A belt tensioner is an automotive component that maintains proper tension in the serpentine belt, ensuring optimal performance and longevity of the engine's accessories. The tensioner works by adjusting the belt's tension as it wears, preventing slippage and maintaining efficient power transfer to accessories such as the alternator, air conditioning compressor, and power steering pump. Regular maintenance and inspection of the belt tensioner are crucial for a well-functioning vehicle.
