Removal and Installation: Installation: Notes

Note the following, and install in the reverse order of removal.

• Check for deformation of the grommets (16 and 18 of Components).
• Insert the collar (15 of Components) vertically.
• Install the collar (5 of Components) with its lower surface horizontal.
• Temporarily tighten nuts and bolts when installing exhaust pipe assembly. Tighten them to the specified torque when connecting the vehicle rear to the vehicle front.
  CAUTION:

  • Always replace exhaust tube gaskets with new ones when reassembling.
  • Discard any heated oxygen sensor 2 which has been dropped onto a hard surface such as a concrete floor. Use a new one.
  • Before installing a new heated oxygen sensor 2, clean exhaust system threads using the heated oxygen sensor thread cleaner (commercial service tool: J-43897-18 or J-43897-12), and apply the antiseize lubricant (commercial service tool).
  • Never over torque heated oxygen sensor 2. Doing so may cause damage to heated oxygen sensor 2, resulting in the "MIL" coming on.
  • If heat insulator is badly deformed, repair or replace it. If deposits such as mud pile up on the heat insulator, remove 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 gases 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 mounting rubber, avoid twisting or unusual extension in up/down and right/left directions.
