Belt Replacement

Every vehicle on the road has aserpentine-like belt running through it suspended by various pulleys. It isessential for driving main vehicle components such as the alternator and airconditioning compressor. If you know where to look, you can even inspect thebelt for yourself by looking at the front end of the engine where it is usuallymounted externally. The accessory belt used to be constructed of neoprene, butsince the late 1990’s they started to construct new belts with ethylene propylene diene monomer (EPDM belts asthey are more commonly called). These EPDM belts are much more durable and longlasting, however like all things they do eventuallywear out and need to be replaced.
