For equivalent regional tools, refer to Special Tools (Special Tools).





Caution: Refer to Fastener Caution (Fastener Caution).

1. Install the intake manifold studs in the manifold face and tighten to 6 Nm (53 lb in).




2. Install the intake manifold (1). Start and hand tighten the intake manifold bolts and nuts.




3. Tighten the bolts and nuts in sequence to 10 Nm (89 lb in).




4. Install the intake manifold insulator (2).
5. Install the insulator bolt and tighten to 10 Nm (89 lb in).
6. Install the fuel rail harness connector bracket (1) to the intake manifold. Tighten the bracket bolt to 10 Nm (89 lb in).





Note: The camshaft must be in the base circle position before the high pressure fuel pump is installed.

7. Use the EN-48896 - alignment gauge (2) to ensure that the camshaft lobe is in the base circle position. At base circle position, the tool will be flush with the head (1).




8. Lubricate the high pressure fuel pump cylinder head bore with 5W30 engine oil.

Note: Ensure that the high pressure fuel pump roller lifter is oriented properly, the camshaft is at base circle, and the number 1 piston is at top dead center (TDC) on the exhaust stroke. The distance from the mounting flange surface to the camshaft at base circle should be 52 mm (2.05 in).

9. Lubricate the high pressure fuel pump roller lifter (1) with 5W30 engine oil and install into the cylinder head bore.
10. Install a NEW fuel pump housing O-ring (2) and gasket (3).

Note: Ensure the plastic bolt retainers are installed in the high pressure fuel pump mounting holes before installing.

11. Install the fuel pump assembly (4).
12. Start and hand-tighten the fuel pump assembly bolts evenly. Tighten the fuel pump bolts evenly to 15 Nm (11 lb ft).




13. Install and hand-tighten both ends of the NEW high pressure fuel line (1). Tighten the high pressure fuel line fitting nuts to 30 Nm (22 lb ft).




14. Install the fuel pump insulator (2).

Note: The low pressure fuel pipe used is model dependent.

15. Install the low pressure fuel pipe assembly (1).
16. Install the fuel pump cover (3) and nut. Tighten the nut to 10 Nm (89 lb in).




17. Install a new throttle body gasket.
18. Install the throttle body (1).
19. Install the throttle body bolts and tighten to 10 Nm (89 lb in).




20. Install the MAP sensor (3). Tighten the sensor bolt to 4 Nm (35 lb in).
21. Install the EVAP canister valve (2) and tighten to 25 Nm (18 lb ft).
22. Install the EVAP canister valve tube (1).




23. Install the O-ring and oil fill tube assembly (3).
24. Install the intake manifold cover (2) onto the camshaft cover ball studs.
25. Install the oil fill cap (1).
