Removal

NOTE: Always install new fasteners and gaskets. Clean flange faces prior to new gasket installation to make sure of correct sealing.

1. With the vehicle in NEUTRAL, position it on a hoist.

2. Remove the RH front wheel and tire.

3. Disconnect the RH Heated Oxygen Sensor (HO2S) electrical connector.
- Detach the HO2S (Heated Oxygen Sensor) electrical connector retainer from the bracket.


4. Remove the LH and RH exhaust flexible pipes. For additional information, refer to Exhaust Flexible Pipe- LH and Exhaust Flexible Pipe- RH .

5. Disconnect the RH Catalyst Monitor Sensor (CMS) electrical connector.

6. Remove the 3 RH catalytic converter-to-turbocharger nuts and the converter.
- Discard the nuts and gasket.


Installation

1. Inspect the RH turbocharger-to-catalytic converter studs for damage.
- If damaged or if a stud comes out when removing the nut, replace the stud.

- Tighten to 25 Nm (18 lb-ft).


2. NOTICE: Failure to tighten the RH catalytic converter manifold-to-turbocharger nuts to specification a second time will cause the RH catalytic converter manifold-to-turbocharger to develop an exhaust leak.

NOTICE: Prior to installation, inspect the HO2S (Heated Oxygen Sensor) and the CMS (Catalyst Monitor Sensor) wiring harness for damage.

Using a new gasket and 3 new nuts, install the RH catalytic converter manifold to the turbocharger. Tighten the RH catalytic converter manifold in 2 stages.
- Stage 1: Tighten to 40 Nm (30 lb-ft).

- Stage 2: Tighten to 40 Nm (30 lb-ft).


3. Connect the RH Catalyst Monitor Sensor (CMS) electrical connector.

4. Install the LH and RH exhaust flexible pipes. For additional information, refer to Exhaust Flexible Pipe- LH and Exhaust Flexible Pipe- RH .
