This pulley is mounted along with the hydraulic belt tensioner but can be replaced on its own. It is used for the main drive belt on the M50-M54 family engines (M50, M50TU, M52, S52, M52TU, M54, M56, and S54 engines). This is the same belt that covers the water pump/alternator/power steering systems. Replacement is a very easy procedure (requires fan removal) and will have your engine purring in no time. Belt replacement is strongly recommended at the same time. If you have a mechanical belt tensioner, the pulley can only be replaced with a new tensioner.

This high-quality replacement from Bremmen Parts is designed for exact fitment on your BMW. Whether you're looking to complete much-needed preventative maintenance, or replacing a failed roller, choose this component from Bremmen Parts for a lasting repair.

Keeping all of your belts tight is imperative to making everything in your vehicle functioning. If your A/C belt tensioner pulley is not keeping enough tension on your belt, your entire A/C system won't work as effectively. A usual sign that your tensioner needs replacing is if your belt keeps slipping causing the system to "squeal".
