Clear BMW chassis

Please ensure your correct model is selected

The belt tensioner is responsible for keeping proper tension on the belt at all times and during all running conditions. When the tensioner ages, it loses some of the spring tension and can allow the belt to slip if left unchecked. Turner Motorsport carries Genuine BMW and high quality aftermarket options to get you back on the road in no time.

If your water pump or alternator belt tensioner has failed because of the pulley or bearing, this replacement pulley is all you need to get your BMW back on the road! BMW and other brands usually sell the tensioner with the metal arm included, which increases the cost, even though the arm often doesn't need replacement. This OEM replacement is a much more affordable option, saving you $150 or more compared to the Genuine BMW tensioner.
