Re: Main Drive Belt Jumping Groove

You're new to the car, so you might not have any maintenance history, but it costs little to just replace the belt. That being said, I know that a Kevlar OEM-sized replacement is available - I'd get that if I could find it someplace. The kevlar backed belts are substantially stronger and more resistant to stretching than the standard belt.
My setup is far from standard, and I had a problem with the belt jumping, not due to alignment, just due to the loads being placed on the belt combined with my style of driving. When I finally switched to a kevlar belt, my problems disappeared. I keep a spare belt in the car just in case, but I haven't thrown a belt in 2 years.

Where are you finding the Kevlar belts ?
