For equivalent regional tools, refer to Special Tools .

Removal Procedure


1. Remove the intake manifold. Refer to Intake Manifold Replacement .

2. Remove the camshaft cover. Refer to Camshaft Cover Replacement - Right Side (LAU) Camshaft Cover Replacement - Right Side (LF1 or LFW) .

3. Remove the camshaft sensors. Refer to Camshaft Position Sensor Replacement - Bank 1 (Right Side) Exhaust and Camshaft Position Sensor Replacement - Bank 1 (Right Side) Intake .

4. Remove the intake camshaft position actuator solenoid. Refer to Camshaft Position Actuator Solenoid Valve Solenoid Replacement - Bank 1 (Right Side) Intake .

5. If equipped with LF1 engine remove the camshaft position actuator . Refer to Camshaft Position Actuator Replacement - Bank 1 (LF1 or LFW) .

6. If equipped with LAU engine remove the camshaft position actuator. Refer to Camshaft Position Actuator Replacement - Bank 1 (Right Side) Intake (LAU) .

7. Remove the crankshaft balancer. Refer to Crankshaft Balancer Replacement .

8. Rotate the crankshaft with the EN-46111 socket until the camshafts are in a neutral (low tension) position.

The camshaft flats will be parallel with the camshaft cover rail (1).


9. Refer to Torque Reaction Against Timing Drive Chain Caution .

Note
• Use an open-end wrench at the camshaft hex to prevent camshaft/engine rotation.

• DO NOT remove the camshaft position actuator bolt at this time.


Loosen the camshaft position actuator bolt.


10.
Note

Ensure that the tips of the EN-46313 tool are fully engaged into the timing chain.


Install the EN-46313 tool in order to retain the timing chain.

Firmly tighten the EN-46313 tool nuts .

11.
Note

Ensure that the camshaft timing chain and the camshaft position actuators are marked for proper assembly.


Mark the timing chain and the respective locations on camshaft position actuators (15-18).


12. Remove the camshaft position actuator bolt.

13. Remove the camshaft bearing caps and the camshaft. Refer to Camshaft Removal - Right Side .


Installation Procedure


1.
Note
• Ensure that the marks on the camshaft position actuators and the timing chain (15-18) are aligned.

• DO NOT tighten the camshaft position actuator bolt at this time.


Locate the camshafts to the cylinder head and assemble the camshaft actuators to the camshafts.
