My 1999 Corvette had a belt that was making noise and overheating and I replaced the belt tensioner and serpentine belt but it only made it louder... Frustrated I decided to take it across the street to these guys and they replaced the right tensioner, found the real reason I was overheating and another sensor that was bad and called me an hour later saying I was done! I was afraid to ask how much and was shocked by how little they charged to work on a Corvette compared to other places I've been... These guys are the greatest!! Highly recommend their work to anyone!!
