BMW 5-Series E39 (1996-2003) Camshafts & Timing Chains - Timing Belt Tensioners

Timing Belts and Tensioners

The tolerances between the valves and pistons on some engines are very narrow, and this potentially disastrous dance between parts is all kept in harmony by the timing belt and tensioners. Make sure yours are all in proper working shape so you can continue to hear sweet sounds from your engine for years to come.

Timing Belt Tensioners

Timing belt tensioners are used to keep a constant tension on the belts. Slippage of the belt can result in catastrophic contact between the valves and pistons.
