Smooth Shifting in Marlborough MO: Transmission Service

So you have some exciting plans for the MO weekend. You’re going to take some of your Marlborough, MO friends out on the boat for some water skiing. Of course, you’ve gotten the boat all ready. And you haven’t forgotten about your tow vehicle. You’ve gassed it up and even vacuumed it out. However, there is something even more vital than the cleanliness of the interior: you want to make sure that your pickup maintenance is up to date.

Think about it – heavy interstate traffic on the way out of Marlborough. There’s hilly terrain as you get to the lake. Some dirt roads – and it’s going to be pretty hot in Marlborough this weekend. And all the time you’ll be towing around several thousand extra pounds. That all adds up a lot of severe strain on your engine, brakes and transmission.

Let’s just consider the transmission. It’s going to be working overtime, spending more time in lower gears. The internal transmission temperature is going to be much higher than normal. A fun little blast to the local MO lake for you is really severe duty for your transmission.

It’s essential to have enough transmission fluid. If it runs low, the transmission will run hotter and won’t have the protection it needs to cope with the added stress of towing. Transmission fluid breaks down and gets dirty over time. Whether you have an automatic or manual transmission, it’s essential for Marlborough auto owners to have it serviced by automotive professionals like the team at Carsmart Auto Service in Marlborough to make sure it runs efficiently.

An automatic transmission contains a maze of passages through which the fluid must pass to keep it shifting smoothly. Marlborough auto owners who neglect regularly scheduled transmission service risk the passages clogging up and starting to have problems.

Marlborough drivers who neglect their transmission for too long will eventually experience expensive transmission failure. You really don’t want to pay for a major transmission repair.

This reminds us of how much of our driving around Marlborough, MO is under severe conditions. Towing or hauling a big load is obvious, but there are lots of other things that constitute severe driving conditions. Things like short trips, driving in very hot or very cold MO weather. Dusty roads and city driving around Marlborough, MO add to the strain. Basically, any driving that’s not at highway speeds or under ideal conditions.

While you have your vehicle in, ask for a trip inspection. Your service professional at Carsmart Auto Service will check your belts and hoses and let you know if your brakes are in good shape.

Now, don’t forget the sunscreen.

Carsmart Auto Service Radiator Service

The coolant system is a vital part of your vehicle. It is also the second most common cause for vehicle failures. Even though coolant system failure is fairly common in Marlborough, it is easy to prevent.

The most recognizable part of the coolant system to Dupo car owners is the radiator. It is connected to the engine with hoses and is filled with coolant. The coolant draws heat off the engine and then passes into the radiator. Air passes through cooling fins to reduce the temperature of the coolant and then it’s back to the engine again.

There are several ways for the cooling system failure. Most common is with the coolant itself. Coolant is comprised of water and antifreeze. The proper ratio keeps the coolant from either boiling away or freezing. Understandably, either can lead to massive engine damage.

Another critical coolant issue that is often overlooked by Marlborough drivers is the age of the coolant itself. Antifreeze has additives that protect the coolant system from corrosion. As these additives are depleted over time, they can’t protect the radiator and other parts from rust, scaling and corrosion. That old container of coolant gathering dust in your garage may still keep your engine cool, but it won’t protect it from corrosion.

If get a warning message to check the coolant or if the pickup temperature gauge is in the hot zone, your cooling system needs to be checked. It’s OK to add water or antifreeze yourself. But you need to be cautious. Remember four things:

  • First, you never want to open the radiator pressure cap. You could be severely burned.
  • Second, get to Carsmart Auto Service in Marlborough immediately if your coolant is low. If that is not possible, follow the directions in your pickup owners manual – it will direct you to only make additions to the coolant overflow bottle.
  • Third, remember that you need a proper mixture of water and antifreeze. If you make an emergency addition to your cooling system, follow-up with your Carsmart Auto Service service center where we can make necessary adjustments.
  • Fourth, not all cars use the same type of antifreeze. You need to check your pickup owners manual to make sure you use the right kind. Mixing antifreeze types or using the wrong kind of antifreeze may void the manufacturers warranty on your cooling system. Again, another reason to depend on your Carsmart Auto Service service center in Marlborough to do things right.

Remember, your Marlborough service center has the equipment to change your coolant quickly and inexpensively.

