Removal And Installation

INTAKE MANIFOLD

Removal and Installation


REMOVAL


WARNING:
To avoid the danger of being scalded, never drain the engine coolant when the engine is hot.
1.Remove engine cover. Exploded View.
2.Remove air duct (inlet) and air duct. Exploded View.
3.Disconnect harness connector and harness bracket (bank 2 rear side).
4.Remove engine cover bracket. Exploded View.
5.Disconnect air flow sensor harness connector.
6.Remove air flow sensor harness connector clip from intake manifold.
7.Remove vacuum tank, EVAP service port hose and EVAP canister purge control solenoid valve.
8.Disconnect PCV hoses and vacuum hose from intake manifold.
- Add matching marks as necessary for easier installation.
9.Drain engine coolant from radiator. Draining Engine Coolant.

CAUTION:
- Perform this step when the engine is cold.
- Never spill engine coolant on drive belts.
NOTE:
When removing only intake manifold, move electric throttle control actuator without disconnecting the water hoses.
10.Remove electric throttle control actuator.





- Loosen mounting bolts in reverse order as shown in the figure.
NOTE:
- The figure shows the electric throttle control actuator (bank 1)
viewed from the air duct side.
- Viewed from the air duct side, the order of loosening mounting bolts of electric throttle control actuator (bank 1) is the same as that of the electric throttle control actuator (bank 2).

CAUTION:
- Handle carefully to avoid any impact to electric throttle control actuator.
- Never disassemble.
11.Remove engine harness clip on rocker cover.
12.Remove water pipe mounting bolts. Refer Exploded View.
13.Remove water pipe mounting bolts (intake manifold back side). Refer Exploded View.
14.Remove high pressure fuel pump insulator. Exploded View.
15.Remove harness bracket (intake manifold back side).
16.Remove intake manifold.





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





17.Remove intake manifold gaskets.

CAUTION:
Cover engine openings to avoid entry of foreign materials.
18.Remove manifold absolute pressure (MAP) sensor, if necessary.

CAUTION:
Handle carefully to avoid any impact to manifold absolute pressure (MAP) sensor.
19.Remove acoustic absorbent.

INSTALLATION

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





Tighten in numerical order as shown in the figure.





Electric Throttle Control Actuator





- Tighten in numerical order as shown in the figure.
NOTE:
- The figure shows the electric throttle control actuator (bank 1)
viewed from the air duct side.
- Viewed from the air duct side, the order of tightening mounting bolts of electric throttle control actuator (bank 1) is the same as that of the electric throttle control actuator (bank 2).
- Perform the "Throttle Valve Closed Position Learning" when harness connector of electric throttle control actuator is disconnected.
Description.
- Perform the "Idle Air Volume Learning" and "Throttle Valve Closed
Position Learning" when electric throttle control actuator is replaced. Description and Description.
Water Hose
Insert hose by 27 to 32 mm (1.06 to 1.26 in) from connector end.
Vacuum Hose
