INTAKE MANIFOLD COLLECTOR


Removal and Installation


REMOVAL

WARNING:
Never drain engine coolant when the engine is hot to avoid the danger of being scalded.
1. Remove engine cover with power tool. Exploded View.
2. Remove air cleaner case and air duct (RH and LH). Exploded View.
3. Remove electric throttle control actuator as follows:
a. Drain engine coolant. When water hoses are disconnected, attach plug to prevent engine coolant leakage.

CAUTION:
- Perform this step when engine is cold.
- Never spill engine coolant on drive belt.
b. Disconnect water hoses from electric throttle control actuator. When engine coolant is not drained from radiator, attach plug to water hoses to prevent engine coolant leakage.
c. Disconnect harness connector.





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

NOTE:
- When removing only intake manifold collector, move electric throttle control actuator without disconnecting the water hose.
- 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 2) is the same as that of the electric throttle control actuator (bank 1).

CAUTION:
Handle carefully to avoid any shock to electric throttle control actuator.
4. Disconnect vacuum hose, PCV hose, and EVAP hose from intake manifold collector.
5. Remove EVAP canister purge volume control solenoid valve and EVAP tube assembly from intake manifold collector.





6. Loosen mounting bolts and nuts with power tool in the reverse order as shown in the figure to remove intake manifold collector.

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

INTAKE MANIFOLD COLLECTOR
- If stud bolts were removed, install them and tighten to the torque specified below.

Tightening Torque: 10.8 Nm (1.1 kg-m, 8 ft-lb)






- Tighten mounting bolts and nuts in numerical order as shown in the figure.

Arrow: Engine Front


WATER HOSE
- Insert hose by 27 to 32 mm (1.06 to 1.26 in) from connector end.
- Clamp hose at location of 3 to 7 mm (0.12 to 0.28 in) from hose end.

ELECTRIC THROTTLE CONTROL ACTUATOR (BANK 1 AND BANK 2)





- 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 2) is the same as that of the electric throttle control actuator (bank 1).
- Perform the "Throttle Valve Closed Position Learning" when harness connector of electric throttle control actuator is disconnected. Description Special Repair Requirement Description Special Repair Requirement Description Special Repair Requirement, "THROTTLE VALVE CLOSED POSITION
LEARNING : Description".
- Perform the "Idle Air Volume Learning" and "Throttle Valve Closed
Position Learning" when electric throttle control actuator is replaced. Description Special Repair Requirement, "IDLE AIR VOLUME