Suspension Service In Marlborough At Carsmart Auto Service

When they hear the word ‘suspension,’ Marlborough car owners may think back to those energetic days of grade school. Well, your car’s suspension is actually a good thing because it keeps your car up off the road and helps provide a comfy ride around Dupo. Its job is to keep your wheels firmly planted over bumps and through curves. Your suspension system has many important parts. If you look under your car, it’s basically everything that connects your wheels to the pickup’s frame. These are heavy duty parts that do a lot of work. They need to be inspected for damage and excessive wear at least once a year. A good time for this is when you get your annual alignment service at Carsmart Auto Service.

Here are some warning signs of suspension problems:

  • the car pulls to one side
  • it wanders
  • the steering is erratic
  • you see uneven tire wear
  • you experience a poor ride or handling
  • you see oil leaking from shocks

Basically, you just don’t feel in control when you’re driving.

Some suspension parts just wear out with use. Shocks and struts eventually lose their ability to control your ride. Wheel bearings need to be repacked every couple of years. And some suspension pieces need to be lubricated when you get your oil changed. Your courteous service advisor at Carsmart Auto Service can perform an inspection and tell you what problems you may have.

If you’re in an accident, your suspension can be damaged or knocked out of alignment. Even a minor accident, like hitting a curb around Marlborough or even a large rock can mess things up for Marlborough drivers. With a minor accident it’s tempting for many Dupo auto owners to just get an alignment or wheel balance to correct the problem. But if there’s damage, a simple alignment won’t actually fix the problem, and you’ll just have to align it again after the repairs are made. So if you have an accident, get your suspension system inspected right away. Suspension problems are a major safety issue because they can lead to unsafe handling.

One big cause of suspension damage for Marlborough drivers is potholes – those nasty magnets that form in Dupo roads in freezing weather. They seem to draw our tires right into them. Here are some tips for avoiding damage from potholes: First, keep your tires at their full air pressure. That gives tires their maximum resiliency and will hopefully keep your wheels or other suspension parts from crunching on a big hole. Next, just pay attention. When you see a hole you can’t miss, slow down before you hit it. Driving at a slower speed will limit the damage, and may keep your drink from spilling. But avoid the temptation to brake directly over the pothole. That will cause the car’s weight to shift forward and add to the potential damage.

Differential Service At Carsmart Auto Service

Here at AutoNetTV, we have national viewers, like your neighbors in Marlborough, who write to us with questions or feedback. One common question we’re asked is: “What is a differential and what does it do?” You may have been told by your Carsmart Auto Service service professional that your differential needs service, or seen it as an option up on the service menu. Differential service at Carsmart Auto Service covers a lot of things, so let’s first talk about what a differential does.

As you drive through a turn, your outside wheels and inside wheels turn at different speeds. Kind of like the cars going around a race track – the ones driving in the outside lanes have a greater distance to travel than the cars in the inside lanes. The differential is what allows the outside and inside drive wheels to rotate at slightly different speeds so that the tires don’t hop or skip while taking corners, or lose traction in dirt or snow on Dupo interstates. Differentials have gears in them that transfer the power from the drive train to your wheels – which is why they’re often referred to as gear boxes. The gears need to be very strong to do this work, and they need to be properly protected so that they’ll last.

All vehicles in Marlborough have some form of differential. If you have a front-wheel drive car, your differential is sometimes called a transaxle and is located in the front. If you have rear-wheel drive, the differential is in the back of the car. Marlborough motorists with a four-wheel drive vehicle have a differential in the front and the back – and in the middle as well. The center differential adjusts for differences in speed between the front and rear wheels.

Differential fluid lubricates and cools the gears. Over time, the fluid can get dirty from bits of the gears grinding off. The additives that keep the fluid clean and protect the differential break down over time. So your auto manufacturer has scheduled intervals for you to have your differential fluid changed. Talk to your courteous Carsmart Auto Service service professional if you are not sure about your recommended schedule.

Differentials are hard working mechanisms, and, along with the gears in a manual transmission, need to be serviced regularly at Carsmart Auto Service with high-quality, replacement fluid. Your Marlborough tech can give you more information as to when your next differential service is recommended. You can also ask if they have a record of when the service was last completed.

