age. Refer to
CAUTION:
Perform this step when the engine is cold.
4.
Remove front wiper arm and extension cowl top. Refer to
5.
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.
6.
Remove electric throttle control actuator as follows:
a.
Disconnect harness connector.
b.
Loosen mounting bolts in reverse order as shown in the figure.
CAUTION:
• Handle carefully to avoid any shock to electric throttle
control actuator.
• Never disassemble.
7.
Remove the following parts:
• Vacuum hose
• PCV hose
• High pressure piping from intake manifold collector: Refer to
.
• Electronic controlled engine mount control solenoid valve
8.
Disconnect EVAP hoses and harness connector from EVAP canister purge control solenoid valve.
9.
Remove EVAP canister purge control solenoid valve and bracket assembly.
10. Remove VIAS control solenoid valve mounting bolts and vacuum gallery mounting bolts, and then move
vacuum gallery.
• Add mating marks as necessary for easier installation.
11. Loosen mounting nuts and bolts in reverse order as shown in
the figure, and remove intake manifold collector and gasket.
CAUTION:
