REMOVAL

• Disconnect each joint and mounting using power tool.
• Remove heated oxygen sensor 2 as follows:
- Using heated oxygen sensor wrench [SST: KV10114400 (J-

38365)] (C), removal heated oxygen sensor 2.

CAUTION:

Be careful not to damage heated oxygen sensor 2.

INSTALLATION

Note the following, and install in the reverse order of removal.
• Check for deformation of the grommets (20 and 22 of Components).
• Insert the collar (19 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 which has been dropped onto a hard surface such as a concrete

floor. Use a new one.

• Before installing a new heated oxygen sensor, clean exhaust system threads using the heated oxy-

gen sensor thread cleaner [commercial service tool: J-43897-18 or J-43897-12], and apply the anti-
seize lubricant (commercial service tool).

• Do not over torque heated oxygen sensor. Doing so may cause damage to heated oxygen sensor,

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.

INSPECTION AFTER INSTALLATION

• Make sure clearance between tail tube and rear bumper is even.
• With engine running, check exhaust tube joints for gas leakage and unusual noises.
• Check to ensure that mounting brackets and mounting rubbers are installed properly and free from undue

stress. Improper installation could result in excessive noise and vibration.
