One day the belt comes off and I replace it with a new one. Couple of days later it comes off again, so I take it to a mechanic. They check it out and replace the belt. About 30 miles later it comes off again. I take it back they check the pulleys and they replace the tensioner. Runs well for a few weeks and the belt comes off. I take it to a different mechanic and check it out and change the alternator. It’s been three months since then and the belt came off again. From what I can tell is that the belt eventually works it’s way off until it starts coming apart and comes off. I could use any help or advice. Thank you
Pop the hood while running and watch all the pullys, next remove the belt and spin pullies by hand and inspect for wobble/any high spot. Next id inspect the belts tension, either try to move the tensioner belt off or pull on the belt while its on(not running)
