Removal and Installation

EXHAUST SYSTEM


Removal and Installation


WARNING:
- Perform the procedure with the exhaust system fully cooled down because the system will be hot just after the engine is turned off.
- Be careful not to cut your hand on heat insulator edges.

CAUTION:
- Use genuine NISSAN exhaust system parts or equivalent, which are specially designed for heat resistance, corrosion resistance and shape.

REMOVAL
Remove exhaust system components using power tools.
- Remove heated oxygen sensor using Tool as needed.

Tool number : KV10114400 (J-38365)


CAUTION:
Be careful not to damage heated oxygen sensor.

INSTALLATION
Installation is in the reverse order of removal.

CAUTION:
- Always replace exhaust gaskets and seal bearings with new ones when installing.
- Before installing a new heated oxygen sensor, clean and apply anti-seize lubricant to exhaust system threads using suitable tool.





- Discard any heated oxygen sensor 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; install a new one.
- Do not over-tighten the heated oxygen sensor. Doing so may damage the heated oxygen sensor, 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 installing.
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 installing.
2. Install 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.
