Checking belt tension is a critical aspect of maintaining a vehicle’s engine performance and longevity. A belt tensioner is a mechanical device that maintains the proper tension of a drive belt, which transmits power from the engine to various accessories such as the alternator, power steering pump, and air conditioning compressor.
A loose belt can cause squealing noises, reduced efficiency, and premature wear, while an overly tight belt can put excessive strain on the belt and its components, potentially leading to breakage. Regular inspection and adjustment of belt tension are therefore essential to ensure optimal engine performance and prevent costly repairs.
