The Check Engine Light strikes fear into the hearts of some Marlborough auto owners and is totally ignored by just as many. Just what it means is a mystery to most of us Marlborough motorists.
Let’s get the urgency issues out of the way first. If your check engine light is flashing, that means that something is wrong that could cause critical engine damage. Naturally, you need to get that taken care of right away. If your check engine light is flashing, you shouldn’t drive at MO highway speeds, tow or haul heavy loads. Take it easy all the way to your Marlborough service center.
If the light is glowing steadily, you should keep an eye on it for a day or two. If the light doesn’t go off, schedule an appointment with your courteous Carsmart Auto Service service professional to get it checked out.
Some more Marlborough information on how the Check Engine Light works may be informative for Marlborough car owners. Most of your engine functions are controlled by a computer, not surprisingly, called an engine control computer. The computer is able to adjust many engine parameters for environmental conditions, engine condition and even the way you drive.
In order to make these adjustments, the computer relies on a network of sensors to provide data. The computer knows the proper operating range for each sensor. When a sensor reading is out of range the computer runs some tests and may turn on the pickup’s Check Engine Light.
A simple example is a loose or missing gas cap. This may cause one of the sensors to read out of range. The computer doesn’t know if it’s a serious condition that caused the reading or just a loose gas cap, so it stores a trouble code and turns on the Check Engine Light.
Now when you tighten up the gas cap the sensor readings will be in the correct range. The computer will keep checking on the report for a day or two. Since a bad reading didn’t come up again, it turns off the Check Engine Light. The computer will also try to make adjustments to compensate for some readings. If it can do so, it’ll then turn off the Check Engine Light.
If the problem can’t be resolved then the light will remain on and you should get your pickup looked at. Your courteous Carsmart Auto Service service specialist will plug a scanner into the on-board diagnostic port and read the trouble code stored in the computer. The trouble code will give the technician a starting place as he diagnoses the cause of the problem.
Have you checked out the price of new vehicles at Marlborough car dealers? Ouch! Add financing and insurance and – well a new ride may not seem so attractive. A lot of Marlborough, MO folks are hoping to make their cars last a lot longer.
Fortunately, with the current state of automotive engineering and manufacturing, there’s no reason a modern vehicle can’t be made to last for a 150,000 miles or more for smart Marlborough motorists.
The old adage: ‘a stitch in time saves nine’ is really true for Marlborough auto owners when it comes to car maintenance. A great example is coolant service.
Over time, coolant becomes corrosive and actually starts to damage your radiator and other parts. Smart Marlborough motorists have their cooling system service taken care of right on schedule.
Ditto for your power steering system, brake fluid, air conditioning system, differential and transmission. Of course, oil changes should be done right on schedule to avoid the build-up of harmful oil sludge.
Don’t let your brake pads go too long before they are worn to the point that your rotors are at risk. Preventative auto maintenance at Carsmart Auto Service is a great way to keep your operating costs down in Marlborough.
Replacing belts and hoses is much cheaper than repairing the costly damage that can be caused by failure.

We’re going to be talking about the ethics of automotive repair. It seems like news outlets really like hit-and-run reporting; they hit everyone from groceries stores to retail to physicians. And the Marlborough automotive service and repair industry hasn’t been given a pass either.
Unfortunately, every profession in Marlborough has some bad actors that hurt the reputation of everyone else. On the automotive side, industry associations and professional licensing organizations are very committed to high ethical standards.
Yet some people remain uncomfortable with Marlborough automotive service and repair. It may start with the fact that our vehicles are a big investment and we rely on them for so much in our lives. That alone guarantees our attention. And how well we understand the recommendations really impacts our comfort level.
If we understand what’s recommended and the benefits of taking care of the work – and the pitfalls of putting it off – we’ll have more trust in the recommendation. So communication is key. It’s like going to the doctor; If she’s using medical jargon and takes a lot of basic medical knowledge for granted, we have a hard time following her train of thought. It can be like that with your Marlborough service advisor too. He’s so familiar with all things automotive, he may forget you don’t know a PCV from an EGT.
