TSB : Drive Belt Routing: Inspection: Notes

Details

Inspect belt for fraying. If fraying has occurred, ensure belt and tensioner are aligned properly. If tensioner has reached its limit of travel, belt is excessively stretched and replacement of belt is required. If excessive noise is noticed from tensioner or idler, check for possible bearing failure. Small cracks in the back of the belt are acceptable. DO NOT apply Belt Dressing or any other additive to serpentine belt.