As with most service intervals, if you are driving under more severe conditions in the Dupo area, you will want to service your differential more frequently. “Severe service” conditions are  defined in vehicle manufacturers’ owners’ manuals, and include: frequent starts and stops, short trips, cold MO weather, hot weather and towing. All these factors add to the stress of the vehicle and its parts. Also, off-roading in MO can be especially hard on differentials, especially if you cross streams. Proper service at Carsmart Auto Service will extend the life of your gears and keep them running more smoothly. If you have never had your differential checked, visit http://carsmartstlouis.com/contact.html for more information.

The Carsmart Auto Service Guide to Proper Fluids for Your Vehicle

The automotive professionals at Carsmart Auto Service would like to give Marlborough car owners an update on some of the things happening in automotive fluids. You know, cars are becoming more sophisticated everyday – and fluids such as, oil, coolant and transmission fluid are becoming more specialized at about the same pace.

The Dupo do-it-yourselfer has to be pretty careful so that they do not actually harm their pickup with the wrong type of fluid. That is why so many MO car owners rely on the advice of their courteous Carsmart Auto Service service advisor to not only get the correct family of fluids, but to suggest the formulation that is best for their car and their driving habits in the Marlborough area.

Let’s start with engine oil. East Carondelet motorists who have been paying attention, will have noticed a number of new oil weights on the MO scene in the last several years. Modern engines are built to much tighter tolerances and have very complicated valve trains. The oil must be thin enough to lubricate complicated parts when the engine is cold. The weight of an oil is expressed in terms like 20-W-50 or 5-W-30. The automakers recommend the weight of oil for each vehicle they make. The recommendation is based on engine design. Your Marlborough service center will know what weight your vehicle manufacturer recommends – and it’s important to follow those recommendations. Your service specialist at Carsmart Auto Service can also offer suggestions for special formulations and can tell you all about conventional and synthetic oils.

Antifreeze,
or engine coolant, is another area that has become more complicated. For a long time, auto manufacturers only recommended a couple of different types of coolant. Now, several different formulations are needed because of the high-tech materials that automobile manufacturers are using to build the cooling system. Using the wrong type of coolant in your pickup or other vehicle can actually void your warranty, so it’s essential to get that right.

Transmission fluid is becoming specialized for Marlborough vehicles as well. New transmission designs have particular requirements that require specific formulations. Recently, new, somewhat confusing, standards for brake fluid have also been released.

Not too long ago, there was a good chance that all of the vehicles at your Marlborough house would use many of the same fluids. However, as automotive technology advances, the array of basic automotive fluids MO auto owners need will grow. And, some of the formulations will cost a little more for Marlborough auto owners. Fortunately, Carsmart Auto Service will continue to update their training to keep pace with technology so that you’ll get the right fluids your car needs. It’s all part of the commitment we make to your driving peace of mind.

Power Steering Service In Marlborough

Most Marlborough drivers are too young to remember life before power steering – cranking those great big steering wheels! It was a pretty good workout. Now power steering is standard. Let’s look at how it works. The heart of any power steering system is its pump. The pump pressurizes the power steering fluid that provides assist for steering. Most pumps are driven by a belt that is run by the engine – a few are electrically powered. A high-pressure hose passes fluid from the pump to the steering gear. A low pressure hose returns the fluid back to the pump.

These hoses can develop leaks, so it is a good idea fir Marlborough drivers to have them inspected at every oil change. Low fluid can damage the power steering pump. That is why fluid level is on the checklist for a full-service oil change. The fluid needs to be compatible with the hoses and seals, so check your owners’ manual for the right type – or just ask your courteous service professional at Carsmart Auto Service in Marlborough.

The fluid cleans, cools and lubricates the power steering system. It breaks down as the years go by and collects unwanted moisture, so Marlborough drivers need to replace it from time to time. Many automakers specify power steering service intervals. Unfortunately, this important service is sometimes left off the car maintenance schedule for many of us in Dupo. So, when in doubt, every 25,000 miles/40,000 km or two years is a good fallback. Your courteous Carsmart Auto Service service professional  will use a detergent to clean the system, flush out the old fluid and replace it with the good stuff.

Here are some critical warning signs of trouble with your power steering: It’s harder to turn the wheel, there’s erratic power assist, you hear loud whining coming from the pump (which may be difficult to hear over the loud whining coming from the backseat), you have to top-off the fluid frequently, or you hear squealing belts. Remember to never hold the steering wheel to the far right or left for more than a few seconds at a time. That will wear out your power steering pump real fast.

