Removal And Installation

INTAKE MANIFOLD

Removal and Installation


REMOVAL

1.Remove engine cover. Exploded View.
2.Pull out oil level gauge.

CAUTION:
Cover the oil level gauge guide openings to avoid entry of foreign materials.
3.Disconnect turbocharger boost sensor (with intake air temperature sensor 2) harness connector. Refer to
Exploded View.
4.Remove air inlet tube assembly. Exploded View.
5.Disconnect water hoses from electric throttle control actuator as follows:
- Attach plug to prevent engine coolant leakage when engine coolant is not drained. Draining Engine Coolant.

CAUTION:
Perform this step when the engine is cold.
NOTE:
This step is not required when removing only intake manifold.
6.Disconnect electric throttle control actuator harness connector.
7.Remove electric throttle control actuator.

CAUTION:
- Handle carefully to avoid any shock to electric throttle control actuator.
- Never disassemble electric throttle control actuator.
8.Remove EVAP vacuum tank.
9.Disconnect EVAP canister purge volume control solenoid valve harness connector, and them remove bracket with EVAP canister purge volume control solenoid valve.
10.Remove vacuum gallery.
11.Disconnect PCV hose (intake manifold side).





12.Remove intake manifold (1) with the following procedure.
- Loosen and remove intake manifold mounting bolt (A).





- Loosen mounting bolts in reverse order as shown in the figure.

White arrow indicates : Engine front

NOTE:
Disregard the numerical order No.6 in removal.

CAUTION:
Cover engine openings to avoid entry of foreign materials.

INSTALLATION

Note the following, and install in the reverse order of removal.
Intake Manifold
1.Check if gasket is not dropped from the installation groove of intake manifold.
2.Install intake manifold with the following procedure:





a.Tighten in numerical order as shown in the figure.

White arrow indicates : Engine front

NOTE:
- Tighten bolt the No.1 in two steps.
- The numerical order No.6 shows the second step.
3.Install in the reverse order of removal after this step.

CAUTION:





Since check valve is built-in inside vacuum hose (1), install the vacuum hose fitting the arrow (A) to intake manifold side (2).
Electric Throttle Control Actuator
- Tighten bolts of electric throttle control actuator equally and diagonally in several steps.
- Perform "Throttle Valve Closed Position Learning" after repair when removing harness connector of the electric throttle control actuator. Work Procedure.
- Perform "Throttle Valve Closed Position Learning" and "Idle Air Volume Learning" after repair when replacing electric throttle control actuator. Work Procedure and Work Procedure.
