Automotive Tips from Commerce Auto Repair: Serpentine Belt Overview
February 29, 2016
The technicians at Commerce Auto Repair know your serpentine belt drives important engine accessories like your alternator, air conditioning compressor, and power steering. In some cars 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 cars in Commerce 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 vehicle manufacturer has a scheduled belt replacement interval. The team at Commerce Auto Repair in Commerce can inspect your serpentine belt for wear and get it replaced if it’s time.
