EM-182
[VK45DE]
INTAKE MANIFOLD
Revision: 2006 December 2006 FX35/FX45
INSPECTION AFTER REMOVAL
Surface Distortion

Check the surface distortion of both the intake manifold (upper
and lower) mating surfaces with straightedge and feeler gauge.

If it exceeds the limit, replace intake manifolds (lower and/or
upper).
INSTALLATION
Note the following, and install in the reverse order of removal.
Intake Manifold (Lower)
Tighten in numerical order as shown in the figure.

There are two types of mounting bolts. Refer to the following for
locating bolts.
Intake Manifold (Upper)
Tighten in numerical order as shown in the figure.
Electric Throttle Control Actuator

Install gasket with its directional protrusion set up/downward.

Tighten mounting bolts of electric throttle control actuator equally and diagonally in several steps.

After installation perform procedure in EM-182, "INSPECTION AFTER INSTALLATION" .
Water Hose
Insert hose by 27 to 32 mm (1.06 to 1.26 in) from connector end.
Vacuum Hose
Refer to EC-768, "Vacuum Hose Drawing" .
INSPECTION AFTER INSTALLATION

Perform the “Throttle Valve Closed Position Learning” when harness connector of electric throttle control
actuator is disconnected. Refer to EC-744, "
Throttle Valve Closed Position Learning" .

Perform the “Idle Air Volume Learning” and “Throttle Valve Closed Position Learning” when electric throt-
tle control actuator is replaced. Refer to EC-744, "
Idle Air Volume Learning" .
Limit : 0.1 mm (0.004 in)

16. Loosen mounting nuts in reverse order as shown in the figure to remove exhaust manifold.
NOTE:
Disregard the numerical order No. 9 to 12 in removal.
17. Remove exhaust manifold gaskets. CAUTION:
Cover engine openings to avoid entry of foreign materials.
INSPECTION AFTER REMOVAL
Surface Distortion

Check the surface distortion of the each exhaust manifold flange
mating surface with straightedge and feeler gauge.

If it exceeds the limit, replace exhaust manifold.
INSTALLATION
Note the following, and install in the reverse order of removal.
Exhaust Manifold Gasket
Install exhaust manifold gasket with its directional protrusion set upward.
Refer to the figure of components on former page. Refer to EM-183, "
