2010 Chevrolet Tahoe Repair Question
Mileage: No information provided.
Tensioner pulley lasted about 10min!!
Often it's the muck that's sprayed on that is causing the problem, belt grip is the worst of all. Remove the belt and clean or fit a new one, clean all the pulleys with solvent, check bearings of idler and tensioner pulleys, and re fit . Alignment should not be a problem as miss alignment will destroy a belt long before a pulley will fail. there are laser aligners out there to check these things, but that a bit much for the home mechanic to worry about.
