• Be sure to use genuine NISSAN 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 the engine stops.
• Be careful not to cut your hand on heat insulator edge.
1. Disconnect harness connector of heated oxygen sensor 2.
• Using Tool, remove heated oxygen sensor 2.
CAUTION:
Be careful not to damage heated oxygen sensor 2.
a.2. Disconnect each joint and mounting rubber.
INSTALLATION
Installation is in the reverse order of removal.
CAUTION:
• Always replace exhaust gaskets and seal bearings with new ones when installing.
• Discard any heated oxygen sensor 2 which has been dropped from a height of more than 0.5 m (19.7
in) onto a hard surface such as a concrete floor; use a new one.
• Before installing a new heated oxygen sensor 2, clean exhaust system threads using the heated oxy-
gen sensor thread cleaner and apply anti-seize lubricant (commercial service tool).
• Do not over tighten heated oxygen sensor 2. Doing so may cause damage to the heated oxygen sen-
sor 2, resulting in the “MIL” coming on.
• Remove deposits from the sealing surface of each connection. Connect them securely to avoid
exhaust leakage.
• Temporarily tighten nuts on the exhaust manifold side and bolts on the vehicle side. 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.
Exhaust Manifold to Exhaust Front Tube
1. Securely insert seal bearing (2) into exhaust manifold (1) side in
the direction shown.
• Exhaust front tube (5)
CAUTION:
Be careful not to damage seal bearing surface when install-
ing.
2. Install spring (3), tighten nut (4).
• Be careful that the stud bolt nut does not interfere with the
flanged area ( ).
• Make sure the spring (3) sits properly on the flange surface by
aligning it to the locator dimples.
Exhaust Front Tube to Center Muffler
1. Securely insert seal bearing (2) into exhaust front tube (1) side
in the direction shown.
• Center muffler (5)
CAUTION:
Be careful not to damage seal bearing surface when install-
ing.
2. With spring (3), tighten bolt (4).
• Be careful that the stud bolt does not interfere with the flanged
area ( ).
• Make sure the spring (3) sits properly on the flange surface by
aligning it to the locator dimples.
INSPECTION AFTER INSTALLATION
• With the engine running, check exhaust tube joints for exhaust leakage and unusual noise.
• Check to ensure that brackets and mounting rubbers are installed properly and free from undue stress.
Improper installation could result in excessive noise and vibration.Tool number : KV10114400 (J-38365)

FUEL TANK
Disconnect electrical connector (A) and fuel feed hose quick connec-
tor (B).
• Fuel feed hose (1)
•⇐ : Vehicle front
• Disconnect the quick connector using the following procedure.
- Hold the sides of the connector, push in tabs and pull out the tube.
- If quick connector and tube on fuel pump assembly are stuck, push
and pull several times until they move. Disconnect them by pulling.
CAUTION:
• The tube can be removed when the tabs are completely
depressed. Do not twist it more than necessary.
• Do not use any tools to remove the quick connector.
• Keep resin tube away from heat. Be especially careful when
welding near the resin tube.
• Prevent acid liquid such as battery electrolyte, from getting
on resin tube.
• Do not bend or twist resin tube during installation and
removal.
• To keep the connecting portion clean, free of foreign materi-
als and to avoid damage, cover them completely with plastic
bags or something similar.
• Do not insert plug to prevent damage to O-ring in quick con-
nector.
6. Remove center exhaust tube. Refer to EX-4
.
7. Remove exhaust heat shields.
8. Disconnect parking brake cables (1) from the lower surface of
fuel tank and axle and position the parking brake cables (1) out
of the way.
