Belt Tensioner - B3925182
An automotive belt tensioner is a component that maintains proper tension on the engine’s serpentine or timing belt. It consists of a pulley and a spring mechanism, which automatically adjusts to variations in belt length and engine movement. This ensures optimal performance of accessories like the alternator, power steering pump, and water pump. A properly functioning tensioner reduces wear on the belt and helps prevent slippage, contributing to overall engine efficiency and reliability.
A Tensioner maintains the correct amount of tension on the belt at all times throughout its duty cycle. It also helps protect other components such as the alternator and water pump from undue stress and premature failure. In addition, a tensioner is a relatively inexpensive part to replace.
