Removal and Installation: Removal

WARNING: This page is about a different car, the 2009 Nissan Maxima. However, it is still accessible from the selected car via links, so may be relevant.

WARNING:

Perform the work when the exhaust and cooling system have completely cooled down.
When removing the front and rear engine mounting through bolts and nuts, lift the engine up slightly for safety. For engine slingers, refer to "REMOVAL AND INSTALLATION ".

Remove engine and CVT assembly. Refer to "REMOVAL AND INSTALLATION ".
Remove the RH and LH three way catalyst supports.
Remove heated oxygen sensor 2 (bank 1), heated oxygen sensor 2 (bank 2), air fuel ratio (A/F) sensor 1 (bank 1) and air fuel ratio (A/F) sensor 1 (bank 2).
1. Remove harness connector of each sensor, and disconnect the harness from the bracket and middle clamp.
2. Remove both heated oxygen sensors and air fuel ratio (A/F) sensors using Tool.
  Tool numbers: KV10114400 (J-38365)
  
  : - (J-44626)
CAUTION:
- Be careful not to damage heated oxygen sensors or air fuel ratio (A/F) sensors.
- 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; replace with a new sensor.
Remove exhaust manifold and three way catalyst heat shields with power tool.
Remove the three way catalyst (manifold) (bank 1) and three way catalyst (manifold) (bank 2) by loosening the bolts first and then removing the nuts and through bolts.
