Awesome experience!! Chris was great!! I was extremely satisfied with his service. I would recommend him to family and friends. Besides delivering a new battery and installing it, He checked all the fluid levels, checked the tire pressure and made sure all the the malfunction lights went away. He was very professional, knowledgable and friendly.The final bill was less than I was quoted, because he gave me a $20.00 discount.I asked for his card so that I could request him if I need YourMechanic services again. Love this company!!!

All about Drive Belt Tensioner Replacement

A Drive Belt Tensioner is a pulley mounted to either a spring mechanism or to an adjustable pivot point that is used to keep constant tension on your serpentine belt. That is the big long belt in the front of your engine. The tensioner rides on the outside surface of the belt to put pressure, or tension, on the belt and against the pulleys that drive things like the alternator, power steering, air conditioner, etc.
