The serpentine belt tensioner applies pressure to the belt, maintaining the right tension to drive the accessories like the alternator and A/C compressor. 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.
Your vehicle manufacturer has a recommended mileage interval for your belt replacement.
