Product Information
Keeps proper tension on timing belt, should be replaced every timing belt job (4 years/50,000 miles)
This tensioner is responsible for maintaining constant tension on the timing belt. With age the bearing can wear out causing squeaks or the tensioner itself is failing. We recommend replacing this tensioner when installing a new timing belt for best performance and service life.
INA is an OEM supplier to BMW, timing belt tensioners are no longer available directly from BMW.
Engine Timing Belt Tensioner
Timing belt tensioners are typically replaced at the same time as replacing your timing belt. The tensioner exists to provide the proper tension against the timing belt and the components it revolves around. Tensioners are available in both mechanical and hydraulic variations.
