The serpentine belt tensioner applies pressure to the serpentine belt, maintaining best tension to drive the accessories like the alternator and A/C compressor. The service life of the belt tensioner is the same as the belt itself, so they should always be replaced together. A worn tensioner prohibits the accessories from spinning properly, leading to premature wear and noise.
Your auto maker has a recommended mileage interval for serpentine belt replacement. A complete accessory drive system service replaces the serpentine belt, the belt tensioner and any idler pulleys your auto might have. Your friendly and honest Schaumburg Automedics tech can inspect your system and let you know if it’s time for a replacement.
Your serpentine belt drives vital 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 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 Schaumburg Automedics in Schaumburg can review your serpentine belt for wear and get it replaced if it’s time.
