Needed my front struts replaced. Shaun was originally unable to remove the springs from the strut due to the spring's high tension - he took the shocks back to his place where he had an air compressor and finished the job before I got out of work. All throughout this he remained intention about staying communicative - very professional! I'd say - a good job! Car's working fine now.

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.
