What causes glazing at the edges of a serpentine belt?

Glazing at the edges of a serpentine belt, or on its ridges or in the grooves, results from the belt slipping. It indicates that friction between the belt and the accessory drive pulley (s) created by slipping has overheated the belt. Fraying at the edge of a belt indicates pulley misalignment.

Place the straightedge across two pulley faces. The straightedge should lie flat across them. If it doesn’t, one of the pulleys is misaligned.
