The basics of a belt

Most belts in automobiles are made from rubber or a combination of rubber and plastic. This combination of materials has a tendency to wear out, crack and decay. The tension the belts are under combined with the hot-and-cold conditions they typically run under means that they will stretch and break. Belts are usually used to run everything from the fan to the cooling system. In some cars, you will find 3 or four separate belts that run each part. Most engines built after the late '80s use a single "serpentine" belt.

Changing out your own belts

When a belt starts to squeal or screech, it means that it is stretching out. Have your belts checked each time you take your car in for service. If you see a belt that is cracking or splitting, it is time to replace them all. It is relatively easy to replace a belt if you have basic maintenance experience. First, discover the diagram of the belt and copy it down. Loosen up the tension within the belts, then remove them. Tighten up the tension after you put the new belt in the engine.

Thinking about dressing the belt?

There is a theory that “dressing” a belt — lubricating it with a specialty spray or liquid — can help it last longer. This is only partially true. For a short time, if you dress a belt, it will get quieter. Before you dress a belt, you need to bear in mind a belt making noise is a warning. The only time you should ever dress your belt is if you’re trying to keep things more quiet while you are on your way to the mechanic.
