Special Tool(s):

Material:

Removal
1. With the vehicle in NEUTRAL, position it on a hoist.
2. Remove the exhaust flexible pipe.
3. Remove the exhaust gas recirculation (EGR) tube.
4. Disconnect the heated oxygen sensor (HO2S) and catalyst monitor sensor (CMS) electrical connectors.
5. Remove the 2 bolts and the RH catalytic converter manifold shield.
6. Remove the 2 RH catalytic converter manifold shield bracket bolts and the shield bracket.
7. Loosen the 2 RH catalytic converter manifold bracket bolts.
8. Remove the 6 nuts and the RH catalytic converter manifold.
^ Discard the 6 RH catalytic converter manifold nuts and gasket.

9. Remove the 6 RH catalytic converter manifold studs and discard.

10. NOTE: If installing a new RH catalytic converter manifold, remove and save the HO2S and CMS for installation in the new RH catalytic converter manifold.

Using the special tool, remove the RH catalytic converter manifold HO2S and CMS.





11. Clean and inspect the manifold.

Installation

1. NOTE: Apply anti-seize lubricant to the threads of the HO2S and CMS before installation.

If installing a new RH catalytic converter manifold, install the HO2S and CMS using the special tool.
^ Tighten to 47 Nm (35 ft. lbs.).





2. Install the 6 new RH catalytic converter manifold studs.
^ Tighten to 11 Nm (8 ft. lbs.).

3. Position a new RH catalytic converter manifold gasket on the studs.

4. CAUTION: Failure to tighten the catalytic converter nuts to specification before installing the converter bracket bolts will cause the converter to develop an exhaust leak.

CAUTION: Failure to tighten the catalytic converter nuts to specification a second time will cause the converter to develop an exhaust leak.

NOTE: Make sure to tighten the nuts in the sequence shown in 2 stages.

Position the RH catalytic converter manifold and tighten the 6 new nuts in the sequence shown, in 2 stages.
^ Stage 1: Tighten to 20 Nm (15 ft. lbs.).
^ Stage 2: Tighten to 20 Nm (15 ft. lbs.).





5. Install the shield bracket and the 2 RH catalytic converter manifold shield bracket bolts.
^ Tighten to 20 Nm (15 ft. lbs.).

6. Tighten the 2 RH catalytic converter manifold bracket bolts.
^ Tighten to 20 Nm (15 ft. lbs.).

7. Position the RH catalytic converter manifold shield and install the 2 bolts.
^ Tighten to 10 Nm (89 inch lbs.).

8. Connect the HO2S and CMS electrical connectors.
9. Install the EGR tube.
10. Install the exhaust flexible pipe.
