Removal procedure
1. Remove decorative engine covers. See «Decorative engine cover» in this section.
2. Remove the upper intake manifold assembly. See «Inlet manifold assy» in this section.
3. Remove cylinder head cover. See «cylinder head cover» in this section.
4. Remove the camshaft position sensors. See Part 1F3, "Engine Controls - HFV6 3.2L" (in the presence of).
5. Remove solenoid valves for variable valve timing (CMP). See Part 1F3, "Engine Controls - HFV6 3.2L" (in the presence of).
6. Remove the crankshaft balancer.
7. Using tool EN-46111, turn the crankshaft so that the camshafts are in the neutral position (weak tension). The flats of the camshaft will be parallel to the interface with the timing cover (1).
8. Install fixture EN-46105 (2) on the rear of the camshafts on the left side (1).
Important:
- To prevent rotation of the camshaft/engine, use an open wrench on the camshaft hex.
- DO NOT REMOVE the bolt securing the camshaft actuator to the camshaft yet.
9. Loosen the fixing bolt of the left intake valve timing actuator to the camshaft.
Important: The engine front cover in the following figures has been removed for clarity and is not required for this procedure.
10. Loosen tool EN-48313 to retract the uprights.
11. Insert the EN-48313 tool between the camshaft actuators, behind the timing chain so that the line engraved on the tool body (1) aligned with the top surface of the cylinder head (2). This is an approximate installation position.
12. Make sure the legs (2) on racks (1) EN-48313 fixtures face the front of the engine.
Important: DO NOT TIGHTEN the EN-48313 tool yet.
13. Slightly spread the racks (1) EN-48313 fixture by turning the T-handle clockwise.
Important: Make sure that the legs (2) EN-48313 fixtures were securely hooked into the notches of the chain links to prevent the chain from slipping during tightening.
14. Continue to extend the EN-48313 tool until the legs (2) will not enter the timing chain.
15. Finger tighten tool EN-48313.
Important: DO NOT rotate the EN-48313 tool body while tightening the T-handle.
16. Using an open wrench on the hex of the EN-48313 body, finger-tighten the T-handle.
17. Using an open wrench on the hex keys of the left intake and exhaust camshafts, rotate the camshafts towards each other to loosen the chain between the actuators.
18. The EN-48313 tool is now properly installed to hold the timing chain in position.
Important: Be sure to mark the timing chain and variable valve timing actuators to ensure their correct assembly.
19. Mark the timing chain and variable valve timing drives.
20. Unscrew the bolt securing the left intake valve timing actuator to the camshaft (1).
21. Remove the left intake camshaft control actuator (2).
Installation procedure
1. Make sure the correct valve timing actuator is installed. Check for the presence of markings on the body of the drive for regulating the valve timing "IN" (2). This marking indicates the intake camshaft control actuator.
2. Make sure to use the correct timing mark. follow label "L" on the outer ring of the camshaft control actuator and an annular mark (1). These marks are designed to align with the dedicated timing chain link on the left side of the engine.
3. Install the left intake camshaft control actuator (2).
Important:
- Make sure that the marks on the camshaft actuators and on the timing chain match.
- DO NOT TIGHTEN the bolt securing the right intake camshaft actuator to the camshaft yet (1).
4. Tighten the bolt securing the valve timing actuator to the camshaft (1).
- DO NOT TIGHTEN FULLY yet.
5. Remove tool EN-48313.
Important: To prevent the camshaft/engine from rotating, use an open wrench on the camshaft hex.
6. Tighten the screw securing the camshaft actuator to the camshaft.
Tighten
Tighten bolt to 58 Nm (43 lb-ft).
7. Remove tool EN-46105 (2) from the rear of the camshafts on the right side (1).
8. Install solenoid valves for variable valve timing (CMP). See Part 1F3, "Engine Controls - HFV6 3.2L" (in the presence of).
9. Install the camshaft position sensors. See Part 1F3, "Engine Controls - HFV6 3.2L" (in the presence of).
10. Install the crankshaft balancer.
11. Install the cylinder head cover. See «cylinder head cover» in this section.
12. Install intake manifold assembly. See «Inlet manifold assy» in this section.
13. Install decorative engine covers. See «Decorative engine cover» in this section.
