2. Remove the generator.
3. Remove the engine coolant temperature (ECT) sensor.
4. NOTE: The LH and RH camshafts must be retimed when either camshaft is disturbed.
Turn the crankshaft clockwise to position the No. 1 cylinder at top dead center (TDC).
5. CAUTION: Do not rotate the engine counterclockwise. Rotating the engine counterclockwise will result in incorrect timing of the engine.
NOTE: The special tool must be installed on the damper and should contact the engine block, this positions the engine at TDC.
Install the special tool.
