The timing belt should be inspected at every oil change interval for evidence of any abnormal wear conditions. This is easily done by unclipping and removing the upper timing belt cover and performing a visual inspection. If any of the following conditions are noted, the belt and tensioner must be replaced immediately without
the vehicle any further:
- More than 1 or 2 mm gap between either edge of the belt and the base of the flange on the front and rear of the tensioner roller - indicating that the belt is mis-tracking and is wearing at the edges.
- Excessive wear on any of the edges of the belt, indicating mis-tracking.
- Evidence of cracks on the outer surface of the belt, indicating that the rubber material is deteriorating.
- Evidence of oil, fuel, or other fluids on the belt. These cause deterioration of the belt materials.
- Excessive wear on the teeth of the belt.
- If the belt has been on the vehicle for in excess of the time or mileage specified in the owner's manual, the belt and tensioner must be replaced with new components regardless of the result of any visual inspection.
