Excellent in service, knowledge and pricing. We had an issue with out 2000 chevy Taho, and for years I could not get a dealer or other small shops in loveland to tell us why we heard a knock in the lower bottom side of the engine block on this 5.3 liter Vorteck. Finally they worked their experience and flushed out the engine and it sounds like a champ. It was so important to us because we wanted to give this to our daughter on her 16th birthday and we heard from another mechanic that we needed to sell the suv or buy a new engine.
