Folsom Autotech Maintenance Tips: The Belt Goes On

Posted January 31, 2012 12:00 PM

drive All Folsom service advisors know that without the alternator, the battery will go dead in a few miles.

The serpentine belt may also run the pumps for both the power steering and power brakes. And on many vehicles, the serpentine belt powers the water pump. The water pump circulates coolant through the engine to keep it within normal operating temperatures. (On some vehicles, the water pump is powered by the timing belt instead of the serpentine belt.)

So you can see the serpentine belt does a lot of work. And it if breaks, it affects a lot of systems. That's why your vehicle manufacturer and your service advisor at Folsom Autotech have recommended that it be changed every so often so that it doesn't fail.

Your friendly and knowledgeable Folsom Autotech service advisor can perform a visual inspection of the belt to see if it has any cracks that signal the belt could fail soon and will measure the amount of belt material to make sure there is enough.

Your serpentine belt works in tandem with a spring loaded pulley attached to the engine called the tensioner pulley. Its job is to make sure there's a constant tension on the serpentine belt so that it doesn't slip. The spring can become worn and no longer provide the necessary pressure to keep the belt tight. At Folsom Autotech in Folsom, we recommend that the tensioner be replaced at the same time as the serpentine belt.

Fuel Saving Tip: Tire Pressure Saves Fuel in Folsom

Posted January 24, 2012 12:00 PM



Underinflated tires waste gas for lots of folks in the Folsom area. Think how hard it is to walk in sand – you just have to work harder because of the resistance. When your tires don't have enough air in them, their rolling resistance is dramatically increased and it simply takes more gas to get from here to there.

Always check your tire pressure when you gas up at one of our local Folsom service stations. If they're low – even just a little bit – bring them up to proper pressure. There's a sticker on the inside of your driver's door that gives the manufacturer's recommended tire pressure.

And don't rely on your tire pressure monitoring system to alert you to when you need more air. The TPMS system is set to warn you when pressure drops 20 percent below recommendations. That's severely underinflated and you needed more air a long time ago. And if you have a slow leak – get it fixed right away at Folsom Autotech.

Get some air and save some gas.

How Your Check Engine Light Works

Posted January 17, 2012 12:00 PM



Have you ever had an experience like this in Folsom, California? 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 starts flashing!

You fear the worst, but within a block or two, the light stops flashing, but stays on. By the next day, the light is 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 Folsom Autotech as soon as possible. But if it stops flashing you can wait a few days, 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 him 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 F (40 degrees C).

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 online or that the auto parts store uses, doesn't have the ability to retrieve long-term storage or manufacturer specific codes. Your Folsom, California, 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 is 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 Folsom Autotech. Give us a call and let us help you resolve your check engine light issue.

Fuel Filter Service in Folsom, California

Posted January 10, 2012 12:00 PM



There are a surprising number of small, inexpensive parts that can lead to expensive engine damage when they fail. It doesn't seem right.

Fortunately a lot of those things can be taken care of in routine maintenance. They may not be easy to remember because it is a long list, but your service center at Folsom Autotech can help you know what's scheduled to be taken care of.

Some of us in Folsom, California, really don't look forward to going in for an oil change and then getting a list of the other things the manufacturer recommends.

But automotive maintenance is all about prevention and addressing small problems before they get big. Let's take the fuel filter for example.

You may not know this but the median age for private vehicles on our Folsom, California, roads is over nine years. When vehicles get older, five years or so, they've accumulated a lot of dirt and rust in their gas tanks. If that dirt gets into the engine it can cause thousands of dollars worth of damage. So somewhere between that dirty gas tank and the price of a great vacation is the lowly fuel filter: a very inexpensive part that doesn't cost too much to replace. And your vehicle will just run better too.

A clogged fuel filter can't let enough fuel through. You might notice at first that your vehicle is running fine around town but struggles or sputters on the Folsom, California, freeway or when you accelerate. Enough fuel can't get through to meet the demands of higher speed. If it gets bad enough, your engine might just shut off or not start at all, which could be dangerous.

Some fuel filters have a bypass. When they get clogged, they allow dirty fuel to move around the filter element so dirt ends up in the engine. We've already talked about how expensive that can be.

The fuel filter is even very important for newer vehicles. The fuel is still dirty even if there isn't rust in the tank. It's just that the fuel filter will need to be changed more frequently as the vehicle gets older.

How often should you change your fuel filter? Check your owner's manual. Your Folsom, California, service advisor at Folsom Autotech can tell you as well. It's usually around 30,000 miles (50,000 kilometers) or so. Ask if it's time for a full fuel system cleaning as well. They often go hand in hand.

It's good to know that your Folsom, California, service center has your back. When you're motivated to maintain your vehicle's performance and to reduce operating costs, you'll think of Folsom Autotech as your ally - and maybe even your memory.

Differential Service in Folsom, California - What You Need to Know

Posted January 3, 2012 12:00 PM

Scratching your head? Don't worry, if you don't know what a differential is – you will in a moment. That fact is that if you drive a car anywhere in Folsom, California, you have a differential. Whether your vehicle is front-wheel drive, rear-wheel drive or four-wheel drive, you have a differential. Some Folsom vehicles might even have two or three.

Not surprisingly, a differential's job is to compensate for differences; specifically, they're the differences in wheel speed when turning. For instance, imagine taking a corner near your Folsom, California, home. Your inside wheel has a shorter distance to travel than the outside wheel as you turn the corner. That means that your outside wheel has to turn faster to keep pace with the inside wheel.

The differential allows the wheels to turn at different speeds while still providing power to your vehicle. Without a differential, Folsom residents' tires would scrub and hop along the pavement during turns like the early cars.

Ever noticed the big bulge in the middle of the rear axle on trucks? That's the differential. Rear-wheel drive vehicles have a differential in back. Most four-wheel drive trucks and SUVs will also have a similar differential on the front axle. A front-wheel drive vehicle's differential is called a transaxle because it combines the differential and transmission in one unit. An all-wheel drive vehicle will have a differential or transfer case that adjusts for speed differences between the front and rear drive wheels.

It can seem a little complex to some Folsom drivers - but you can see that all of the engine's power is routed through your differentials. They're strong enough to handle the work, but- we've said it before - they need to be properly lubricated in order to stay strong. So from time to time, you need to schedule a differential service in Folsom at Folsom Autotech. The used fluid is drained and replaced with clean fluid. Some advise certain differentials to have special additives installed.

Get your differential serviced at Folsom Autotech in Folsom.
