Serpentine belt

Hi - Dave here, contributing to RepairPal and providing expert advice since 2010. It sounds like one of the pulleys that is driving the belt is frozen, causing the belt to come off. It is important to find out which one is frozen so that troubleshooting can determine what is needed to resolve the problem. https://repairpal.com/auto-repair-near-me Click the link to find some shops near you who can help out!
