Tensioner for BMW X Series F25 (2011+)

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.

Pulleys begin to squeak once they are reaching the end of their life span and the tensioners can fail, no longer applying enough tension to the accessory belt. If not replaced, tese can seize up and lead to a long host of problems that would leave you stranded on the side of the road. Prevent this with routine maintenance and replace your belts and pulleys every 50,000 miles to ensure continued reliability.
