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 impedes the accessories from spinning properly, leading to premature wear and noise.
Your auto manufacturer 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 honest Marshalls Automotive service specialist can review your system and let you know if it’s time for a replacement.

The primary job of the serpentine belt is to provide essential traction to spin the accessories. As the belt wears it loses some of its grip and the accessories may not spin at ideal speeds. For example, if your alternator doesn’t spin fast enough, the battery will not completely recharge while you’re driving and you could end up stranded with a dead battery.
In short, a worn serpentine belt will stress all of the accessories it powers leading to premature wear and possible early replacement. When as little as 5% of belt material is lost, the serpentine belt cannot provide the proper traction for the accessories. Your honest Marshalls Automotive technician can check your belt for excessive wear and replace your serpentine belt system if it’s excessively worn.