Other vital steering components can be bent or damaged from wear or hard knocks. Ball-joint, idler-arm, steering-gear, steering-knuckle and tie rod to name a few. Warning signs here are steering play, wandering, uneven tire wear, and off-center steering wheel. An annual alignment check at Carsmart Auto Service in Marlborough will reveal bent or damaged steering components.

Most SUV’s, pick-ups and rear-wheel-drive cars need regular front-wheel-bearing service.

The bearings should be cleaned and inspected. If they are excessively worn, they need to be replaced. The bearings are then repacked in clean grease. The team at Carsmart Auto Service also recommends the wheel-seal be replaced when the bearings are serviced. Like everything else, check your owners’ manual maintenance schedule. It’s usually required around every two years or 40,000 miles/64,000 km. If you drive through water in the Dupo area, the bearings will need service more often.

Air Conditioning Service In Marlborough

Hey Dupo! Let’s talk about one of our MO summertime must-haves: your car A/C. It’s real easy for Marlborough auto owners to take their car’s air conditioner for granted. Just push the right buttons and out comes cool, dry, clean air. But your air conditioning system needs attention from time to time to help it keep its cool.

Do you hear loud noises under the hood when you turn on your air conditioner? Do you only get cool air sporadically? If so, it is time to get your air conditioner checked at Carsmart Auto Service in Marlborough. 

When most Dupo folks hear the words “air conditioning problems“, it sends a shiver up their spine. That is because the air conditioning system is fairly complex. It has a lot of parts and when it’s broken, it’s pricey to repair.

What things can Marlborough and East Carondelet car owners do to prevent air conditioning breakdowns?

A common cause of air conditioning failure is leaks. Water and air can leak into the system. It doesn’t work as well with air in it and water can cause rust that leads to damage of the car A/C components. Also, refrigerant, the stuff that makes the air cold, can leak out, reducing the efficiency of the system, making it work harder to cool the air. Periodically evacuating the air conditioning system and recharging it keeps the proper amount of clean refrigerant in the system so it cools better and lasts longer.

Marlborough auto owners should run their air conditioner regularly, even during MO winter, so that it lubricates itself and keeps the seals from drying out, which leads to leaks. Your owner’s manual will have recommendations for how often to service your air conditioner. Of course, if it’s not working right, now is the time to get it checked. The team at Carsmart Auto Service in Marlborough can inspect and test your air conditioning and offer evacuation and recharge services. This helps you avoid expensive repairs.

New environmental laws have stopped the manufacture of Freon, a refrigerant that was common in cars made before 1993. There is a very limited supply of Freon in  MO so the price is very steep. It may not be worth its weight in gold, but it probably is worth its weight in silver. If you have an older pickup that uses Freon, you may want to consider having it retrofitted to use the new R134-A refrigerant. It will pay for itself in the long run. So, if your A/C is just a lot of hot air, bring it in to Carsmart Auto Service in Marlborough for an inspection.

Winter Tires

What type of technology do you use? Do you prefer an 8-track tape or an iPod? When it comes to winter tires, much of Marlborough drivers’s perception dates back to when 8-track was the best way to listen to the Bee Gees.

Twenty years ago in Marlborough, winter tires differed from highway tires only in their tread design. Marlborough motorists called them snow tires back then and they had big, knobby lugs that were designed to give good traction in deep snow. They had the same rubber compound as regular tires and they weren’t very good on ice, packed snow or wet MO roads. They were not even very good on dry roads. They really helped in deep or loose snow, but they did a poor job the rest of the time. They were loud and rode hard. Marlborough car owners couldn’t wait to get them off in the spring.

Then all-season tires started to appear in Marlborough tire shops. All-season tires are really a compromise between summer and winter performance. They have acceptable hot weather ride and tread life, and can get Marlborough auto owners through mild winter road conditions OK. But there are some really good reasons to consider winter tires.

Modern winter tires do a terrific job for Marlborough motorists in a wide range of MO winter conditions. First of all, below 45 degrees Fahrenheit, regular tires become hard and inflexible. That means they don’t provide the road grip Marlborough drivers need. Even if you don’t live somewhere in MO with a lot of snow, but it still gets below 45 degrees in the winter, you will be safer with winter tires.

In addition, they are specifically designed to more effectively move snow and water. That’s the key to traction on ice, packed snow and wet  Dupo area roads. They use a micro-pore compound that allows the tire to bite into ice and snow. They also use wider grooves that run around the circumference of the tread to expel snow from the tire better. The lugs and grooves on winter tires have a special shape that throws the packed snow out of the tread as the tire turns. The tread is then open when it comes back in contact with the road and can provide good traction for MO drivers.

