6. Install the ignition coil electrical connection.
7. Install the left exhaust manifold to the cylinder head. Refer to Exhaust Manifold Replacement (Driver Side) .
8. Replace the two sealing rings on the coolant pipe.
9. Lubricate the two sealing rings with coolant.
10. Install the coolant pipe.
11. Install the upper radiator hose to the coolant pipe.
12. Install the upper radiator hose clamp.
13. Install the oil level indicator tube (4).
14. Install the coolant pipe/engine lift bracket bolt (2) to the cylinder head. Ensure the bolt passes through all attached components.

Tighten
Tighten the coolant pipe/engine lift bracket bolt to the cylinder head to 20 N·m (15 lb ft).

15. Install the exhaust camshaft. Refer to Camshaft Replacement.
16. Install the exhaust camshaft sensor electrical connection.
17. Install the rear timing belt cover. Refer to Timing Belt Rear Cover Replacement.
18. Install the water pump. Refer to Water Pump Replacement.
19. Install all four of the camshaft gears. Refer to Camshaft Drive Sprocket Replacement.
20. Install the timing belt tensioner bracket. Refer to Timing Belt Tensioner Pulley Replacement.
21. Install the timing belt. Refer to Timing Belt Replacement.
22. Install the front timing belt cover. Refer to Timing Belt Cover Replacement.
23. Install the LH valve cover. Refer to Camshaft Cover Replacement.
24. Install the coolant bridge. Refer to Engine Coolant Bridge Replacement.
25. Install the intake manifold spacer (2).
26. Install the intake manifold spacer bolts (1).

Tighten
Tighten the intake manifold spacer bolts in a spiral direction, starting from the inside and working outward, to 20 N·m (15 lb ft).

27. Install the intake manifold. Refer to Intake Manifold Replacement.
28. Install the intake air resonator. Refer to Intake Air Resonator Replacement in Engine Controls.
29. Install the intake plenum. Refer to Intake Plenum Replacement.
30. Reconnect the negative battery cable and reprogram the applicable accessories.
