Installation

NOTE: GM does not provide a timing mark diagram for belt installation without using the special tool(s) listed below.

TOOL REQUIRED
J 38613-A Camshaft Timing Clamps

1. Install the camshaft sprockets finger tight.

NOTE: Check to make, sure that the timing belt teeth are fully engaged with the camshaft sprockets.





2. Install the timing belt. Do this by routing the timing belt in a counterclockwise motion around the camshaft sprockets.





3. Install the timing belt tensioner actuator pulley. Tighten the tensioner actuator pulley bolt/screw to 50 Nm (37 ft. lbs.).
4. If any tensioner oil has been lost, refill the tensioner actuator with a SAE 5W30 Mobile 1 synthetic engine oil, or equivalent, through the end hole.
5. Fill the tensioner actuator to the bottom of the plug hole only when the tensioner actuator is fully retracted and the pin is installed.
6. Install the rubber end plug at the rear of the tensioner actuator. Push the rubber end plug until the plug is flush and snapped into place.
7. Check to make sure that the rubber end plug has sealed against the tensioner actuator case.

NOTE: Check to make sure that the tapered fulcrum of the tensioner actuator is properly seated in the bracket bushing. Rotate the tensioner pulley into the timing belt a maximum of 15 Nm (11 ft. lbs.) in order to allow the engagement of the actuator shaft into the pulley arm socket.





8. Install the timing belt tensioner actuator bushing into the side plate.
9. Inspect the tensioner bushings and the appropriate holes for dirt or any foreign material. Do not lubricate the tensioner bushings or the holes.
10. Install the tensioner actuator.
11. Install the tensioner actuator side plate. Tighten the tensioner actuator side plate bolts to 25 Nm (18 ft. lbs.).
12. Pull the lock pin. Discard the pin.
13. Retighten the tensioner pulley 15 Nm (11 ft. lbs.) counterclockwise in order to seat the pulley into the timing belt.
14. Install both of the right hand (rear bank) camshaft sprockets. Tighten the camshaft sprocket bolts to 130 Nm (96 ft. lbs.).
15. Remove the Camshaft Timing Clamps from the right-side (rear bank) side of the camshaft carrier.
16. Rotate the crankshaft 360 degrees clockwise while looking at the front of the engine. Align the crankshaft reference marks.
17. Check to make sure that both of the right-hang (rear bank) camshaft flats are down.





18. Install both of the left-hand (front bank) camshaft sprockets. Tighten the left hand camshaft sprockets to 130 Nm (96 ft. lbs.).
19. Remove the Camshaft Timing Clamps from the left-hand (front bank)
20. Rotate the crankshaft 720 degrees clockwise while looking at the front of the engine. Do this in order to seat the timing belt and verify the correct timing.
21. Check to ensure that both of the camshaft flat spots are up on one bank and down on the opposing bank.
22. Install the left side camshaft carrier cover.
23. Install the right side camshaft carrier cover.
24. Connect the breather hose to the rear camshaft cover.
25. Connect the crankshaft vent to the breather manifold.
26. Install the center timing belt cover.
27. Install the left upper timing belt cover.
28. Install the right upper timing belt cover.
29. Install the fuel line bracket and the fuel fine bracket bolt.
30. Install the wiring harness cover at the right strut tower.
31. Install the spark plug wires. See Powertrain Management.
32. Install the PCM electrical connectors. See Powertrain Management.
33. Connect the power steering lines to the power steering pump. See Steering and Suspension.
34. Install the accessory drive belt.
35. Install the accessory drive belt tensioner.
36. Install the coolant recovery reservoir. See Cooling System.
37. Install the upper intake manifold gasket.
38. Install the upper intake manifold.
39. Install the upper intake manifold support bracket nuts.
40. Install the power brake vacuum hose. See Brakes and Traction Control.
41. Install the wiring loom bracket for the rear spark plug wires.
42. Connect the vacuum lines to the upper intake manifold tee.
43. Install the canister purge solenoid electrical connector.
44. Install the MAP sensor electrical connector.
45. Install the EGR valve at the upper intake. See Powertrain Management.
46. Install the EGR valve electrical connector.
47. Connect the PCV valve and the vacuum line to the throttle body.
48. install the heater hose and the bracket to the lower intake manifold. See Heating and Air Conditioning.
49. Install the fuel line bracket and bolt.
50. Connect the fuel pipes to the fuel rail. See Powertrain Management.
51. Install the fuel injector sight shield. Refer to Engine Cover Replacement See Powertrain Management.
52. Connect the control cables at the throttle body. See Powertrain Management.
53. Install the air cleaner duct. See Powertrain Management.
54. Refill the coolant. See Cooling System.
55. Refill the power steering fluid. See Steering and Suspension.
56. Connect the negative battery cable.
