James

James did a great job replacing my radiator. He called to see if he could come a little early which worked out great. He was very professional, cleaned everything up after he was all done. Asked if I had any question about anything on my car and gave me a few pointers about an issue I was having with my hood shocks. I will for sure be calling him again when I need any service done to my car. I have already recommended him to 3 of my friends looking to get some work done on their cars.

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.
