• 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.
