Intake Manifold Collector: Removal and Installation
Intake Manifold Collector: Removal and InstallationREMOVAL
1) Remove the engine undercover using power tool.
2) Remove engine room cover using power tool.
3) Remove air cleaner case (upper) and air duct and resonator assembly.
4) Remove electronic throttle control actuator as follows:
a) Drain engine coolant, or when water hoses are disconnected, attach plug to prevent engine coolant leakage.
WARNING:
To avoid the danger of being scalded, never drain engine coolant when engine is hot.
CAUTION:
^ Perform when engine is cold.
^ Do not spill engine coolant on drive belt.
b) Disconnect water hoses from electronic 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 bolts in reverse order as shown.
CAUTION:
^ Handle carefully to avoid any shock to electronic throttle control actuator
^ Do not disassemble.
5) Remove the following parts:
^ Vacuum hose (to brake booster)
^ PCV hose
6) Loosen bolts in reverse order as shown to remove intake manifold collector support.
7) Disconnect EVAP hoses and harness connector from EVAP canister purge volume control solenoid valve.
8) Remove EVAP canister purge volume control solenoid valve.
9) Remove VIAS control solenoid valve and vacuum tank.
^ Add mating marks as necessary for easier installation.
10) Loosen nuts and bolts in reverse order as shown with power tool, and remove intake manifold collector.
CAUTION:
Cover engine openings to avoid entry of foreign materials.
INSTALLATION
Installation is in the reverse order of removal. Note the following:
Intake Manifold Collector
^ If stud bolts were removed from intake manifold, install them and tighten to the specified torque.
^ Tighten nuts and bolts in numerical order as shown.
Intake manifold collector bolts and nuts: 11.0 Nm (1.1 kg-m, 8 ft-lb)
Stud bolts: 6.9 Nm (7.0 kg-m, 61 in-lb)
Electronic Throttle Control Actuator.
^ Tighten bolts in numerical order as shown.
^ Perform the "Throttle Valve Closed Position Learning" when harness connector of electronic throttle control actuator is disconnected.
^ Perform the "Idle Air Volume Learning" and "Throttle Valve Closed Position Learning" when electronic throttle control actuator is replaced.
