Removal and installationNBS005RN
CAUTION:
Be sure to use genuine exhaust system parts or equivalents which are specially designed for heat
resistance, corrosion resistance, and shape.
Perform the operation with the exhaust system fully cooled down because the system will be hot
just after engine stops.
Be careful not to cut your hand on the heat insulator edge.
REMOVAL
Disconnect each joint and mounting using power tool.
Remove heated oxygen sensor 2 as follows:
–Using heated oxygen sensor wrench (SST), removal heated
oxygen sensor 2.
CAUTION:
Be careful not to damage heated oxygen sensor 2.
INSTALLATION
Note the following, and install in the reverse order of removal.
When installing, heated oxygen sensor 2 is identified by the color of the connector.
Install the collar (5 of Components) with its lower surface horizontal.
Temporarily tighten nuts and bolts when installing exhaust pipe assembly. Tighten them to the specified
torque when connecting the vehicle rear to the vehicle front.
CAUTION:
Always replace exhaust tube gaskets with new ones when reassembling.
Discard any heated oxygen sensor which has been dropped onto a hard surface such as a con-
crete floor; use a new one.
Before installing a new heated oxygen sensor, clean exhaust system threads using the heated
oxygen sensor thread cleaner [commercial service tool: J-43897-18 or J-43897-12], and apply the
anti-seize lubricant (commercial service tool).
Do not over torque heated oxygen sensor. Doing so may cause damage to heated oxygen sensor,
resulting in the “MIL” coming on.
If heat insulator is badly deformed, repair or replace it. If deposits such as mud pile up on the heat
insulator, remove them.
When installing heat insulator avoid large gaps or interference between heat insulator and each
exhaust pipe.
Remove deposits from the sealing surface of each connection. Connect them securely to avoid
gases leakage.
Check each part for unusual interference, and then tighten them to the specified torque.
When installing each mounting rubber, avoid twisting or unusual extension in up/down and right/
left directions.
INSPECTION AFTER INSTALLATION
Make sure clearance between tail tube and rear bumper is even.
With engine running, check exhaust tube joints for gas leakage and unusual noises.
Check to ensure that mounting brackets and mounting rubbers are installed properly and free from undue
stress. Improper installation could result in excessive noise and vibration.

WAR NING :
Read “General Precautions” when working on the fuel system. Refer to FL-3, "
General Precautions" .
1. Check fuel level on fuel gauge. If fuel gauge indicates more than
the level as shown in the figure (full or almost full), drain fuel
from fuel tank until fuel gauge indicates level as shown in the fig-
ure or below.
NOTE:
Because fuel will be spilled when removing main and sub fuel
level sensor units for the top of the fuel is above the main and
sub fuel level sensor units installation surface.
As a guide, fuel level becomes the position as shown in the
figure or below when approximately 20 (5-1/4 US gal, 4-3/8
Imp gal) of fuel are drained from fuel tank.
In a case that fuel pump does not operate, perform the follow-
ing procedure.
a. Insert hose of less than 25 mm (0.98 in) in diameter into fuel filler tube through fuel filler opening to draw
fuel from fuel filler tube.
b. Disconnect fuel filler hose from fuel filler tube. Refer to FL-10, "
FUEL TANK" .
c. Insert fuel tube into fuel tank through fuel filler hose to draw fuel from fuel tank.
2. Release the fuel pressure from the fuel lines. Refer to EC-98, "
FUEL PRESSURE RELEASE" (VQ35DE)
or EC-809, "
FUEL PRESSURE RELEASE" (VK45DE).

CAUTION:
Quick connector can be disconnected when the tabs
are completely depressed. Do not twist it more than
necessary.
Do not use any tools to disconnected quick connector.
Keep resin tube away from heat. Be especially careful
when welding near the resin tube.
Prevent acid liquid such as battery electrolyte, etc.
from getting on resin tube.
Do not bend or twist resin tube during installation and
disconnection.
Do not remove the remaining retainer on hard tube (or
the equivalent) except when resin tube or retainer is
replaced.
When resin tube or hard tube (or the equivalent) is
replaced, also replace retainer with new one.
To keep the connecting portion clean and to avoid
damage and foreign materials, cover them completely
with plastic bags or something similar.
8. Remove main fuel level sensor unit, fuel filter and fuel pump assembly, and sub fuel level sensor unit as
follows:
CAUTION:
Do not bend float arm during removal.
Avoid impacts such as falling when handling components.
a. Removal of main fuel level sensor unit, fuel filter and fuel pump assembly:
i. Remove retainer.
ii. Raise main fuel level sensor unit, fuel filter and fuel pump
assembly, and using snap ring pliers, remove fuel hose connec-
tor.
CAUTION:
Be careful not to damage fuel hose connector by expanding
them excessively.
b. Removal of sub fuel level sensor unit:
i. Remove retainer.
ii. Raise and release sub fuel level sensor unit to remove.
