CAUTION:

Do not remove the heated oxygen sensor 2 from the front exhaust tube unless necessary for replacement of the heated oxygen sensor 2. If the heated oxygen sensor 2 is removed from the front exhaust tube, it must be replaced with a new one.

Note:

Heated oxygen sensor 2 replacement or removal from the front exhaust tube is not necessary when removing or repositioning the front exhaust tube. Disconnect the harness connector from the heated oxygen sensor 2 and remove or reposition the front exhaust tube and the heated oxygen sensor 2 as an assembly.

Removal and Installation

Removal and Installation

REMOVAL

Disconnect each joint and mounting rubber.

• Remove heated oxygen sensor 2 (1) using Tool (A).

  

  : Front

  Tool number (A)

  : KV10114400 (NI-38365)

  CAUTION:

  • 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, use a new one.

  • Before installing new heated oxygen sensor, clean exhaust system threads using oxygen sensor thread cleaner and approved anti-seize lubricant.

  Oxygen sensor thread cleaner	: — (NI-43897-12)
  Oxygen sensor thread cleaner	: — (NI-43897-18)

INSTALLATION

Installation is in the reverse order of removal.

CAUTION:

• Do not reuse seal bearing.

• Do not reuse plate gasket.

• 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 oxygen sensor thread cleaner and apply anti-seize lubricant.

• 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 preventives from adhering to the sensor body.

• 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 fume leaks.

• When installing each mounting rubber, use silicon oil to avoid twisting.

• Temporarily tighten 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.

Exhaust Manifold to Exhaust Front Tube

Securely insert plate gasket (2) into exhaust manifold (1) in the direction shown.

(3)	: Stud bolt
(4)	: Exhaust front tube
(5)	: Nut

CAUTION:

Do not reuse plate gasket.

Be careful not to damage plate gasket surface when installing.

Install exhaust front tube and tighten nut.

CAUTION:

• Fasten stud bolts to the flange of exhaust manifold side to the specified torque before installing nuts.

• Be careful that stud bolt does not interfere with hole of exhaust front tube.

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

Exhaust Front Tube to Exhaust Main Muffler

Securely insert seal bearing (3) into exhaust front tube (1) in the direction shown.

(2)	: Stud bolt
(4)	: Exhaust main muffler
(5)	: Nut

CAUTION:

Do not reuse seal bearing.

Be careful not to damage seal bearing surface when installing.

Install exhaust main muffler and tighten nut.

CAUTION:

• Be careful that stud bolt does not interfere with hole of main muffler.

After installing, check that the stud bolt does not interfere with hole of main muffler.

INSPECTION AFTER INSTALLATION

Check clearance between tail tube and rear bumper is even.

With engine running, check exhaust tube joints for gas fume leaks 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.
