Car overheated first.

Hello, to me, it sounds like perhaps you need another opinion. I wouldn't be surprised if it was a concern with the harmonic balancer - which is the crankshaft pulley, which could be worn out and requiring replacement. In this case, it's typically the deterioration of the dampener that causes it to be noisy and vibrate. However -- one wonders if the water pump and tensioner was indeed a problem in the first place, and one wonders if the belt could have been possibly routed wrong. Too hard to say at this point; but i would definitely suggest a second opinion. https://repairpal.com/repair-shops/chevrolet-repair-and-service-in-dumont-new-jersey
