V-Ribbed Serpentine Belt With Chunks of Rib Missing
6. The condition of the V-ribbed drive belt should be compared against the illustration and appropriate action taken.
1
Small scattered deposits of rubber material. This is not a concern, therefore, installation of a new belt is not required.
2
Longer deposit areas building up to 50 percent of the rib height. This is not considered a concern but it can result in excessive noise. If noise
is apparent, install a new belt.
3
Heavy deposits building up along the grooves resulting in a possible noise and belt stability concern. If heavy deposits are apparent, install a
new belt.
7. There should be no chunks missing from the belt ribs. If the belt shows any evidence of this, install a new accessory drive belt.
8. If the concern is not visually evident, verify the symptom and GO to Symptom Chart. See: Symptom Related Diagnostic Procedures
