The serpentine belt is the only belt on the car. It is what drives all the ancillary

devices IE: the alternator, Power Steering pump, water pump and the AC compressor.

If this belt breaks, you're dead in the water. It's a good idea to check it regularly for

cracks/cuts/damage and replace if necessary.

Before you take the belt off the car, be sure that you have a diagram of it's routing. There is usually a sticker somewhere under the hood that shows this. If your sticker is missing, make a sketch of the belt routing.

To loosen the belt for removal/replacement, there is a spring loaded idler pulley that the belt runs around. On my '96, it's down and to the rear of the alternator. It rotates forward to put some slack in the belt.
