BMW E60 Tensioner Pulley Replacement – 2004-2010 5 Series – M54 6 Cylinder

Keeping all of your belts tight is imperative to keeping everything in your vehicle functional. 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".

If the belt in your vehicle recently fell off it might be because the tensioner in your vehicle is broken. To prevent from this happening again replace your tensioner today with this direct replacement.

This pulley controls the water pump and alternator belt. Commonly the cause of bearing noise underhood.

Accessory belts keep everything turning off of the crank pulley. AC compressors rely on this belt to keep everything working properly. If your drive belt is getting old, cracking, glazing, or squeaking, replace it. It's easy to see when the belts are beginning to wear. Visually, the belt will begin to glaze on the underside, making it far less effective. Cracks can appear on the back of the belt from “dry rot” caused by exposure to engine heat or age. Squealing is common on worn belts which basically means that the belt is slipping on pulleys. In either case, your vehicle needs a new belt.
