If you’ve ever heard a squealing sound under your hood, chances are it was your serpentine belt. Your serpentine belt is a long belt that’s driven by your engine. It winds around several accessories that power important automotive systems in your car. Let’s go over them.

First, the serpentine belt drives your air conditioning system. It spins the compressor that makes the cool air that takes the edge off the summer heat in Apple Valley.

Next, the belt powers the alternator. The alternator creates electricity that’s used by your car’s electrical systems and also charges your car battery. 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 (some are electric) and power brakes (some use vacuum boost).

And, on most cars, the serpentine belt powers the water pump. The water pump circulates coolant through the engine to keep it within normal operating temperatures. On some Apple Valley cars, the water pump is powered by the timing belt instead of the serpentine belt.

When they understand what it does, Apple Valley drivers realize that if it breaks, it affects a lot of systems. That’s why manufacturers have recommended that it be changed every so often so that it doesn’t fail.

At Valley Auto Care, we can perform a visual inspection of the belt to see if it has any cracks that signal the belt could fail soon. If the belt has more than three or four cracks every 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.

If it has lost a significant thickness, it also needs to be replaced. There’s a special 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 Valley Auto Care, we recommend that the tensioner be replaced at the same time as the serpentine belt.

As mentioned, a squealing sound could be a sign that the serpentine belt needs to be replaced. It may be loose if you hear a slow, slapping sound when idling your car.

All in all, the serpentine belt’s an important part for the function of your car. And it’s not that expensive to replace at Valley Auto Care – so it’s good to do so before it fails.

Here's a travel tip that'll I'll bet you didn't know, and, it might keep you safer...

The average American commuter in Minnesota spends two and a half hours daily in their car.

The government says a hundred thousand auto accidents yearly are caused by drivers who fall asleep at the wheel. (Aggressive driving is the number one traffic safety concern.)

So what does this have to do with how your car smells while you're driving around Minnesota?

Well, which scent did you think makes drivers more alert?

Is it:

• A. Strawberry
• B. New Car
• C. Pine
• D. Warm Vanilla Breeze

It's C. Drivers are more alert and have less fatigue with pine scent in the car, according to AroMetrics.

And, drivers were less angry with overall improved driving performance with strawberry and pine scents.

And you thought they just smelled nice.

Today we’re going to be talking about serpentine belts for our Apple Valley Minnesota customers. Let’s start by talking about the accessories that are driven by the serpentine belt. First is the alternator. That’s the device that makes electricity to power the vehicle and recharge the battery. Then there’s the air conditioning compressor that makes cool air for you while you're driving around Apple Valley Minnesota in the summer.

The power steering and power brake pumps are driven by the serpentine belt in most vehicles. Those pumps make the pressure that assists your steering and braking.

In many vehicles, the water pump is driven by the serpentine belt. The water pump is what circulates the coolant that protects your engine. In some cars around Apple Valley Minnesota, the water pump is driven by the timing belt.

The radiator cooling fans on some vehicles are also driven by the serpentine belt. Some have separate electric motors. That’s really a lot of work for one belt.

But modern engine design has a single belt that snakes around the front of the engine and drives most if not all of these accessories. Serpentine belts do a lot of work, but they’re tough and can last for thousands of miles.

Just how long will they last? That’ll vary for each individual car in the Apple Valley Minnesota area. Your manufacturer will have a recommendation for when it should be changed, but it could need it sooner. The good news is that a visual inspection can reveal a belt that’s getting close to failing.

Valley Auto Care can look at the belt: if it has more than three or four cracks per inch it needs to be replaced. A deep crack that’s more than half the depth of the belt - replace. Frayed, missing pieces, a shiny glazed look? It’s out of there.

What’s involved in replacing the belt? First the old belt is removed. Then a new one is fitted around all the pulleys for the accessories and the drive. There’s a special pulley called a tensioner.

This pulley is mounted to the engine block with a spring loaded arm. Its job is to apply the correct amount of tension to the belt to keep it from getting loose and maybe slipping off. Because the spring in the tensioner pulley wears out, AutoNetTV recommends replacing them at the same time as the belt. It just makes sense.

What are the warning signs that there’s a problem with the serpentine belt? You may hear a squealing sound from under the hood when accelerating around our Apple Valley Minnesota streets. A loose belt might give you a slow, slapping sound.

What do you do if your belt breaks? If you’ve actually had that happen on our local Apple Valley Minnesota freeway, it can be a little scary. Often the first thing you notice is that you have no power steering or power brakes. Don’t panic – you can still steer and brake, but you’ll have to do the work. It’ll be harder to steer and you’ll need more time and effort to stop, so plan accordingly.

Your dashboard will light up will all kinds of warnings. You’ll see a warning about your cooling system if you have a water pump that’s driven by the serpentine belt. This is very critical because without your cooling system working, your engine will overheat. If you don’t stop you’ll have massive engine damage, maybe to the point that you need a new engine. Pull over as quickly as you safely can. Open your windows and turn the heater on full blast to provide a little engine cooling and pulled over as soon as possible.

