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. Refer to "Exploded View" Exploded View.
2.Remove air cleaner case and air duct (RH and LH). Refer to "Exploded View" 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.
- If stud bolts were removed, install them and tighten to the torque specified below.









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





- 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.





- 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.
Refer to "THROTTLE VALVE CLOSED POSITION LEARNING : Description" Description.
- Perform the "Idle Air Volume Learning" and "Throttle Valve Closed
Position Learning" when electric throttle control actuator is replaced. Refer to "IDLE AIR VOLUME LEARNING : Description" Description and "THROTTLE VALVE CLOSED POSITION LEARNING : Description" Description.
