Removal and Installation


REMOVAL


WARNING:
To avoid the danger of being scalded, never drain the coolant when the engine is hot.
NOTE:
When removing components such as hoses, tubes/lines, etc., cap or plug openings to prevent fluid from spilling.
1.Disconnect battery negative terminal. Refer to "Removal and Installation (Battery)" Removal And Installation.
2.Release the fuel pressure. Refer to "Work Procedure" Testing and Inspection.
3.Partially drain engine coolant. Refer to "Changing Engine Coolant" Service and Repair.
4.Remove the air cleaner and air duct. Refer to "Removal and Installation" Removal And Installation.
5.Remove cowl top finisher. Refer to "Removal and Installation" Removal And Installation.
6.Remove strut tower bar. Refer to "Exploded View" Exploded View.
7.Disconnect the PCV hose from the intake manifold.
8.Disconnect the EVAP hose and EVAP canister purge volume control solenoid.
9.Disconnect the brake booster vacuum hose from the intake manifold.
10.Disconnect the fuel quick connector from the fuel tube assembly. Refer to "Removal and Installation" Removal And Installation.
11.Disconnect the water hoses from the electric throttle control actuator.
NOTE:
When removing only intake manifold, position electric throttle control actuator aside without disconnecting the water hose.





12.Loosen bolts in reverse order as shown, then remove electric throttle control actuator and gasket.

CAUTION:
Handle carefully to avoid any damage.
13.Disconnect the radiator hose (upper) from the water outlet. Refer to "Exploded View" Exploded View.
14.Disconnect electrical harness connectors from the tumble control valve, tumble control valve position sensor, and power valve motor.
15.Remove the fuel tube assembly. Refer to "Removal and Installation" Removal And Installation.





16.Remove the bolts and nuts in the reverse order shown using power tools and remove the intake manifold assembly with gasket.

CAUTION:
Cover engine openings to prevent entry of foreign materials.
NOTE:
Disregard No. 6 when loosening.

INSTALLATION

Installation is in the reverse order of removal. Follow the tightening sequences and specifications below and perform the following:
- Perform the "Throttle Valve Closed Position Learning" when harness connector of electric throttle control actuator is disconnected. Refer to "Work Procedure" Work Procedure.
- Perform the "Idle Air Volume Learning" and "Throttle Valve Closed Position Learning" when electric throttle control actuator is replaced. Refer to "Work Procedure" Work Procedure or "Work Procedure" Work Procedure.
Intake Manifold
1.Securely install gasket to the mounting groove.

CAUTION:
Do not reuse gasket.
2.If studs were removed, install them and tighten to specification.
Studs : 9.4 Nm (0.96 kg-m, 83 in-lb)





3.Tighten in numerical order as shown.

CAUTION:
After tightening the five bolts in the order shown, the 1, 6
position designates that the first bolt tightened is to be retightened to specification.

Bolts 1, 2, 3, 4, 5, 6 : 25.0 Nm (2.6 kg-m, 18 ft-lb)
Nuts 4, 5 : 25.0 Nm (2.6 kg-m, 18 ft-lb)
Bolt 7 : 45.0 Nm (4.6 kg-m, 33 ft-lb)

Electric Throttle Control Actuator
1.Install a new gasket on the electric throttle control actuator.

CAUTION:
Do not reuse gasket.





2.Tighten the bolts of electric throttle control actuator equally and diagonally in several steps in numerical order as shown.

INSPECTION AFTER INSTALLATION

Make sure there are no fuel leaks at connections as follows:
1.Apply fuel pressure to fuel lines by turning ignition switch ON (with engine stopped). Then check for fuel leaks at connections.
NOTE:
Use mirrors for checking on connections out of the direct line of sight.
2.Start the engine and rev it up and check for fuel leaks at connections.

WARNING:
Do not touch engine immediately after stopping as engine is extremely hot.
