Warning: Do not twist or bend the timing belt. Do not allow oil, coolant or fuel to come into contact with the timing belt.
If the timing belt teeth have chipped, the distributor, water pump, oil pump or camshaft may be seized.
Warning: If the timing belt breaks while the engine is running, the pistons may have struck the valves, causing the valves to be bent. Check the valve clearances. Bent valves will have significantly larger valve clearances than required.
If there is significant wear or delamination on the outer surface of the timing belt, check the condition of the idler pulley raceway.
If there is wear or damage on only one side of the belt, check the timing belt guide and timing belt pulley alignment.
If there are any defects on the toothed belt, it must be replaced. Periodic replacement of the toothed belt should be done after 100,000 km of the vehicle's mileage.
