Removal Procedure
1. Remove the camshaft cover.
2. Raise and support the vehicle. Refer to Vehicle Lifting.
3. Remove the engine front cover.
4. Lower the vehicle.
5. Important: To rotate the camshaft, use a 24 mm open-end wrench on the camshaft flats. Camshaft should be rotated in a clockwise direction
only, facing camshaft sprockets from the passenger side of the vehicle.
Locate the No. 1 piston to approximately 60 degrees before top dead center (diamond shaped hole on intake camshaft sprocket at 12 o'clock
position). Remove the spark plugs. This will ease the rotation effort.
6. Remove the timing chain tensioner.
