Solution

1. Preparation

• Gather necessary tools and parts.
• Park the vehicle on a level surface and engage the parking brake.
• Allow the engine to cool down before beginning work.

2. Remove Exhaust Components

• Sub-steps:
  1. Disconnect the negative terminal of the battery.
  2. Raise the vehicle using a jack and secure with jack stands.
  3. Locate the catalytic converter on the exhaust system.
  4. Remove any bolts or clamps securing the catalytic converter to the exhaust pipe and exhaust manifold using a socket set.

  2. If replacement is necessary, install the new catalytic converter in reverse order of removal.
  3. Ensure all gaskets and seals are properly seated.
  4. Tighten bolts to the manufacturer's torque specifications (usually around 25-35 ft-lbs, but verify for your specific model).
  5. Reconnect the negative terminal of the battery.

4. Test the System

• Sub-steps:
  1. Start the engine and allow it to idle.
