Removal and Installation: Installation: Notes
Installation is in the reverse order of removal.
CAUTION:
- Always replace seal bearings and ring gaskets with new ones when reassembling.
- Temporarily tighten nuts and bolts. Check each part for unusual interference and mounting rubber interference, and then tighten them to the specified torque.
- 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 one.
- Before installing a new heated oxygen sensor 2, clean exhaust system threads using the heated oxygen sensor thread cleaner and apply anti-seize lubricant.
Oxygen sensor thread cleaner: - (J-43897-18)
Oxygen sensor thread cleaner: - (J-43897-12)
- Do not over-tighten heated oxygen sensor 2. Doing so may cause damage to the heated oxygen sensor 2, resulting in the MIL coming on.
- Prevent rust preventive from contacting sensor body.
- If heat insulator is badly deformed, repair or replace it. If deposits such as mud pile up on the heat insulator, clean and inspect them.
- When installing heat insulator avoid large gaps or interference between heat insulator and each exhaust pipe.
- Remove deposits from the sealing surface of each connection. Connect them securely to avoid exhaust leaks.
- Avoid twisting or deforming the mounting rubbers when installing them.