Winter tires also have a lot of sipes. Sipes are thin slits in the tread. The edge of the sipes grab ice and packed snow to provide tons of traction and to expel water and slush out of the tread. Winter tires have a rounder casing to cut into the snow’s surface. The treads on regular summer tires can actually get packed with snow instead and become very slick. Winter tires offer 25% to 50% more traction for Marlborough car owners than all-season tires. And when it comes to stopping power, all-season tires take 42% longer to stop than winter tires. Sometimes that’s the difference between getting home safely and spending the night in a snow bank.

Now back when the 8-track was king, Marlborough car owners just put snow tires on the drive wheels. That worked out OK because the rubber compound was essentially the same. Now, winter tires provide so much more traction than all-season or summer tires, that there’s a huge difference between the traction at the front and rear ends of the car if you only put winter tires on the drive wheels.

For example: if you take a corner on an icy road and the rear end starts to slide out, essentially the rear is trying to pass the front because it’s going faster. If you have high traction winter tires only on the front, they are going to be much more effective at transferring cornering grip and stopping power to the front wheels. This will actually cause the rear end to whip out even more.

That’s why tire manufactures instruct their dealers that they must install winter tires on the rear wheels as well whenever they put winter tires on the front end of any vehicle. It’s a major safety concern. Marlborough car owners are strongly recommended that winter tires be installed on all four wheels on rear wheel drive vehicles as well. The front tires do most of the steering and braking work – it only makes sense that you provide the front end with the best traction you can.

Marlborough car owners often assume that if they have four-wheel drive or all-wheel drive they don’t need winter tires on all four wheels. Would you intentionally disconnect the four-wheel drive in poor road conditions? Of course you wouldn’t, but that’s essentially what you do if you only put winter tires on one end. It only makes sense to have the same level of traction and control at all four corners.

The province of Quebec in Canada has issued a law requiring all passenger vehicles, taxis and rental cars with Quebec license plates to install a full set of four winter tires between November 15th and April 1. It’s that important.

Many modern cars have traction control and anti-lock brakes so Marlborough motorists may think that they don’t need winter tires. But you need traction to accelerate, steer and stop. The tires provide the traction so that the traction control and anti-lock brakes have something to work with.

Look for tires with the symbol of a mountain with a snowflake in it. This means the tire complies with the severe snow standard. Marlborough all-season tires will have an M&S, for mud and snow, on the sidewall.

So when the Marlborough temperatures drop below 45 degrees, be sure you have a set of four winter tires for maximum performance in snow, packed snow, ice, wet and dry roads. Your courteous Carsmart Auto Service tire professional can help you find the right winter tire for your vehicle and driving needs.

Trip Inspection at Carsmart Auto Service in Marlborough

Dupo drivers love their cars. And one of the most enjoyable things about them is taking a road trip. Freedom from daily schedules, new sights and the open road – it’s great! But there’s nothing like car trouble to bring the fun to a grinding halt.

Now Marlborough car owners can’t always avoid problems, but you can take steps to reduce the probability of getting sidelined on your trip. The first step is to look at your trip plan from your vehicle’s perspective. What kind of roads will you be traveling – winding MO byways or expressways? Purple mountain majesties or fruited plains? What weather conditions are you likely to encounter? How many miles will you travel each day? How much weight will you be hauling – passengers and luggage. Pulling a trailer, roof top carrier, or ATVs? Will it be dusty?

Prepared with answers to these questions, you can schedule a trip inspection at Carsmart Auto Service in Marlborough to help you prepare your pickup for your big adventure. A lot of our Marlborough customers prefer to go through this exercise with their courteous  service professional to get their input and make sure they haven’t overlooked anything.

A great place for Marlborough motorists to start is with the tires. Inspect them for tread wear and proper inflation. Is it time to rotate your tires? Replace them? Are they up to the job – you wouldn’t want to drive regular highway tires on a muddy off-road adventure on Marlborough rock-crawling trails. 

Shocks and struts play a major role in both driving comfort and safety. If they need to be replaced, you’ll really be glad you did once you hit the road. Is it time for a wheel alignment? Fighting a car that’s pulling to one side all day can be tiring and dangerous for Marlborough car owners. 

