Solution

1. Preparation

Tools Required: Socket set, torque wrench, O2 sensor socket, pry bar, jack and jack stands, exhaust hanger removal tool.
Disconnect the battery to prevent any electrical issues during the repair.
Raise the vehicle using a jack and secure it with jack stands.

2. Remove Exhaust Components

Sub-steps:
1. Remove the exhaust heat shield if present, using a socket set.
2. Loosen the bolts securing the catalytic converter to the exhaust manifold and the exhaust pipe using a socket set.
3. Use an exhaust hanger removal tool to detach any hangers holding the catalytic converter in place.

3. Remove the Old Catalytic Converter

Sub-steps:
1. Carefully slide the catalytic converter out of its mounting location.
2. Inspect the gaskets and any seals for wear or damage; replace as necessary.

4. Install the New Catalytic Converter

Sub-steps:
1. Position the new catalytic converter in place, ensuring it aligns with the exhaust manifold and the exhaust pipe.
2. Install new gaskets to ensure a proper seal.
3. Tighten the bolts securing the catalytic converter to the exhaust manifold and the exhaust pipe to the manufacturer’s specifications (typically 16-22 lb-ft).
4. Reattach the exhaust hangers that were removed.

5. Reinstall Components

Sub-steps:
1. Reinstall the exhaust heat shield if it was removed.
2. Reconnect the battery.
