• Be careful not to cut your hand on the insulator edges.

CAUTION:

• Use genuine NISSAN exhaust system parts or equivalent, which are specifically designed for heat

resistance, corrosion resistance, and shape.

REMOVAL

Remove exhaust system components using power tools.

• Remove heated oxygen sensor using Tool as needed.

INSTALLATION

Installation is in the reverse order of removal.

CAUTION:

• Always replace exhaust gaskets with new ones when reassembling.

• Before installing a new heated oxygen sensor, clean and lube the exhaust tube threads using suit-

able 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.

• If any mounting insulator is badly deformed, repair or replace it. If deposits such as mud pile up on

the mounting insulator, clean and inspect them.

• When installing the insulator avoid large gaps or interference between the insulator and each

exhaust pipe.

• Remove deposits from the sealing surface of each connection. Connect them securely to avoid

exhaust gas leaks.

• Temporarily tighten the exhaust manifold side nuts and the vehicle side bolts. Check each part for

any interference, and then tighten the nuts and bolts to specification.

• When installing each mounting rubber, avoid twisting or excessive extension in up/down and right/

left directions.

• Tighten the bolts without causing interference with the flange.

Inspection After Installation

INFOID:0000000004205609

• With the engine running, check the exhaust tube joints for exhaust gas leaks and unusual noises.

• Check that the mounting brackets and mounting insulators are installed properly and free from excessive

stress. Improper installation could result in excessive noise, leaks, and vibration.
