Nissan GT-R. Manual - part 93

EM-20

< REMOVAL AND INSTALLATION >

INTAKE MANIFOLD COLLECTOR

2.

Temporarily assemble intake manifold collector (1) and intake
manifold (2).

3.

Check an exact location that the intake manifold collector port
locates inside the intake manifold port and mark each part.
Refer to the arrow (A) shown in the figure to check the location.

4.

After another disassembly, install the parts, aligning with the
marks put before the temporary assembly.

CAUTION:

Tighten mounting bolts with care to avoid misalignment in
the intake manifold collector and intake manifold.

EVAP Tube (front)

• Tighten mounting bolts in numerical order as shown in the figure.

Electric Throttle Control Actuator

• Tighten bolts in numerical order as shown in the figure.

NOTE:
• The figure shows the electric throttle control actuator (bank 2)

viewed from the air duct side. 

• Viewed from the air duct side, the order of tightening mounting

bolts of electric throttle control actuator (bank 2) is the same as
that of the electric throttle control actuator (bank 1).

• Perform the “Throttle Valve Closed Position Learning” when har-

ness connector of electric throttle control actuator is discon-
nected. (This work is recommended to be performed by GT-R
certified NISSAN dealer.)

• Perform the “Idle Air Volume Learning” and “Throttle Valve

Closed Position Learning” when electric throttle control actuator is replaced. (This work is recommended to
be performed by GT-R certified NISSAN dealer.)

REMOVAL

1.

Remove intake manifold collector. Refer to 

EM-17, "Exploded View"

.

CAUTION:

Mark the parts with paint in advance of the reinstallation to prevent misalignment between the
intake manifold collector and intake manifold.

2.

Loosen pressure regulator and fuel hose assembly mounting bolt. Refer to 

EM-23, "Exploded View"

.

3.

Disconnect harness connector from fuel tube.

4.

Remove intake manifold.
• Loosen mounting bolts in reverse order as shown in the figure

with power tool.

CAUTION:

• Mark the parts with paint in advance of the reinstallation

to prevent misalignment between the intake manifold and
cylinder head.

• Cover engine openings to avoid entry of foreign materi-

als.

5.

Remove gaskets.

INSTALLATION

Note the following, and install in the reverse order of removal.

INTAKE MANIFOLD

• Tighten mounting bolts in numerical order as shown in the figure.

•  Refer to the figure to check the installation direction of the intake

manifold.

CAUTION:

• Install each part according to the marks put before removal.
• Tighten mounting bolts with care to avoid misalignment in the

intake manifold.

• After replacing an intake manifold, be sure to adjust the position as instructed below.
• Check an exact location that the intake manifold port locates inside

the cylinder head port and mark each part. Refer to the arrow (A)
shown in the figure to check the location.

CAUTION:

Tighten mounting bolts with care to avoid misalignment in the
intake manifold.
