These days many people in the Dupo area are really committed to making their cars last a long time. First thing: you’ve got to start with what you’ve got. It’d be ideal if people started with a brand new car, never missed a scheduled service item, paid attention to the severe service maintenance schedule and had regular inspections. But if you’ve had the vehicle for a while, or bought it used, its maintenance history is what it is; and that’s where you start.

Go through the maintenance schedule for your pickup and see what’s been done and when. Have your Marlborough service advisor at Carsmart Auto Service do an inspection and come up with a list of stuff that needs to be done. Review the list and prioritize the work, talk about budget and make a plan to get caught up.

Making a plan is so important. Suppose you go in for an oil change and learn you need your cooling system serviced, a transmission service and are coming up on a timing belt replacement in the next 5,000 miles. You might be pretty overwhelmed.

To make it even more stressful, these are all very important systems that are expensive to repair if there’s a failure. In consultation with your Marlborough service advisor, you might decide to take care of the transmission on this visit, set an appointment for the cooling system service next month and get an estimate for the timing belt replacement so you’ll be prepared for it in a few months.

Having a plan for taking care of these important services will set your mind at ease.

Clean Air for Your Engine: A New Engine Air Filter at Carsmart Auto Service

All of us Marlborough car owners know we have to get the oil changed in our pickups periodically. That’s just part of good car care. But when Dupo service advisors change your oil, they also usually inspect your air filter. That’s why they sometimes let you know that your air filter needs to be changed before releasing your pickup.

Don’t just chock this up to trying to sell you something else. Fenton drivers really do need to change their air filter when it gets dirty. You can check your owner’s manual to see how often your air filter should need to be changed, but remember, if you live in an area in MO with poor air quality, or if you drive a lot or drive under harsh conditions in the Dupo area, you may need to change that filter more often than is recommended.

Changing an air filter isn’t guesswork. If a filter’s dirty, it needs to be replaced. Air filters aren’t very expensive at Carsmart Auto Service in Marlborough. But the problems they cause if Marlborough auto owners don’t change them can get to be costly.

For every gallon of gas your pickup burns, it needs 12,000 gallons of air. Clean filters allow better airflow into your engine, which means that your engine will get more air more quickly. That means your pickup engine runs more efficiently.

Dirty air filters cut airflow to your engine. All the debris in the filter clogs up the spaces the air needs to pass through to get to the engine. This dirty air can damage costly electronic components.

If you are in tune with your pickup, you’ll notice a difference when you change a really dirty air filter for a clean one. Your pickup may actually purr for you again. Its performance improves when it has a new, clean filter. So remember, changing your air filter is one of the most vital elements of preventive maintenance. At Carsmart Auto Service, it’s inexpensive, it’s effective, and it’s essential.

Fuel Saving Tip: Car Weight And Your MO Driving

Weight is the enemy of fuel economy. Everyone from here to Fenton knows this makes sense.

Some of us in the Fenton area carry a bunch of unnecessary weight, and I’m not talkin’ what you see in the mirror.

pickup Weight Guys; sports equipment and tools. Ladies; well, just take a look around the passenger compartment and trunk. I think my car has about forty-five pounds of French fries on the floor.

All that extra weight wastes gas as you drive between here and Fenton, and everywhere else.

Lose the junk and save some money.

…And you really only need one of those spare tires.

Watching Your Check Engine Light

Did you know that most of the cars driving around Marlborough, MO carry more computer power than the Apollo 121 Lunar Module that landed on the moon in 1969?

New cars sold in the Dupo area have as many as twelve networked computers and over five miles (eight kilometers) of wiring. In fact, for the last decade or so, auto computers have been controlling about 85 percent of your vehicle’s functions.

Cars have sensors for manifold air temperature, coolant temperature, manifold air pressure, airflow, throttle position, vehicle speed and oxygen content. All of this electronic wizardry is pretty complicated. So how do Marlborough motorists know when there is a problem?

It’s simple; the Check Engine light comes on. The computer monitors all the sensors and uses that information to decide what to adjust such as the fuel mix, spark timing and idle speed. In addition, the computer monitors its own circuits. When it finds a fault, it turns on the Check Engine light and stores a trouble code in the computer.

