2. Disconnect the heated oxygen sensor electrical connector.
3. Disconnect the rosebud clip from the bracket above the starter motor.
4. Remove the heated oxygen sensor from the left side catalytic converter.



5. Remove the nuts attaching the catalytic converter to the exhaust manifold.



6. Remove the bolts that attach the left side catalytic converter to the right side catalytic converter.



7. Remove the left side catalytic converter from the vehicle.

1. Install the left side catalytic converter to the vehicle.



2. Install the bolts that attach the left side catalytic converter to the right side catalytic converter.

Tighten
Tighten the catalytic converter bolts to 25 N·m (18 lb ft).

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.




3. Install the nuts that attach the left side catalytic converter to the exhaust manifold.

Tighten
Tighten the nuts to 30 N·m (22 lb ft).

Tighten
Tighten the heated oxygen sensor to 42 N·m (31 lb ft).

5. Attach the rosebud clip to the bracket above the starter motor.
6. Connect the heated oxygen sensor electrical connector.
7. Lower the vehicle.
