Automotive Tips from Auto Lab Troy: Serpentine Belt Tensioner
October 31, 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 Auto Lab Troy 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 Troy 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 Auto Lab Troy service advisor can inspect your system and let you know if it’s time for a replacement.