It can be pretty disturbing for Marlborough motorists when the Check Engine light comes on. We wonder just how urgent it is. Generally speaking, it is not critical like a temperature or oil pressure light. When you get one of those it means STOP NOW! When the Check Engine light shows up, you should come in to Carsmart Auto Service in Marlborough to find out what the matter is as soon as possible.

Since 1996, there has been a strong emissions control component to the Check Engine diagnostic. But if your Check Engine light flashes on and off, you know that it is more urgent and you need to get it checked immediately to prevent damage. You should slow down and avoid towing or heavy loads until you can get it checked out.

Your courteous Carsmart Auto Service technician has special diagnostic equipment that will retrieve the trouble code from the computer and help him determine what is wrong. From there, we can fix it and get you back on the road.

Stop by if you’re check engine light is on.

How Your Check Engine Light Works

Have you ever had an experience like this in Marlborough MO? You drive through the one of those automatic car washes. When you get to the end, where the dryer is blowing, your check engine light started flashing!

You fear the worst, but within a block or two, the light stopped flashing, but stayed on. By the next day, the light was off.

You wonder; “What was going on?” Well, it’s actually a good lesson in how the Check Engine light works.

Your air intake system has a sensor that measures how much air is coming through it. When you went under the high-speed dryer, all that air was blasting past the sensor. Your engine computer was saying, there shouldn’t be that much air when the engine is just idling. Something’s wrong. Whatever’s wrong could cause some serious engine damage.

Warning, warning! It flashes the check engine light, to alert you to take immediate action.

It stopped flashing because once you were out from under the dryer, the airflow returned to normal. Now the engine control computer says the danger is past, but I’m still concerned, I’ll keep this light on for now.

Then the Check Engine Light goes off in a day or two.

The condition never did recur, so the computer says whatever it was, it’s gone now. The danger is past, I’ll turn that light off.

Now a flashing check engine light is serious. You need to get it into our Marlborough MO shop as soon as possible. But if it stops flashing, so you have time to see if the problem will clear itself or if you need to get it checked. How does the computer know when to clear itself?

Think of it this way. The engine control computer is the brain that can make adjustments to manage the engine. Things like alter the air to fuel mix, spark advance, and so on. The computer relies on a series of sensors to get the information it needs to make decisions on what to do.

The computer knows what readings are in a normal range for various conditions. Get out of range, and it logs a trouble code and lights up the check engine warning.

The computer will then try to make adjustments if it can. If the computer can’t compensate for the problem, the check engine light stays on.

The computer logs a trouble code. Some people think the code will tell the technician exactly what’s wrong?

Actually, the code will tell the technician what sensor reading is out of parameters. It can’t really tell you why, because there could be any number of causes.

Let’s say you’re feeling hot. You get your heat sensor out – a thermometer – put it under our tongue and in a minute or two you learn that you have a fever of 104 degrees.

You know your symptom – a fever – but you don’t know what’s causing it. Is it the flu, a sinus infection or appendicitis?

You need more information than just that one sensor reading. But it does give you a place to start and narrows down the possible problems.

There are reports on the internet telling you that you can just go down to an auto parts store and get them to read your trouble code or buy a cheap scan tool to do it yourself.

There are two problems with that. First, the computer stores some trouble codes in short term memory, and some in permanent memory. Each manufacturer’s computer stores generic trouble codes, but they also store codes that are specific to their brand.

A cheap, generic scan tool, like you can buy or that the auto parts store uses, doesn’t have the ability to retrieve long-term storage or manufacturer specific codes. Your Marlborough MO service center has spent a lot of money on high-end scan tools and software to do a deep retrieval of information from your engine control computer.

The second problem is that once you’ve got the information, do you know what to do with it? For example, a very common trouble code comes up when the reading on the oxygen sensor is out of whack.

So the common solution is for the auto parts store to sell you a new oxygen sensor, which are not cheap, and send you off on your way. Now your oxygen sensor may indeed have been bad and needed replacing. But the error code could have come from any of a dozen of other problems.

How do you know the right solution? Back to the fever analogy, do you need surgery or an aspirin? Leave it to the pros at Carsmart Auto Service. Give us a call at 314.968.9496 and let us help you resolve your check engine light issue.
