He seems professional. I paid for the lights to be addressed and they are all still on including a low engine oil light. He said he would return to check it out further after his next appointment but I did not hear back from him. I was told by BMW that the power steering fluid needs to be drained, flushed and refilled. He sucked it out with a hose twice and this will not ensure that the oil that was accidentally placed in there would be completely removed. I am no mechanic but I am going off of what BMW told me. I wanted to get a lot more work done. I want all the lights to be addressed and fixed so I started with the check engine lights to be looked at and not just reset. I want everything to be fixed. Thank you

Jason was very knowledgeable and deliberate. He did an inspection to verify the complicated problem and the proceeded to acquire the OEM part required and credited me the inspection fee as he completed the repair. I would highly recommend Jason on all types of repairs and service.

This is 2nd time Jay has worked on my BMW, he is reliable and explained everything to me. He replaced front brake pads and rotors and did an oil change. So convenient having work done at my house by an experienced, reliable and friendly mechanic. Will be making an appointment for back brakes very soon. Thanks Jay.

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.
