Belt tensioners are essential components of the engine system for heavy duty trucks, medium duty trucks and light duty trucks. They maintain the proper tension of the drive belts that power various accessories, such as the alternator, water pump, air conditioning compressor and power steering pump. Belt tensioners also help to reduce belt noise, vibration and slippage, which can affect the performance and lifespan of the engine and its parts.