And don’t forget your brakes, Marlborough drivers. Any strange noises, grabbing, soft or hard peddle feel? If there is any doubt, get a brake inspection at Carsmart Auto Service in Marlborough before you leave.

Moving under the hood, have a belts and hoses inspection. If something is excessively worn or near failure, the stress of a long road trip might just be the straw that breaks the camel’s back. Talk to your courteous Carsmart Auto Service technician.

Your engine air filter will be important. For every gallon of gas you burn, your car will filter and use 12,000 gallons of air. If the filter needs to be changed, you’ll notice improved MPG on your trip.

How close are you to your next oil change? Will you be able to complete your trip before it’s due? If not, just get it taken care of before you go so that you don’t need to interrupt your trip. In fact, a full service oil change at Carsmart Auto Service is a great idea because they will top off all your fluids and check to see if any other important maintenance items are due, such as transmission or cooling system service.

Do you notice any unusual odors in your pickup? If so, it could as harmless as a dirty cabin air filter. But if it’s an exhaust leak it could be fatal for Marlborough car owners and their passengers on a long trip. Of course you’ll want to be comfortable, so get an air conditioning service if you aren’t getting the cold air you used to. 

Are your wiper blades still working well? If not, that is quick and inexpensive to fix for bright Marlborough auto owners. Headlamps are often overlooked when planning for a trip. If you haven’t changed the bulb in six months or so, replacement bulbs will really light up the night on your trip and provide the necessary after-sundown visibility.

All the items mentioned are part of any good vehicle maintenance plan. These are things that you want to take care of anyway, but they all become more important as you plan for your trip.

They will always save you money in the long run and may prevent inconvenient and costly delays on your trip. After all, you wouldn’t want to miss the world’s largest ball of string, would you?

PCV Valve Replacement

Hello Marlborough car owners, let’s talk about your often-unnoticed but extremely critical PCV valve. The energy from exploding fuel is what powers your engine. But some of the vapors from the explosions escape into the lower part of the engine, called the crankcase. The crankcase is where your engine oil hangs out. These gases are about 70% unburned fuel. If the gases were allowed to stay in the crankcase, they would quickly contaminate the oil and turn it to sludge. Dupo folks know that sludge is one of the biggest enemies of your engine, clogging it up, eventually leading to expensive failures. Also, the pressure build up would cause seals and gaskets to blow out. Therefore, these gases need to be vented out.

Pre-1963, gasoline engines had a hose that let the dangerous fumes vent out into the air. In 1963, the federal government required gas engines to have a special one-way valve installed to help reduce dangerous emissions. (Can you imagine how polluted our Dupo air would be if every car had been releasing those poisonous fumes for the last fifty years?) Diesel engines are not required to have these valves.

The positive crankcase ventilation, or PCV, valve routes crankcase gases through a hose and back into the air intake system where they are re-burned in the engine. Fresh, clean air is brought into the crankcase through a breather tube. It’s really a pretty simple system, but it does the job. The re-circulating air removes moisture and combustion waste from the crankcase, preventing sludge. This extends not only the life of your oil, but the engine as well. The PCV relieves pressure in the crankcase, preventing dangerous oil leaks.


Eventually, the PCV valve can get gummed up
. Then it can’t move enough air through the engine to keep it working properly for Marlborough auto owners. If the PCV valve is sticking enough, you could have oil leaks, excess oil consumption and a fouled intake system. If you experience hesitation or surging or an oil leak, it may be a sign of PCV valve problems. Your vehicle manufacturer’s owners’ manual may give a recommendation for when the PCV valve should be replaced – usually between 20,000 mi/32,000 km and 50,000 mi/80,000 km. Unfortunately, some car makers don’t list a recommendation in the manual, so it can be easy to overlook.

Many PCV system problems can be diagnosed with an inspection by your courteous Carsmart Auto Service service advisor. Fortunately, PCV valve replacement is both quick and inexpensive at Carsmart Auto Service. Proper oil changes will greatly extend the life of the PCV valve. Skipping a few recommended oil changes can allow varnish and gum to build up in the valve, reducing its efficiency. So now when your Marlborough service technician tells you its time to replace your PCV valve, you will know what he’s talking about. If you have had your car for a while and this is the first you’ve ever heard of a PCV value, ask your tech to check yours out or call Carsmart Auto Service at 314.968.9496.
