EXHAUST SYSTEM

• Discard any heated oxygen sensor 2 which has been dropped onto a hard surface such as a con-

crete floor. Use a new one.

• Before installing a new heated oxygen sensor 2, clean exhaust system threads using the heated oxy-

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

• Never over torque heated oxygen sensor 2. Doing so may cause damage to the heated oxygen sen-

sor 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 gas

leakage.

• When installing each mounting rubber, use silicon oil to avoid twisting.
• Temporarily tighten mounting nuts and bolts. Check each part for unusual interference and mount-

ing rubber interference, and then tighten them to the specified torque.

• When installing each mounting rubber, avoid twisting or unusual extension in up/down, front/rear

and right/left directions.

Exhaust Manifold to Exhaust Front Tube

Securely insert seal bearing (2) into exhaust manifold (1) side in
the direction shown in the figure.

CAUTION:

Be careful not to damage seal bearing surface when install-
ing.

With spring, tighten nut.

CAUTION:

• Fasten stud bolts to the flange of exhaust manifold side to the specified torque before fastening

mounting nuts.

• Ensure springs are seated correctly on the flange and not sitting on (A).
• Be careful that stud bolt does not interfere with mounting hole of exhaust front tube (

After installing, check that stud bolt does not interfere with mounting hole of exhaust front tube.

Exhaust Front Tube to Center Muffler

Securely insert seal bearing (2) into exhaust front tube (1) side
in the direction shown in the figure.

CAUTION:

Be careful not to damage seal bearing surface when install-
ing.

With spring, tighten bolt.

CAUTION:

• Ensure springs are seated correctly on the flange and not sitting on (A).
• Be careful that bolt does not interfere with mounting hole of center muffler (

After installing, check that bolt does not interfere with mounting hole of center muffler.
