Tensioner for BMW 3 Series F30 (2012+)

Clear BMW chassis

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.

Accessory belt tensioners provide tension to the belt drive system, ensuring the belt is able to properly turn engine accessories without slipping. If your tensioner has failed, replace it with a brand-new unit to ensure proper water pump and alternator functionality.
