Patrick was right on time, and started working immediately. Had all the proper Mercedes approved oil, filter, gaskets etc and completed the task with no issues. Even went out of his way hooking up air compressor to put the proper air pressure in all my tires. Would highly recommend!!

Jeff changed my oil pretty quickly even though my Mercedes is a bit of a hassle to deal with. Additionally, he helped me figure out that the reason my car wasn't changing gears is most likely because it does not have enough transmission fluid. On top of that, he was very friendly and provided me with awesome customer service- and now I know exactly what I need to get services to get my car back in action!

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.
