- If the timing belt is to be reused, make an arrow mark with something like chalk on the back of the belt indicating the direction of rotation so it may be reinstalled in the same direction. CAUTION: Never remove the timing belt with any piston at the top dead center (TDC). If a piston is at TDC, the exhaust valves of the cylinder are pushed by the exhaust cams, compressing the valve springs. If the belt is removed under this condition, the sprocket will be turned in the reverse direction by the force of the springs, incurring risk of injury.
- Set the timing mark of the exhaust camshaft sprocket to a point about one tooth before the TDC of the No. 1 cylinder piston on compression stroke.
- Loosen the lock nut of the tensioner pulley, then remove the timing belt.
