Inspect belt for fraying. If fraying has occurred, ensure belt and tensioner are aligned properly. If tensioner has reached its limit of travel, belt is excessively stretched and replacement of belt is required. If excessive noise is noticed from tensioner or idler, check for possible bearing failure. Belt tension adjustment is not required on vehicles with automatic belt tensioners. DO NOT apply belt dressing or any other additive to belt(s). Ensure belts are properly installed
