6. Loosen, but DO NOT remove, the camshaft position exhaust actuator bolt (1)
7. Loosen, but DO NOT remove, the camshaft position intake actuator bolt (1).
8. Remove the EN-48953 - locking tool.
Note: Ensure the timing chain and the camshaft position actuators are marked for proper assembly.
9. Mark the intake and exhaust camshaft actuators and the respective locations on the timing chain (1). Mark additional the position from each camshaft actuator to the camshaft bearing cover (2).
10. Remove the timing chain tensioner. Refer to Timing Chain Tensioner Replacement Service and Repair.
11. Install the EN-48749 - retention tool(1) to the intake side of the timing chain.
12. Install the EN-48749 - retention tool(1) to the exhaust side of the timing chain.
13. Remove and DISCARD the camshaft position exhaust actuator bolt.
14. Rotate the exhaust camshaft clockwise with a open ended wrench slightly to take the tension off of the timing chain.
15. Remove the exhaust camshaft actuator from the camshaft while also removing the actuator from the timing chain.
16. Release tension from the exhaust camshaft and allow the exhaust camshaft to slide back slowly.
17. Remove and DISCARD the camshaft position intake actuator bolt (1)
18. Remove the intake camshaft actuator (2) from the camshaft while also removing the actuator from the timing chain.
Installation Procedure
1. Mark the new intake camshaft actuator at the same point as the old intake camshaft actuator.
Note: Ensure the timing chain and the camshaft position actuator is the marked points.
Ensure that the intake camshaft actuator fully fits in the intake camshaft.
2. Rotate the intake camshaft clockwise with a open ended wrench slightly to fit the intake camshaft actuator in the intake camshaft.
3. Install the intake camshaft actuator (2) to the camshaft while also installing the actuator at the timing chain.
4. Release tension slowly from the intake camshaft.
5. Install the NEW camshaft position intake actuator bolt (1) hand tighten.
6. Mark the new camshaft exhaust actuator at the same point as the old camshaft exhaust actuator.
Note: Ensure the timing chain and the camshaft position actuators are on their marked points.
Ensure that the exhaust camshaft actuator fully fits in the exhaust camshaft.
7. Rotate the exhaust camshaft clockwise with a open ended wrench slightly to fit the exhaust camshaft actuator in the exhaust camshaft.
8. Install the exhaust camshaft actuator (2) to the exhaust camshaft while also installing the actuator at the timing chain.
9. Release tension slowly from the exhaust camshaft.
10. Install the NEW camshaft position exhaust actuator bolt (1) hand tighten.
11. Remove both EN-48749 - retention tool from the timing chain.
12. Reset and install the timing chain tensioner. Refer to Timing Chain Tensioner Replacement Service and Repair.
13. Install the EN-48953 - locking tool(1) to the camshafts.
Caution: Refer to Fastener Caution Fastener Caution.
14. Install the EN-48953 - locking tool bolts and tighten to 10 Nm (89 lb in).
15. Tighten the exhaust camshaft actuator (2) a first pass to 30 Nm (22 lb ft).
Caution: Refer to Torque-to-Yield Fastener Caution Torque-to-Yield Fastener Caution.
16. Tighten the exhaust camshaft actuator (2) a final pass to an additional 100°, using the EN-45059 - meter.
17. Tighten the intake camshaft actuator (2) a first pass to 30 Nm (22 lb ft).
Caution: Refer to Torque-to-Yield Fastener Caution Torque-to-Yield Fastener Caution.
18. Tighten the intake camshaft actuator (2) a final pass to an additional 100°, using the EN-45059 - meter.
19. Remove the EN-48953 - locking tool.
20. Rotate the crankshaft clockwise at the crankshaft balancer bolt to 720 degrees and ensure that the marks are still fit. If the marks are not fit, refer to Camshaft Timing Chain, Sprocket, and Tensioner Replacement Camshaft Timing Chain, Sprocket, and Tensioner Replacement.
21. Install the front wheelhouse liner. Refer to Front Wheelhouse Liner Replacement Service and Repair.
22. Install the upper timing chain guide. Refer to Timing Chain Upper Guide Replacement Timing Chain Upper Guide Replacement.
23. Install the 4 spark plugs. Refer to Spark Plug Replacement Service and Repair.
