Intake Manifold Collector

INTAKE MANIFOLD COLLECTOR








Removal and Installation

REMOVAL

WARNING:
^ To avoid the danger of being scalded, never drain the coolant when the engine is hot.
^ The gasket for intake manifold collector (upper) is secured together with intake manifold collector (lower) bolt. Thus, when replacing only the upper gasket the lower gasket must also be replaced.

1. Remove the cowl top. Refer to "Removal and Installation".
2. Remove the windshield wiper assembly. Refer to "Removal and Installation of Wiper Motor and Linkage".





3. Remove the engine cover using power tool.
4. Remove air cleaner case lid and mass air flow sensor, and air intake tube as an assembly. Refer to "Removal and Installation".
5. Partially drain the coolant when the engine is cool. Refer to "DRAINING ENGINE COOLANT".
6. Disconnect the following:
^ Power brake booster vacuum hose
^ Coolant hoses from the intake manifold collector
^ Swirl control vacuum lines to power valve and intake manifold collector upper
^ Fuel injector electrical connectors
^ PCV hose
^ Electric throttle control actuator electrical connector
^ EVAP canister purge hose
^ EGR temperature sensor electrical connector

CAUTION:
^ Cover any engine openings to avoid the entry of any foreign material.

7. Remove the EGR tube (to lower intake manifold collector) nuts.
8. Disconnect the power steering hose bracket from the rear of the intake manifold collector.
9. Remove the EVAP canister purge volume solenoid valve bracket bolt. Position the valve aside.
10. Remove the VIAS control solenoid valve bracket bolt. Position the valve aside.
11. Remove the vacuum tank.
12. Remove the intake manifold collector support bracket from the back of the intake manifold collector using power tool.





13. Loosen the intake manifold collector bolts in the order shown using power tool, and remove the intake manifold collector and gasket.





14. If necessary, remove the electric throttle control actuator bolts in the order shown and remove the electric throttle control actuator.

CAUTION:
^ Handle carefully to avoid any shock to the electric throttle control actuator.
^ Do not disassemble.





15. If necessary, remove the intake manifold collector (upper) bolts in the order shown, using power tool and remove the intake manifold collector.

CAUTION: Handle carefully to avoid any shock to the electric throttle control actuator, if installed.





16. If necessary, remove power valve bolts in the order shown and remove the power valve.
17. If necessary remove the following components:
^ Vacuum tank
^ VIAS control solenoid valve
^ EVAP canister purge volume control solenoid valve

INSTALLATION
Installation is in the reverse order of removal, paying attention to the following.

NOTE: After installation, it is necessary to re-calibrate the electric throttle control actuator as follows:

1. Perform the "Throttle Valve Closed Position Learning" when harness connector of the electric throttle control actuator is disconnected. Refer to "Throttle Valve Closed Position Learning".
2. Perform the "Idle Air Volume Learning" when the electric throttle control actuator is replaced. Refer to "Idle Air Volume Learning".





^ If necessary, install power valve bolts in the order shown.

Power valve bolts : 17.6 - 21.6 Nm (1.8 - 2.2 kg-m, 13 -15 ft. lbs.)





^ If necessary, tighten the intake manifold collector pipe bolts in the order shown.

Intake manifold collector pipe bolts : 17.6 - 21.6 Nm (1.8 - 2.2 kg-m, 13 - 15 ft. lbs.)





^ If necessary, install the electric throttle control actuator bolts in the order shown. Install gasket with three protrusions facing down.

Electric throttle control actuator bolts : 7.2 - 9.6 Nm (0.74 - 0.97 kg-m, 64 - 84 inch lbs.)





^ Install the intake manifold collector bolts in the order shown.
Intake manifold collector bolts : 17.6 - 21.6 Nm (1.8 - 2.2 kg-m, 13 -15 ft. lbs.)
