i have a 1993 chevy lumina 2dr. last night i was driving home and i heard a thumping on my hood. so i stopped and i noticed a belt on the left side was starting to snap. i dont know anything bout cars so i dont know what belt that is. i continued driving and the whole belt snapped off. then my volts light came on. im guessing its the belt to the altenator from research online but i want to make sure. can anyone tell me what type of belt it is and how to go about fixing it>
