Robert was amazing. Really communicative and efficient. He is also great to chat with on a personal level. He worked on my 1995 BMW m3 for a routine oil and spark plug change and demonstrated his advance knowledge working on European cars. You can tell he is very experienced. I definitely recommend him and look forward to working with him in the future.

Patrick is a great guy and really knows his stuff. Yourmechanic.com rips you a new one on parts and labor but i guess you pay for not having the headache. I paid 370 labor for 3 hours and 255 for parts that go for 65 bucks on parksgeek.com and even cheaper on a few other sites but for original bmw parts it is 65 and they charged 255. Fyi. If it can wait a couple days, buy the parts first

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.
