Camshaft Position Actuator Replacement - Bank 1

Special Tools

1. EN49982-1 Timing Chain Retainer
2. EN49982-2 Timing Chain Retainer

For equivalent regional tools, refer to Special Tools .

1. Remove the camshaft cover. Refer to «Camshaft Cover Replacement - Right Side»(/buick/enclave/i-2007-2013/remont/mechanical/#engine-mechanical-36l-repair-instructions-on-vehicle__camshaft-cover-replacement-right-side) .
2. Remove the camshaft position actuator solenoid valve solenoid - intake. Refer to «Camshaft Position Actuator Solenoid Valve Solenoid Replacement - Bank 1 (Right Side) Intake»(/buick/enclave/i-2007-2013/remont/testing-diagnostics/#engine-controlsfuel-36l-repair-instructions) .
3. Remove the intake camshaft position sensor. Refer to «Camshaft Position Sensor Replacement - Bank 1 (Right Side) Intake»(/buick/enclave/i-2007-2013/remont/testing-diagnostics/#engine-controlsfuel-36l-repair-instructions) .
4. Remove the exhaust camshaft position sensor. Refer to «Camshaft Position Sensor Replacement - Bank 1 (Right Side) Exhaust»(/buick/enclave/i-2007-2013/remont/testing-diagnostics/#engine-controlsfuel-36l-repair-instructions) .
5. Remove the camshaft position actuator solenoid valve solenoid - exhaust. Refer to «Camshaft Position Actuator Solenoid Valve Solenoid Replacement - Bank 1 (Right Side) Exhaust»(/buick/enclave/i-2007-2013/remont/testing-diagnostics/#engine-controlsfuel-36l-repair-instructions) .
6. Rotate engine clockwise using crankshaft dampener retaining bolt until the flats at the rear ends of the camshafts are pointing up. This puts the camshafts on "base circle" and will reduce their tendency to rotate from valve spring pressure when the camshaft position actuators/drive chains are removed.
7. Loosen intake and/or exhaust camshaft position actuator retaining bolts, depending on which camshaft position actuator and/or camshaft you will be servicing. If servicing both camshaft position actuators and/or camshafts, loosen both bolts.
8. Mark the position of the chain to the camshaft position actuator - intake.
9. Mark the position of the chain to the camshaft position actuator - exhaust.
10. Remove camshaft front cap bolts (1).
11. Remove the camshaft front cap (1).
12. Loosen wingnut (4) to open the clamping area of EN49982-1 retainer.
13. Install EN49982-1 retainer intake side chain holder onto front cover by screwing in the thumbscrew (2) on the EN49982-1 retainer finger-tight.
14. Tighten wingnut (4) so EN49982-1 retainer closes over and firmly grasps timing chain.
15. EN49982-2 retainer (1) will be installed in the following steps such that it wedges between an internal rib (2) that is cast into the inside of the front cover (shown in dotted line above) and the timing chain and spring-loaded tensioner shoe (3), holding the chain in position. The wedge will be left in place during the cam position actuator and/or camshaft service.
16. Insert the EN49982-2 retainer between the two camshaft position actuators with the "teeth" on the EN49982-2 retainer facing toward the front cover.
17. Once the wedge portion of EN49982-2 retainer is below the camshaft position actuators, rotate the EN49982-2 retainer until the flat in the handle faces toward the intake camshaft position actuator. This orients the "teeth" toward the chain.
18. Drop the wedge down until it begins to engage the timing chain and the belt casting (2).
19. If possible shine a strong light down from above, between the camshaft position actuators, and see the wedge in overall position as shown in the above graphic.
20. Using a 20 mm wrench on the cast hexagonal portion of the exhaust camshaft, rotate the camshaft toward the intake camshaft while pushing down on the handle of the EN49982-2 retainer.
21. This rotation of the camshaft will compress the tensioner shoe (3) against the spring force of the tensioner, opening up a gap between the chain and the internal rib in the front cover. The wedge will then drop into this gap. You will feel a distinct click as the teeth engage the chain.
22. Release the force on the wrench, allowing the spring tension to close the tensioner shoe against the wedge portion of EN49982-2 retainer. You should be able to lightly tug on the EN49982-2 retainer and it should stay in position. Repeat Steps 20 and 21 if necessary to re-insert the EN49982-2 retainer until you are certain it is in position and will stay in position.
23. With EN49982-2 retainer in position and with the 20 mm wrench removed, there should now be some slack in the timing drive chain as indicated in the graphics shown.
24. Do not pry against the face of the camshaft position actuators or the position actuator retaining bolt.
25. Position a screwdriver or small pry bar between a camshaft cap and camshaft lobe. Carefully move/pry the camshafts as far as possible toward the rear/flywheel end of the engine.
26. The EN49982-1 retainer and EN49982-2 retainer should be in position as shown, they must be left in position during the servicing of the camshaft position actuator(s) and/or camshaft(s).
27. Remove and capture the plastic thrust washers (1) in the following steps. Ensure the plastic thrust washer does not fall into the front cover area.
28. To remove the intake camshaft position actuator, remove the loosened retaining bolt. To remove only the exhaust camshaft position actuator, skip the steps for removing the intake camshaft position actuator. However, the EN49982-1 retainer MUST be installed as discussed even if the intake side will not be serviced or the timing of the camshaft chains will be lost.
29. Slide the camshaft position actuator forward and off the end of the intake camshaft. The slot in the EN49982-1 retainer will allow the tool to move forward enough to disengage the camshaft position actuator from the front of the camshaft. Remove the plastic thrust washer when removing the camshaft position actuator from the end of the camshaft.
30. Tilt the camshaft position actuator forward and out/away from the engine.
31. Allow the chain to rest on the EN49982-1 retainer and EN49982-2 retainer in position during service.

