Drive Belt: Testing and Inspection

Serpentine 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 generator or compressor pulleys.

^ If a whining noise is heard around tensioner or idler assemblies, check for possible bearing failure.

CAUTION: To avoid personal injury when rotating the serpentine belt tensioner, use a tight fitting 13 mm wrench that is at least 46 cm (18 inch) long.
