This is the BEST service I have ever found....the MBZ dealer was a RIP OFF and if you went to a shop you had to get a ride and it was still expensive.....I work from home and it's the perfect fit. I wish you guys mucho success. I'm referring everyone I know!!! Laura Mattos

Fantastic mechanic. The cost of changing the oil at a Mercedes dealership was $283.00. He saved me over $190.00. He showed up on time, with a great smile. He sure knows his business. Did a great job!!!!!

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.
