Why does my serpentine belt keep slipping on pulleys?
Serpentine belts stretch with age and use, but the tensioner is spring-loaded to keep the belt tight on the pulleys. If a belt starts slipping, the tensioner should always be checked to see if it is functioning properly.
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.
What do I do if the fan pulley does not turn?

How can I tell if my serpentine belt is out of alignment?
Belt tension on the pulley pulls the shaft off center, which puts that pulley out of alignment with the other pulleys. Pulley alignment can be checked with a straightedge. Place the straightedge across two pulley faces. The straightedge should lie flat across them. If it doesn’t, one of the pulleys is misaligned.
Is the serpentine belt a serious car problem?

How can I test my idler pulley for wobble?
There should be no wobble and no lateral play. Idler pulleys are checked the same way. Next, test the tensioner spring and arm operation. Using the breaker bar or serpentine belt tool, move the tensioner arm against the spring as far as it will move, to its stop.