If you don’t understand what your doctor’s talking about: ask some questions. If you don’t understand what your Marlborough automotive advisor’s talking about: ask some questions.
Let’s go back to those ethical standards; when we hear a repair recommendation, we always ask ourselves, “Is this really necessary?” Well, here’s the industry standard:
If a technician tells you that a repair or replacement is required it must meet the following criteria:
The part no longer performs its intended purpose
The part does not meet a design specification
The part is missing
For example, it you take your car in for a grinding noise when you step on the brakes, you may just think you need new brake pads. After the inspection, the technician at Carsmart Auto Service says that you have a cracked rotor and need to replace it.
If you tried to get him to simply put new pads on, he would say that if you didn’t want to replace the rotor; Carsmart Auto Service would ethically have to refuse the repair.
To just put pads on a cracked rotor would have been very wrong. The brakes could’ve failed at anytime and needed to be repaired – not just have a band-aid slapped on them.
Now, looking at something not so serious, the technician may suggest repair or replacement if:
The part is close to the end of its useful life – just above discard specifications or likely to fail soon
To address a customer need or request – like for better ride or increased performance
To comply with maintenance recommended by the vehicle’s manufacturer
Based on the technician’s informed experience
Of course, the technician has the burden of making ethical recommendations and properly educating their customers. For the customer, if you are uncomfortable with a recommendation, ask some questions. More information is always a good thing.
One Marlborough automotive service issue that doesn’t get much attention is driveline service. Drivelines don’t get talked about very much around Dupo, but they’re very important. First let’s define what the driveline is:
Taking a small step back, the power plant is comprised of the engine and transmission. The driveline starts there and includes all of the components that transfer power from the transmission to the wheels.
That’s not really a lot of components, but they handle the full force of the engine. Without the driveline you’re not moving. So Marlborough auto owners need to take good care of it. The driveline components differ depending on whether your vehicle has front wheel drive, rear wheel drive, all wheel drive or four wheel drive. For purposes of our discussion, we’re going to have to oversimplify a bit.
If you are ready to have your drive train looked at, give us a call: Carsmart Auto Service 7921 Watson Road Marlborough, MO 63119 Call Us at 314.968.9496
Let’s start with front wheel drive. The point where the transmission stops and the driveline begins is a little blurred with front wheel drive because the transaxle houses both the transmission function and the differential function. The half shafts that send power to each front wheel, come out of the transaxle. The shaft is connected to the wheel by a constant velocity, or CV, joint. The CV joint is protected from dirt and water by an airtight, flexible rubber boot.
So, Carsmart Auto Service driveline service would include properly servicing the transaxle and inspecting the cv boot to see if it’s torn or loose. If it is, it needs to be replaced and the CV joint inspected for damage. Repairs may be in order. Besides visual damage to the airtight CV boot, you might hear a clicking noise when turning. Recommended maintenance for the transaxle and CV joints will be spelled out in your owner’s manual or check with your courteous Carsmart Auto Service service professional.
On to rear wheel drive. The driveline for a rear wheel drive vehicle starts with the driveshaft – that long tube that connects the transmission with the differential on the rear axle. Some vehicles in Marlborough have a two piece drive shaft. The shafts are connected to the transmission and the differential with big universal joints. Most Marlborough motorists have probably heard the term ‘u-joints‘. These joints can wear out, just like the CV joints in front wheel drive vehicles. You may hear some clunking or feel a jolt when shifting into drive or reverse – if you do, get your driveline inspected at Carsmart Auto Service in Marlborough.
The differential on the rear axle sends power out to each rear wheel through half shafts in the axle. The differential fluid needs to be drained periodically and replaced with clean fluid. When the seal on the end of the axle is damaged or leaks, the axle will need to be serviced. The routine maintenance item here is differential service. Be sure to check your owner’s manual or Marlborough service advisor for intervals.
