.
- Loosen the plenum duct clamp at the front of the intake manifold.
- Remove 10 bolts attaching the intake manifold to the cylinder heads.
- Remove the intake manifold by using an upward lifting motion at the rear of the manifold assembly.

Installation Procedure
- Lightly lubricate the inside edge of the rubber plenum duct.
- Clean any debris from the cylinder head and intake manifold.
- Install the new gaskets to the intake manifold.
Important: Ensure the PCV valve hose is firmly connected to the fitting at the rear of the intake manifold, prior to installation.
- Place the intake manifold in position by completing the following:
4.1. | Position the front of the intake manifold (1) into the plenum duct (2). |
4.2. | Position the rear of the intake manifold (1) downward on to the cylinders heads. |
- Loosely install the 10 bolts attaching the intake manifold (1) to the cylinder heads.
Notice: Refer to Fastener Notice in the Preface section.
- Tighten the intake manifold bolts in sequence (1-10).
Tighten
Tighten the intake manifold bolts to 10 N·m (89 lb in).
- Ensure that the plenum duct is fully attached to the front of the intake manifold.
Tighten
Tighten the plenum duct clamp (1) to 2.25 N·m (20 lb in).
- Install the fuel rail assembly. Refer to
Fuel Injection Fuel Rail Assembly Replacement
.
- To clean, turn the ignition switch to the ON position for 2 seconds, then turn to the OFF position for 10 seconds. Again turn to the ON position and check for fuel leaks.
- Install the fuel injector sight shield. Refer to
