Drive Belt: Testing and Inspection

Serpentine Drive Belt Routing:

Inspect

^ If fraying of belt is noticed, check to make sure both the belt and tensioner assembly are properly aligned and that the belt edges are not in contact with the flanges of the tensioner pulley.
^ If, while adjusting belt tension, tensioner runs out of travel, the belt has stretched beyond adjustment and should be replaced.
^ If a whining noise is heard around tensioner or idler assemblies, check for possible bearing failure.
