INTAKE MANIFOLD
6. Loosen the bolts in the order as shown, and remove the intake
manifold.
INSPECTION AFTER REMOVAL
Surface Distortion
• Using straightedge and feeler gauge, inspect the surface distortion of the intake manifold. Refer to EM-146, "Removal and Installa-
tion".
INSTALLATION
Installation is in the reverse order of removal. Fo llow the procedure below for specific tightening sequences
and procedures.
CAUTION:
Do not reuse intake manifold gaskets.
• Install intake manifold nuts and bolts in two steps in the numerical order as shown.
NOTE:
After installation, it is necessary to re-calibrate the electric throttle control actuator as follows:
1. Perform the "Throttle Valve Closed Position Learning" when harness connector of the electric throttle con-
trol actuator is disconnected. Refer to EC-682, "Work Procedure"
.
2. Perform the "Idle Air Volume Learning" when the electric throttle control actuator is replaced. Refer to EC-
683, "Work Procedure".
3. Install the quick connector. Refer to EM-163, "Removal and Installation"
.
INSPECTION AFTER INSTALLATION
Make sure there are no fuel leaks at the 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.
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.
NOTE:
Use mirrors for checking on connections out of the direct line of sight.

b. Thinly apply new engine oil around fuel tube from tip end to spool end.
c. Align center to insert quick connector straightly into fuel tube. • Insert quick connector (1) to fuel tube until top spool (2) is
completely inside quick connector, and 2nd level spool (3)
exposes right below quick connector.
CAUTION:
• Do not reuse O-ring.
• Hold (A) position as shown 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 enga gement with a similar sound, be sure to perform the next step.
d. Pull quick connector by hand holding position. Check it is completely engaged (connected) so that it does
not come out from fuel tube.
e. Install quick connector cap (3) to quick connector.
• Install quick connector cap with arrow (A) on surface facing indirection of quick connector (fuel feed hose side).
CAUTION:
If quick connector cap cannot be installed smoothly, quick
connector may have not been installed correctly. Check
connection again.

• Before starting engine, check oil/fluid levels incl
uding engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-11, "FOR USA AND CANADA : Fluids and Lubricants"
.
• Use procedure below to check for fuel leakage.
• Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leak-
age at connection points.
• Start engine. With engine speed increased, check again for fuel leakage at connection points.
• Run engine to check for unusual noise and vibration. NOTE:
If hydraulic pressure inside timing chain tensioner dr ops after removal and installation, slack in the guide
may generate a pounding noise during and just after engine start. However, this is normal. Noise will stop
after hydraulic pressure rises.
• Warm up engine thoroughly to make sure there is no leak age of fuel, exhaust gas, or any oils/fluids including
engine oil and engine coolant.
• Bleed air from passages in lines and hoses, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to spec- ified level, if necessary.
