Rocco

Rocco came to my home to check out my car since it would not start. I did not want to go through the hassle of having to tow it to a repair shop and wait around. I had a problem with my starter. With repairs like this you would think you'd have to go to a repair shop but I'm relieved I was able to have it fixed at my home from someone professional. He came and checked out my problem (which took less than an hour), provided an estimate along with how much time/labor would be involved and the next day came and made the repair. And I was able to save time without waiting around for other customers and cars ahead of mine like at a shop. I'd definitely use the service and call him again in the future :)

Theodore

I was very impressed with Theodore. I took a chance on using this mobile mechanic site and was nervous at what to expect. He came on time, did a really good inspection and made recommendations what I needed. I booked him because my driver side window was making a funny noise and I thought I needed to change the motor. He spent a good amount of time looking into the issue and explaining to me as he went along. I will highly recommend and plan on using him again.

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.
