Alternator Belts


An alternator Belt drives the engine's alternator. Keeping the car's battery charged is the job of an alternator. Without the alternator Belt the battery would die after a short amount of driving. The spinning is made possible by the Alternator Belt that runs from the pulley on the alternator to the crank-shaft.

The type of the Belt around the alternator depends solely on the make of the vehicle. Older cars are fitted with a Cogged Belt for the alternator, while newer cars use Poly-V Belts as an alternator Belt.
