So I was driving my 93 civic when the alternator belt flew off. I assumed that I could just replace the belt. When I went to replace It I noticed the belt was not goin on strait but I tightened it Down and turned the car on the belt Cale right off again and the crank pully was crooked... WTF? I have another pully but if I change it out will it fix the problem this has never happened to me before.
