Belt Tensioners

The belts in your vehicle require precise timing and movement to achieve their goals. A serpentine or timing belt tensioner keeps the appropriate amount of slack, or tension, on the belt, keeping the parts moving in unison. A belt tensioner also protects other components from unnecessary stress. If your belt tensioners fail, your timing and serpentine belts won't function properly, which can lead to serious damage and repairs. Like any other parts of your car, the belt tensioner isn't invincible to damage. If the tensioner is starting to fail, you might start to hear loud noises coming from the tensioner or one of the belts. A lack of tension on your belts can result in squealing or squeaking noises. Unusual belt wear and tear can also be something that stems from a problem with the belt tensioner. Don't ignore problems with your tensioner! Protect the sensitive components of your car, truck, or SUV with OEM belt tensioners from My Audi Parts Now. It's important to get OEM belt tensioners that are made with your specific vehicle in mind so they will install properly. We have those here, so browse our selection below!
