Category: Serpentine Belt

The primary job of the serpentine belt is to provide vital traction to spin the accessories. As the belt wears it loses some of its grip and the accessories may not spin at best 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 reliable Certified Auto Specialists technician can review your belt for excessive wear and replace your serpentine belt system if it’s excessively worn.

The serpentine belt tensioner applies pressure to the serpentine belt, maintaining ideal 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 vehicle 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 car might have. Your reliable Certified Auto Specialists service professional can review your system and let you know if it’s time for a replacement.
