REMOVAL

1.

Remove the air duct (inlet) and the air duct and resonator assembly. Refer to

EM-27, "Exploded View"

.

2.

Disconnect water hoses from electric throttle control actuator, attach blind plug to prevent engine coolant
leakage. (Northern Europe models)

CAUTION:

• Perform this step when the engine is cold.
• Never spill engine coolant on drive belts.

3.

Pull out oil level gauge.

CAUTION:

INTAKE MANIFOLD

5.

Disconnect the harness connector and EVAP hose from the EVAP canister purge volume control solenoid
valve.

6.

Disconnect vacuum hose for brake booster from intake manifold.

7.

Remove intake manifold support front (1) and rear (2).

8.

Remove intake manifold.
• Loosen bolts in the reverse of the order shown in the figure.

9.

Remove EVAP canister purge volume control solenoid valve from intake manifold, if necessary.

CAUTION:

Handle EVAP canister purge volume control solenoid valve carefully and avoid impacts.

10. Remove intake manifold support (center) from cylinder head, if necessary.

NOTE:
The intake manifold support (center) functions as the guide when the intake manifold is installed.

INSTALLATION

Note the following, and install in the reverse order of removal.

Intake Manifold

1.

Install the gasket to the intake manifold.
• Align the protrusion (A) of gasket to the groove of intake mani-

fold.

2.

Place the intake manifold into the installation position.

CAUTION:

Make sure that the oil level gauge guide is not disconnected from the fixing clip of water inlet due
to interference with intake manifold.