Now let’s go on to all wheel drive. Remember that the difference between all wheel drive and four wheel drive is that an all wheel drive vehicle is essentially providing power to all of the wheels all of the time. The pickup may be able to shift more of the power to the front or to the back depending on where you need traction. All wheel drive vehicles are designed to work well on dry pavement. Even some high-end sports cars from makers like Lamborghini and Porsche have all wheel drive.
Some all wheel drive vehicles are designed to work well off-road in Marlborough, but all hard-core rock crawlers are four wheel drive. These guys thrive in mud, sand, rocks and hills – but they don’t work well on dry pavement when they’re in four wheel drive. So they have the option to shift to rear wheel drive only on dry pavement.
Most all-wheel drive vehicles are very similar to front wheel drive when it comes to the front end. They also have a center differential that transfers power to the rear differential. Connecting it all is a shaft from the transaxle to the center differential and another from the center differential to the rear differential. So all of the normal front wheel drive service is critical as well as service to the center and rear differentials.
Four wheel drive can be thought of as a rear wheel drive vehicle that can also send power to the front axle. There’s a transfer case in the middle of the vehicle that can be shifted to send power through a drive shaft to a differential on the front axle. So Marlborough car owners need differential service for the front and rear differentials and for the transfer case as well.
The bottom line for Marlborough auto owners is that the maintenance schedules are in your owner’s manual. Your Marlborough service advisor can answer any questions you’ve got. If this is the first time you’ve heard some of this stuff – it’s time to ask someone at Carsmart Auto Service if any of it needs to be done now.
Marlborough auto owners know that engines need to burn fuel to operate. Fuel is pumped from your fuel tank to your pickup engine where it is squirted—or injected—into your engine’s cylinders. This is the function of the fuel injectors.
There are two ways to inject fuel into an engine. Fuel needs air to burn, so in the first method, fuel is injected into a port and allowed to mix with air and before it is drawn into the cylinders. In the second method, fuel is injected directly into the cylinders and mixes with air after it enters the pickup engine.
Direct injection engines burn fuel more efficiently than conventional pickup engines. Some models can deliver the power of a V8 with the economy of a V6.
For example, in one family of engines, the conventional version (a V6) delivers about 250 horsepower. The direct injection version delivers over 300 horsepower and gets about the same gas mileage. The turbocharged version delivers 350 horsepower.
Why the big difference in power? Direct injection systems allow fuel to be squirted into the pickup engine at hundreds of times the pressure of a conventional engine. This atomizes the fuel better (breaks it down into tinier droplets), which means more of it gets burned, which translates to more power for your engine. It also results in cleaner emissions.
Fuel injectors are precision instruments. They have to deliver the right amount of fuel at exactly the time the pickup engine needs it. They are also engineered to inject fuel with a specific spray pattern. This spray pattern allows for maximum fuel efficiency and proper atomization. Direct injection engines require a much higher degree of precision than conventional engines. For this reason, they are equipped with more sophisticated computers.
When fuel injectors get dirty, their precision drops off. The spray pattern won’t be precise, and the timing of fuel delivery may be off. This decreases fuel efficiency and gas mileage as well as delivering less power to the engine.
Marlborough motorists should understand that fuel injectors are not cheap to replace. Direct injection fuel injectors are even more costly. And we’re talking a mortgage payment to buy a set of new fuel injectors for a diesel engine.
So keeping your fuel injectors clean is just good auto advice. The best way to do this is to change your air and fuel filters regularly and practice other habits of good car care and preventive maintenance. Cleaning additives in your fuel can also help.
If you do end up with gum or varnish in your fuel system, you’ll need a professional fuel system cleaning. This will clean out your whole system, including the injectors. The good news is that with proper maintenance, Marlborough auto owners will enjoy better fuel economy and their fuel injectors will last for a long time.
