Belt Tensioners

Your Mitsubishi has a belt tensioner working in sync with your serpentine belt to keep your engine parts working correctly. It is a pulley mounted on a spring mechanism that helps to keep tension on the engine belts. Your serpentine belt is what keeps your alternator, power steering, and other components are working perfectly. The belt tensioner makes sure that there is enough tension for the serpentine belt to move the pulleys for the engine components correctly. If the tensioner wears out, then the serpentine belt will not be able to function properly. If there are problems with the belt tensioner, it can cause problems with many different parts of the vehicles affected by the other belts in the engine. If you find that there is unusual belt wear in your vehicle, or you hear squeaking noises, it could be due to the belt tensioner. If you need a new belt tensioner, you will want to make sure that you are choosing an option that is right for your model, and that you have quality OEM parts. The OEM parts are designed specifically for your Mitsubishi. We have a wealth of options for belt tensioners available to you. Shop replacement parts here to find what you need.
