Your serpentine belt drives critical engine accessories like your alternator, air conditioning compressor, and power steering. In some vehicles it may also power the power brakes or water pump. The serpentine belt is powered by the engine and winds around pulleys and the accessories. Some autos have two serpentine belts.

The serpentine belt, the belt tensioner (which maintains the appropriate tension on the belt) and the idler pulleys are together known as the accessory drive system.

Now your serpentine belt and the belt tensioner will just wear out over time – that’s why your auto maker has a scheduled belt replacement interval. The team at Poway Auto Repair in Poway can survey your serpentine belt for wear and get it replaced if it’s time.
