Broken AC Belt
Engine Size: 5.3
Issue / Question:
My a/c belt broke. We replaced it with a belt from an autopart store with no problem. We test drove the vehicle and discovered a aweful noise which was the tensioner vibrating violently. We then replaced it 2 times; one time with an aftermarket one and it also vibrated violently. We then bought a gm tensioner and the problem continued. We have been told the compressor is going bad. It still blows cold air. Thank you for the help!
If you don’t have the problem with the A/C off it may very well be that the compressor is requiring excessive torque to turn causing the problem, this would mean the compressor is seizing internally and will need replacement.
