Auxiliary belt

The auxiliary belt, also known as serpentine belt, auxiliary drive belt, aux belt, fan belt, alternator belt accessory drive belt, and v-ribbed belt – is basically the replacement of the V-belt in modern cars. The serpentine belt has the task to power the alternator and water pump. In modern cars the aux belt also drives the air-conditioning compressor and the power steering pump. It gets its snake-like name 'serpentine belt' from the way it twists around multiple pulleys – to perform all of these jobs. The serpentine belt is a moving part and therefore subject to wear and tear. Does the auxiliary belt squeak? Then check what the cause is. It is possible that the aux belt has dried out and therefore needs to be replaced. You can replace a multi belt yourself and you can get yours at Winparts.
