Catalytic Converter - Gasoline Engines

Removal

NOTE: Some applications are equipped with a catalytic converter delete pipe in place of the underbody catalytic converter. The catalytic converter delete pipe mounts in the exhaust system the same way as the underbody catalytic converter. The catalytic converter delete pipe does not have a Catalyst Monitor Sensor (CMS).

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

2. If equipped, remove the skid plate.

3. Remove the 2 exhaust Y-pipe flange bolts.

4. Loosen the catalytic converter-to-muffler Torca(R) clamp or, if equipped, the catalytic converter-to-exhaust intermediate pipe Torca(R) clamp.

5. If equipped, disconnect the exhaust intermediate pipe isolator and the front muffler isolator.

6. Disconnect the catalytic converter from the isolator.

7. Remove the catalytic converter.

Installation

1. Position the catalytic converter into the muffler or, if equipped, the exhaust intermediate pipe.

2. If equipped, connect the exhaust intermediate pipe isolator, the front muffler isolator and the catalytic converter isolator.

3. Install the 2 exhaust Y-pipe flange bolts.
- Tighten to 40 Nm (30 lb-ft).

4. Make sure the button on the catalytic converter is fully inserted into the button slot on the muffler or, if equipped, the exhaust intermediate pipe and tighten the catalytic converter-to-muffler Torca(R) clamp or, if equipped, the exhaust intermediate pipe Torca(R) clamp.
- Tighten to 55 Nm (41 lb-ft).

5. NOTE: The exhaust system alignment procedure only needs to be carried out if the exhaust system isolators are not at zero load.

Check to see if the exhaust system isolators are at zero load. If the exhaust system isolators are not at zero load, carry out the exhaust system alignment procedure. For additional information, refer to Exhaust System Alignment - Gasoline Engines Service and Repair.

6. If equipped, install the skid plate.
