Removal and Installation


  • 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 the insulator edges.


  • Use genuine NISSAN exhaust system parts or equivalent, which are specifically designed for heat resistance, corrosion resistance, and shape.

Remove exhaust system components using power tools.

  • Remove heated oxygen sensor using Tool as needed.

Tool number : KV10114400 (J-38365)

Installation is in the reverse order of removal.


  • Always replace exhaust gaskets with new ones when reassembling.
  • Before installing a new heated oxygen sensor, clean and lube the exhaust tube 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.
  • 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.
