Has anyone ever had this problem? Idler arm for AC acsessary belt slipped down and ran the belt into the serpentine belt. Engine is stock except for intake. It seems like a tight squeeze to try to fix from the top. I Know what I have to do to fix it, but I am limited by doing it on the street. Any tips on an easy way to acsess this?(easier on jackstands or to take things out and go from the top?)
