INSTALLATION
Installation is in the reverse order of removal.
Tighten the intake manifold bolts in numerical order as shown.
Install the EVAP canister purge control solenoid valve connector with it facing front of engine.
Tighten the electronic throttle control actuator bolts of the electric throttle control actuator equally and
diagonally in several steps.
After installation perform procedure in EM-20, "INSPECTION AFTER INSTALLATION" .
Install the water hose so that its overlap width for connection is between 27 mm (1.06 in) and 32 mm (1.26
in) (target: 27 mm 1.06 in).
Connecting Quick Connector of Fuel Tube
Install quick connector as follows (the steps are the same for quick connectors on both engine side and vehi-
cle side except for the quick connector cap).
1. Make sure no foreign substances are deposited in and around tube and quick connector, and they are not
damaged.
2. Thinly apply new engine oil around the fuel tube from tip end to the spool end.
3. Align center to insert quick connector straight into fuel tube.
Insert until the paint mark for engagement identification
(white) goes completely inside quick connector so that you
cannot see it from the straight side of the connected part. Use
a mirror to check this where it is not possible to view directly
from the straight side, such as quick connector on vehicle
side.
Insert fuel tube into quick connector until top spool is com-
pletely inside quick connector, and 2nd level spool exposes
right below quick connector on engine side.
CAUTION:
Hold "A" position in illustration when inserting fuel
tube into quick connector.
Carefully align center to avoid inclined insertion to pre-
vent damage to O-ring inside quick connector.
Insert until you hear a "click" sound and actually feel
the engagement.
To avoid misidentification of engagement with a similar
sound, be sure to perform the next step.
4. Pull quick connector by hand holding "A" position. Make sure it is completely engaged (connected) so that it does not come out from fuel tube.
NOTE:
Recommended pulling force is 50 N (5.1 kg, 11.2 lb).
