2. Remove the reservoir tank. Refer to CO-16, " Component " .
3. Remove the oil level gauge. CAUTION:
Cover the oil level gauge gu ide openings to avoid entry of foreign materials.
4. Remove electric throttle control actuator and position aside. CAUTION:
• Handle electric throttle control act uator carefully and avoid impacts.
• Never disassemble or adjust elect ric throttle control actuator.
5. Disconnect the harness connector and EVAP hose from the EVAP canister purge volume control solenoid
valve.
6. Disconnect vacuum hose for brake booster from intake manifold.

7. Remove intake manifold support front (1) and bolt from rear (2).
• Bracket (2) is not removed. Remove bolt from intake manifold.
8. Remove intake manifold. • Loosen bolts in the reverse of the order shown.
9. Remove EVAP canister purge volume control solenoid valve from intake manifold, if necessary. CAUTION:
Handle EVAP canister purge volume control solenoid valve carefully and avoid impacts.
10. Remove intake manifold support (center) from cylinder head, if necessary. NOTE:
The intake manifold support (center) functions as the guide when the intake manifold is installed.
INSTALLATION Installation is in the reverse order of removal.
Intake Manifold 1. Install the gasket to the intake manifold. • Align the protrusion (A) of gasket to the groove of intake mani-fold.
2. Place the intake manifold into the installation position. CAUTION:
Make sure that the oil level gauge guide is not disconnected from the fixing clip of water inlet due
to interference with intake manifold.

1. Tighten exhaust manifold nuts to specification in two stages in
the numerical order shown.
2. Use Tool (A) to install the air fuel ratio sensor 1. CAUTION:
• Handle it carefully and avoid impacts.
• Before installing a new air fu el ratio sensor 1, clean the
exhaust tube threads using suitable tool and approved
anti-seize lubricant.
• Do not over-tighten the air fu el ratio sensor 1. Doing so
may damage the air fuel rati o sensor 1, resulting in the
MIL coming on. : Engine front ALBIA0625ZZ
