Most St. Peter folks occasionally have days when they’ve got a bunch of errands to run. Yesterday was my day off and I needed to fill the gas tank, pick up some groceries at my St. Peter market, swing by the ATM and get the kids from school. I could have made four trips . . . but that would have been totally inefficient. Instead I got unusually organized and planned my stops. I hit the ATM first and got gas next. Then I went to the supermarket and picked up the kids on the way home. I was proud of my wise use of time and money.

What does this have to do with your car? Well, back in the day, each of your engine’s accessories, like the alternator and air conditioner, were powered by separate belts. A vehicle might have five or six belts. These days, vehicles have a single belt to run all the accessories. It’s called the serpentine belt. A pulley attached to the vehicle engine’s crank provides the power to turn the serpentine belt. On the engine in the video, the first accessory in line is the power steering pump, which makes it easier to steer your vehicle.

Next comes the alternator which powers the vehicle’s electrical system and charges the battery. Then the air conditioning compressor. This helps make cold air to keep you comfortable all summer long in St. Peter. Finally, we come to the belt tensioner. Its job is to apply pressure on the belt to keep it tight. Then, back home to the crank.

This is a pretty typical setup, but it can vary somewhat. In some vehicles the water pump or radiator fan or the power brakes are also run by the serpentine belt. Some even have two serpentine belts. No matter how your engine is laid out, you’re not going far without a serpentine belt. Your vehicle manufacturer has a recommended interval for replacing your belt and your Autotronics of St. Peter service technician can inspect it for damage or wear.

Several years ago, manufacturers started making serpentine belts out of a new material. It’s much more durable, but it’s harder to tell when the belt needs to be replaced. The old style belts would crack and chunks would fall off so you could easily see when you needed a new one.

On the new style belts, if the ribs wear too deep, it’s time to replace. Your Autotronics of St. Peter technician uses a simple gauge to tell when the belt is worn.

A worn belt stresses your vehicle engine’s expensive accessories and causes them to wear prematurely. So, change your serpentine belt and belt tensioner according to your manufacturer’s recommendations to extend the life of your accessories and to prevent future breakdowns.

The function of the fuel filter is pretty self-explanatory. It filters your fuel. The fuel filter is in the fuel line somewhere in between the fuel tank and the engine. Both gas and diesel vehicles around St. Peter use fuel filters.

Generally speaking there’s not a lot of dirt in our St. Peter area auto fuel supply, but there is enough that you want to screen it out. The problem actually gets worse the older your vehicle becomes. That’s because dirt, rust and other contaminants will settle out of the fuel and onto the bottom of the fuel tank. After your vehicle is five years or older, it can actually have a fair amount of sediment built up.

That just means that the fuel filter has to work harder as your vehicle ages. It’ll get clogged sooner and need to be replaced more often.

A symptom of a clogged fuel filter is that the engine sputters at highway speeds or under hard acceleration. That’s because enough fuel is getting through around town, but when you need more fuel for speed, enough just can’t get through the filter. Obviously, that could be dangerous if your car or truck can’t get enough power to get you out of harm’s way.

For just that reason, fuel filters have a bypass valve. When the filter is severely clogged, some fuel can bypass the filter all together. Of course that means that dirty, unfiltered fuel is getting through to be burned in the engine.

This dirt can then clog and damage your fuel injectors. Now injectors are not cheap to replace, so you don’t want to cause them damage just because you didn’t spend a few bucks to replace a fuel filter.

You know, in a way, the fuel filter can be the poster child for preventive maintenance. It’s a little part, it’s simple and it’s cheap to take care of. But if it’s neglected, it could lead to thousands of dollars in repair bills.

Those auto service schedules in your owner’s manual are there for a reason. If ever you don’t understand a recommended service, just ask your St. Peter service advisor at Autotronics of St. Peter. We’ll be happy to explain.

It’s important for St. Peter drivers to know battery basics. First, let’s talk about which is harder on a battery – hot or cold MN weather. Most St. Peter area drivers think it’s cold weather because that’s when we call on our batteries to have enough power to start a cold vehicle engine.

However, heat does more damage to a battery than cold. Truth is, our batteries start to die a little from day one. Keeping a full charge slows the process, which is hard with short St. Peter trips because the alternator doesn’t have time to fully recharge the battery from starting the engine. St. Peter drivers can top off the charge with a computer controlled battery charger – say, once a month in the summer and every three months during the winter.

As far as how long a battery will last, statistics show that 70% have given up the ghost within four years. By that time, they aren’t capable of taking a full charge like they used to, and your vehicle alternator has to work overtime to keep up. This causes your alternator to wear out early.

If you’re pushing 4 to 5 years on your battery, see your friendly and knowledgeable Autotronics of St. Peter service assistant for a battery test to see if it’s recommended to replace it. Not only can you avoid getting stranded with a dead battery on a MN road, but you’ll save unnecessary wear and tear on your vehicle alternator.
