Removal and Installation

REMOVAL

Disconnect each joint and mounting.

Remove heated oxygen sensor 2 with following procedure: - Using heated oxygen sensor wrench [SST: KV10114400] (A), removal heated oxygen sensor 2 (1).

2 : Exhaust front tube

CAUTION:
Be careful not to damage heated oxygen sensor 2.

INSTALLATION


INSTALLATION

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

CAUTION:
Always replace seal bearings 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 anti-seize lubricant (commercial service tool).

Never over torque heated oxygen sensor 2. Doing so may cause damage to the 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 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 mounting 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.

Catalyst convertor to Exhaust Front Tube 1. Securely insert seal bearing (2) into catalyst convertor (1).

3 : Spring
4 : Nut
5 : Exhaust front tube

CAUTION:
Be careful not to damage seal bearing surface when installing.

2. 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 (3. After installing, check that stud bolt does not interfere with mounting ).


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

Exhaust Front Tube to Center Muffler


Exhaust Front Tube to Center Muffler 1. Securely insert seal bearing (2) into exhaust front tube (1) side in the direction shown in the figure.

3 : Spring
4 : Bolt
5 : Center muffler

CAUTION:
Be careful not to damage seal bearing surface when installing.

2. 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 ().
).

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

Inspection


Inspection

INSPECTION AFTER INSTALLATION

Check 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.
