REMOVAL

CAUTION:

• 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.

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.

Inspection

INFOID:0000000001696389

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.
