It could be a too long belt, a failed tensioner or incorrectly adjusted tension, incorrect belt routing, failed pulley, out of the line accessory. Can you feel any movement on the pulleys when the belt is off? Zee

Are you using an after market belt? Or the cheapest? Opt for original equipment or a quality belt at your local parts store. Not all belts work . Let the buyer beware.
