transmission to the differential. Some vehicles may have a two-piece driveshaft, which are connected to the differential with universal joints or U-joints. Again, the differential is connected to two half-shafts that go out to the wheels.
Stock's Underhood Specialists Inc. service on the drive train on a rear-wheel drive vehicle starts with servicing the differential. It will need its fluid drained and replaced regularly. The seals on the axles should also be inspected for wear or leaks. Leaking or damaged seals may mean the axle needs to be serviced as well. Also, U-joints can wear out. If you hear clunking or feel a jolt when you shift into drive or into reverse, it could indicate a driveline problem.
All-wheel drive Sedans provide power from the transmission to all of the wheels, instead of just to the front or rear. The advantage is that the vehicle can adapt to different driving conditions and transfer more power to the front or back wheels as needed. The disadvantages are that the driveline is more complicated, and the vehicle weighs slightly more.
Many all-wheel drive vehicles are based on a front-wheel drive set-up. They also have a differential in the rear and one in the center of the vehicle that allows power to transfer to the front and rear. A shaft runs from the transfer case to the center differential, and another from the center differential to the rear differential.
Servicing an all-wheel drive at Stock's Underhood Specialists Inc. involves servicing ALL of the differentials and inspecting the joints and seals for wear, leaks or damage.
Four-wheel drive vehicles are rear-wheel drive vehicles that have an option to transfer power to the front wheels. In other words, they can be driven as either rear-wheel or four-wheel drive vehicles. These vehicles are specifically designed for the harsh driving conditions Belleville auto owners encounter off-road. The driveline in a four-wheel drive vehicle is similar to that of an all-wheel drive vehicle. The center differential, however, is a transfer case. Maintenance requires servicing both of the differentials and the transfer case, as well as an inspection of the joints and seals.
Belleville drivers would be wise to check with their owner’s manual for recommendations on how often to service their Sedan drive train. It’s also good auto advice to check with your honest Stock's Underhood Specialists Inc. service professional as well. You may live in an area in Illinois where weather or driving conditions require more frequent servicing of the drive train.
If you drive off-road, it is critical to service your driveline more often frequently than the typical recommendation. Conditions encountered off-road around the St. Louis area are particularly hard on your driveline.
Good car care at Stock's Underhood Specialists Inc. in Belleville always includes taking care of your driveline. Without it, your Sedan becomes a very large paperweight.
Stock's Underhood Specialists Inc. is located at 321 Centreville Ave. in Belleville. We provide comprehensive auto repair and maintenance services for residents of Belleville, Fairview Heights, O'Fallon, Swansea and St. Louis.
Unless you live in Death Valley, you really don’t hear much any more about cars overheating. That’s because cooling systems in vehicles have been much improved. That doesn’t mean you can’t overheat your Sedan engine, though. Without proper preventive maintenance, you could still find yourself on the side of the highway in Belleville waiting for your Sedan engine to cool down.
When you service your cooling system at Stock's Underhood Specialists Inc., your technician will check the condition of the coolant. It can become corrosive over time, which can damage a radiator — leading to an overheated engine. Changing the coolant periodically is good car care. Your Sedan owner’s manual can give you guidelines on how often to replace it.
If your engine overheated, your honest service advisor will also check your coolant system for leaks. Check the Sedan radiator for cracks and the radiator hoses for leaks. He’ll also check your water pump. They don’t need to be replaced on a regular schedule, but they do need an automotive analysis regularly. They can and do wear out.
The water pump is a critical component of your Sedan cooling system. It pumps the coolant to keep it circulating through the engine. The coolant is cooled in the radiator, then it travels through the engine, where it absorbs heat, then it returns to the radiator, where it releases the heat. And so on. But a water pump is something of a misnomer. The fluid pumped through your Sedan cooling system is not just water. It also contains coolant, which is actually poisonous. You should never consider your radiator as an emergency water supply.
There are many types of coolant. It varies from vehicle to vehicle, and using the wrong kind could damage your engine. Your technician will know which kind your vehicle’s manufacturer recommends. The team of automotive professionals at Stock's Underhood Specialists Inc. is always a good source for auto advice. We've been providing quality automotive services at our convenient location in Belleville for 28 years.
Keeping your cooling system in good repair will help keep your engine running well, and keep you out of the St. Louis repair shop. This means that a regular cooling system inspection should be on your schedule for routine preventive maintenance of your vehicle. Your owner’s manual will tell you how often you need to do this. It varies depending on what kind of car you drive, what type of driving you do and where you live in Illinois.
At Stock's Underhood Specialists Inc., we help you keep your cool which will keep you in the driving lane.