1. Install plastic camshaft position actuator thrust washer (1) between cylinder head face and camshaft position actuator on assembly.
2. It may help to carefully pry the camshaft forward and to move the EN49982-1 retainer backward via the slot to reengage the position actuator to the camshaft. The dowel pin on the camshaft position actuator must be aligned with the slot in the camshaft nose for reassembly.
3. Install the intake camshaft position actuator first by inserting the actuator between the timing chain and front cover. Tilt the actuator in and engage the chain while aligning the marks you made on the chain and position actuator.
4. Ensure the camshaft position actuator fits snugly to the end of the camshaft.
5. Install the intake camshaft position actuator retaining bolt, and lightly tighten the bolt to hold the camshaft actuator in place. DO NOT torque at this time.
6. Install the exhaust camshaft position actuator retaining bolt, and lightly tighten the bolt to hold the camshaft actuator in place. DO NOT torque at this time.
7. Double-check that the marks on both the intake and exhaust camshaft position actuators to ensure that they are aligned with their respective paint marks on the chain.
8. Using a 20 mm wrench on the cast hexagonal portion of the exhaust camshaft, rotate the camshaft clockwise while pulling up on the handle of the EN49982-2 retainer.
9. Remove EN49982-2 retainer.
10. Release the pressure on the wrench. The timing chain should now be tight and should lose the slack the wedge was providing.
11. Torque one or both camshaft position actuator retaining bolts to 58 N.m (43 lb ft).
12. Unscrew the wingnut on EN49982-1 retainer to release timing chain, and then remove EN49982-1 retainer from the front cover by unscrewing the thumbscrew (2).
13. Install camshaft front cap and bolts (1).
14. Tighten the camshaft front cap outer bolts to 10 N.m (89 lb in).
15. Tighten the camshaft front cap inner bolts to 10 N.m (89 lb in).
16. Install the camshaft position actuator solenoid valve solenoid - exhaust. Refer to «Camshaft Position Actuator Solenoid Valve Solenoid Replacement - Bank 1 (Right Side) Exhaust»(/buick/enclave/i-2007-2013/remont/testing-diagnostics/#engine-controlsfuel-36l-repair-instructions) .
