Automotive Tips from Commerce Auto Repair: Serpentine Belt Tensioner

January 3, 2017

The serpentine belt tensioner applies pressure to the serpentine belt, maintaining optimal tension to drive the accessories like the alternator and A/C compressor. At Commerce Auto Repair we know that the service life of the belt tensioner is the same as the belt itself, so they should always be replaced together. A worn tensioner prevents the accessories from spinning properly, leading to premature wear and noise for Commerce drivers.

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 friendly and professional Commerce Auto Repair service advisor can inspect your system and let you know if it’s time for a replacement.
