INTAKE MANIFOLD
11. Loosen the bolts in reverse order shown using power tool.
12. Remove the intake manifold.CAUTION:
Cover engine openings to avoid entry of foreign materials.
• Clean all gasket mating surfaces, do not reuse gaskets.
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 sol enoid valve connector with it facing front of engine.
• Tighten the electronic throttle control actuator bolts of the electric throttle control actuator equally and diago-
nally in several steps.
• After installation perform procedure in "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 t he 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.
