Check Ribbed Belt - 1- For:
- Sub-surface cracks (cracks, core ruptures, cross sectional breaks)
- Separation (cover layer, belt cords)
- Breaks at lower layer
- Fraying of cords
- Wear at flanks (material wear, frayed flanks, hardening or glazing of flanks, surface cracks)
CAUTION:
- The ribbed belt must be replaced if any damage is found.
- Ribbed belts on diesel engines, which have come into contact with oils, brake fluid, fuel or AdBlue, must always be replaced.
- Ribbed belts on gasoline engines, which have come into contact with oils, brake fluid, fuel or coolant, must always be replaced.
- This will prevent any belt malfunctions.
- Replacing the belt is a repair procedure.
