Drive Belt Tensioners, Idlers & Dampers

The belt tensioner is a spring-loaded rotating pulley which stops the timing belt from slackening or misaligning. Some engines come with manual tensioners and others with automatic examples. The idler pulley routes the drive belt and allows it to move in a certain direction. Meanwhile, the damper works closely with the tensioner to prevent uneven rotation. Like any part of your car, tensioners, idlers and dampers do not last forever. Cracks or chips can appear as a result of constant exposure to heavy forces, heat and flying debris. Such exposure may even cause the pulleys to seize up completely. To stop your engine grinding to a halt and to avoid costly repairs, buy cheap tensioners, idlers, or dampers from Car Parts 4 Less.
