Special Tool(s):

Material:

Removal
1. With the vehicle in NEUTRAL, position it on a hoist.
2. Remove the 5 bolts and the passenger side splash shield.





3. Disconnect the LH heated oxygen sensor (HO2S) and the LH catalyst monitor sensor electrical connectors.
4. Using the special tool, remove the H02S.





5. CAUTION: Do not allow the exhaust Y-pipe to hang from the flexible end. Support the exhaust Y-pipe or damage to the exhaust system may occur.

Remove and discard the 4 exhaust Y-pipe nuts and position the exhaust Y-pipe aside.
^ Discard the gasket.
6. Remove and discard the 6 LH catalytic converter manifold nuts.
7. Remove the LH catalytic converter from the vehicle.
^ Discard the LH catalytic converter manifold gasket.
8. Remove and discard the 6 LH catalytic converter manifold studs.
9. Clean and inspect the LH catalytic converter manifold.

Installation
1. Install the 6 new LH catalytic converter manifold studs.
^ Tighten to 11 Nm (8 lb-ft).
2. Position a new LH catalytic converter manifold gasket.

3. 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 in 2 stages.

Position the LH catalytic converter and tighten the 6 exhaust manifold nuts in 2 stages in the sequence shown.
^ Stage 1: Tighten to 25 Nm (18 lb-ft).
^ Stage 2: Tighten to 25 Nm (18 lb-ft).





4. Position the exhaust Y-pipe gasket.
5. Position the exhaust Y-pipe and install the 4 new exhaust Y-pipe nuts.
^ Tighten the nuts to 47 Nm (35 lb-ft).

6. NOTE: Make sure to apply anti-seize lubricant to the threads of the HO2S before installation

Using the special tool, install the HO2S.
^ Tighten to 47 Nm (35 lb-ft).





7. Install the passenger side splash shield and the 5 bolts.





8. Connect the LH HO2S and catalyst monitor sensor electrical connectors.
