• EN-48313 Timing Chain Retention Tool


For equivalent regional tools, refer to Special Tools .

Removal Procedure


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

2. Remove the fuel pump from the cylinder head. Refer to Fuel Pump Replacement .

3. Remove the left bank camshaft cover. Refer to Camshaft Cover Replacement - Left Side (LAU) ; Camshaft Cover Replacement - Left Side (LF1 or LFW) .

4. Remove the camshaft sensors. Refer to Camshaft Position Sensor Replacement - Bank 2 (Left Side) Exhaust and Camshaft Position Sensor Replacement - Bank 2 (Left Side) Intake .

5. Remove the camshaft position actuator solenoid. Refer to Camshaft Position Actuator Solenoid Valve Solenoid Replacement - Bank 2 (Left Side) Intake .

6. Remove the camshaft position actuator. Refer to Camshaft Position Actuator Replacement - Bank 2 (LF1 or LFW) .

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

8. Rotate the crankshaft with the socket EN-46111 until the camshaft is in neutral position (low voltage). The camshaft flats must be parallel with camshaft cover's 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-48313 tool in order to retain the timing chain.

Firmly tighten the EN-48313 tool nuts .

11.
Note

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