My daughter just purchased an 06 Aveo LS Automatic with 108,000 miles. The other night when she got home, the serpentine belt was dragging under the car. I was able to find a great youtube video and had the belt replaced in short time. Now there is a chatter coming from that area of the engine. Thinking it may be scraps from the old belt stuck in the pulleys, I removed some of what I could find. Replaced the belt and the noise is still there. THe drive belt was recently checked and must have been replaced before she bought the car. As a realistic person, I look for the cause - what caused the belt to break in the first place. Maybe something seized up? Would there be damage to the crankshaft area? Water pump? Any direction of help on this elusive car would help immensely. Thanks in advance.