The battery light will come on because the alternator isn’t working. If your car’s water pump isn’t driven by the serpentine belt, you’re not in danger of overheating so you can drive a little further if necessary. But the battery will run down to the point where the car won’t run and will just shut off. You don’t want that to happen while you’re driving in our local Apple Valley Minnesota traffic.

Remember, this does not have to happen if you replace your serpentine belt on schedule. Ask your technician at Valley Auto Care to check your belts and hoses from time to time so you can take care of them if they need to be replaced prematurely.

If you're like most of us in Apple Valley, you want your car to handle well. That's the job of your suspension system.

There are different types of suspension systems, but they all work on the same basic principles. First, there are the springs, which bear the weight of the car. The most common springs are coil or leaf - although we see air springs and torsion bars more often. The springs do most of the work.

Visit our Apple Valley location for an inspection of your suspension.

But if all you had were springs, your vehicle would be bouncing around like a bobble head. That's where the shocks come in. They control the rebound of the springs and smooth out the up and down motions. They also keep the tires on the road, and you in control. Some cars use struts. Struts are a combination of shocks and springs, together in a more compact system.

Shocks wear out slowly over time, so it's hard to notice when they get badly worn. One way to tell is to look for an uneven, cupping wear on your tires. If the shock or strut is leaking fluid, it needs to be replaced. If your car feels floaty in turns or if the front end dips a lot when you stop, it is time to get your shocks checked. Your owners' manual will tell you when your shocks should be changed - it's usually between 15,000 and 30,000 miles or 24,000 and 50,000 kilometers .

When you replace a shock, be sure to replace all four. Then your car will have an even suspension and will handle much better. Talk with your service advisor about how you drive. No, not your traffic violations, but how often you carry heavy loads, tow a trailer or drive in rough terrain. If you do a bunch of that, you'll need a heavy duty shock.

Regular shocks use hydraulic fluid and air as their dampening system. Premium quality shocks and struts use compressed nitrogen gas instead of air. Gas shocks don't get air bubbles that affect the performance of regular shocks. If you do a lot of high performance driving, off-roading or just want added comfort and control, think about getting premium gas shocks or struts.

Replacing your struts may take your car out of alignment, so be sure to get an alignment at the same time. So, to smooth out the bumps on the road of life, change your shocks and struts when they need it.

The government mandates a lot of equipment on cars in Apple Valley Minnesota: emission devices and control computers, safety equipment like airbags and crash worthiness requirements. All of this is great for the Apple Valley Minnesota motoring public, but it does add quite a bit to the price of a new car.

Because new cars are more expensive, people in the Apple Valley area are driving their old cars longer. The average car is now over nine years old. Two thirds of vehicles on the road in Apple Valley have more than 75,000 miles. As cars age, their performance drops, they have difficulty idling for long periods and are more sensitive to weather extremes. Fortunately today's cars are up to the challenge – but they need a little help to keep on goin'.

Some owner's manuals don't specify service requirements at higher mileage. That doesn't mean it doesn't have to be done. In fact, it's more important than ever to stay on top of routine maintenance for cars with more than 75,000 miles.

First, just extend regular service intervals out: for instance a service that's recommended every 15,000 miles should be performed at 15,000, 30,000, 45,000 and 60,000 miles, and so on. Because of the additional stress older engines experience, the severe service maintenance schedule is more appropriate than the regular schedule – ask your service advisor. Watch for leaks – seals and gaskets dry out over time and don't hold the fluids as well as they used to.

It's also time to make sure you have a good Apple Valley Minnesota technician. There are some services and replacements that are scheduled after you put on some clicks, like timing belts, valve train adjustments, suspension, anti-lock brake service, air bags, etc. And unexpected repairs down the road are just par for the course. Check for unusual sounds, smells or the way your car feels. These could be hints that trouble's brewing. Better to catch it early before it turns into a costly repair.

And a regular wash and wax will help maintain your car's appearance. One of the things you can do to really help your high mileage vehicle is to begin using high mileage formulation fluids. There are special engine oils, coolants, and transmission and power steering fluids that are formulated for cars that have a few clicks on the old odometer.

High mileage oil is designed to condition seals and gaskets, reduce wear and avoid premature burn off. Older engines are dirtier inside – and dirty engines contaminate their oil faster. High mileage oil has special additives that clean the engine, removing sludge deposits over time. The result is less stress on the engine, better fuel economy and excellent wear protection.

Studies have even shown that using high mileage fluids early will actually prevent some of the problems of high mileage vehicles. So once you hit around 50,000 miles, consider stepping up to high mileage formulations. High mileage fluids cost a bit more than standard fluids because of the additional additives, but they can be worth their weight in gold in terms of preventing repair costs down the road. It does cost more to properly maintain a higher mileage vehicle – but it's way cheaper than a new car payment!
