Solution

1. Preparation

Tools Required: Socket set, jack and jack stands, O2 sensor socket, exhaust hanger tool, safety gloves, safety glasses.
Lift the vehicle using a jack and secure it with jack stands.
Disconnect the battery negative terminal to prevent any electrical shorts.

2. Remove Exhaust Components

Sub-steps:
1. Using the socket set, remove the bolts connecting the exhaust pipe to the catalytic converter.
2. If applicable, disconnect the O2 sensors from the catalytic converter using the O2 sensor socket.
3. Use the exhaust hanger tool to detach any hangers holding the exhaust system in place.
4. Carefully slide the catalytic converter out of its mounting position.

3. Install New Catalytic Converter

Sub-steps:
1. Position the new catalytic converter in place and ensure it aligns with the exhaust pipe and mounting points.
2. Reinstall the O2 sensors into the new catalytic converter, ensuring they are properly seated.
3. Secure the catalytic converter to the exhaust pipe using the original or new bolts. Torque to manufacturer specifications (refer to the service manual for exact torque values).

4. Reassemble Exhaust System

Sub-steps:
1. Reattach any exhaust hangers that were removed during the disassembly.
2. Double-check all connections for tightness and proper alignment.
3. Reconnect the battery negative terminal.

5. Final Inspection

Sub-steps:
1. Start the engine and let it idle for a few minutes to check for any exhaust leaks.
2. Monitor the check engine light to see if it remains illuminated.
3. Conduct a test drive to ensure proper operation and performance.
