My old drive belt was sqeeking so i replaced it. The new belt does not squeak but it keeps slipping off. But when I put the old one back on it does not slide off. Why is this? I replaced tensioner and idler pulleys but new belt still slips off. The old one still stays on. Car is 97 jeep grand cherokee. 5.2L
My car has an automatic transmission.
