Removal And Installation: Installation
WARNING: This page is about a different car, the 2004 Infiniti M45. However, it is still accessible from the selected car via links, so may be relevant.
Install in the reverse order of removal.
CAUTION:
- Always replace exhaust gaskets with new ones when reassembling.
- 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; use a new one.
- When using heated oxygen sensor wrench [KV10114400 (J-38365)], tighten to the middle of specified torque because length of tool may induce slight indication increase. (Do not tighten to the maximum specified torque.)
- Before installing a new heated oxygen sensor, clean exhaust system threads using the heated oxygen sensor thread cleaner (commercial service tool: J-43897-18 or J-43897-12), and apply anti-seize lubricant (commercial service tool).
- Do not over torque heated oxygen sensor. Doing so may cause damage to the heated oxygen sensor, resulting in the MIL coming on.
- If the insulator is badly deformed, repair or replace it. If deposits such as mud pile up on the insulator, remove them.
- When installing insulator avoid large gaps or interference between insulator and each exhaust pipe.
- Remove deposits and left over gasket material from the sealing surface of each connection. Connect them securely to avoid gas leakage.
- Temporarily tighten mounting nuts on the exhaust manifold side and mounting bolts on the vehicle side. Check each part for unusual interference, and then tighten them to the specified torque.
- When installing each clamp, align the protrusion on insulator with the clamp hole.
- When installing each mounting rubber, avoid twisting or unusual extension in up/down and right/left directions.
- Install mounting rubbers on rear main muffler as shown in Fig 1.
