The major parts of your engine are generally run by belts. The belts are easy to forget about — they do not require attention as often as oil changes — however they are incredibly essential. Knowing how to care for engines is incredibly important – so how do you do it?

The basics of a belt
Most belts in vehicles are made from rubber or a combination of rubber and plastic. Rather than just snapping, belts will usually crack, decay, or wear. Belts can be prone to breaking or wearing out because of the conditions they’re used under. Belts generally run the cooling system, alternator, and accessories in a vehicle. Older engines used separate belts to run each component. A single "serpentine" belt generally runs anything in a newer engine.
Switching out the belts
A belt that squeaks or squeals means that it is stretching out. Every time you check your oil or take your car to the mechanic, you need to have your belts checked. Replace the belts all at once – if one is wearing out, replace them all. With basic car experience, replacing a belt is easy. First, copy down the diagram of how the belt runs around the engine. Remove the tension from the belt before you remove it. Put the new belt in the engine and re-tighten the tension.
Should you dress the belt?
Some mechanics claim that you need to "dress" the belt – lubricate it with a spray – to help it last. This theory only type of works most of the time. For a short time, if you dress a belt, it will get quieter. Remember, though, that a belt making noise is a warning that something is going wrong. You should only dress a belt for temporary silence while you get your car to the mechanic.
