what are the symptoms of a bad catalytic converter in my Ford F-150 13th Generation (2015-2020)?

Solution

1. Preparation

• Gather necessary tools and parts.
• Park the vehicle on a level surface and engage the parking brake.
• Disconnect the battery negative terminal for safety.

2. Remove the Catalytic Converter

• Tools Required: Socket set, wrench, penetrating oil
• Apply penetrating oil to the bolts securing the catalytic converter to the exhaust system.
• Remove the bolts connecting the catalytic converter using the socket set and wrench.
• Carefully detach the catalytic converter from the exhaust system.

3. Inspect and Clean

• Check the catalytic converter for physical damage or clogging.
• If applicable, clean the exhaust pipe flanges and ensure they are free of debris before installation.

4. Install New Catalytic Converter

• Parts Required: New catalytic converter
• Position the new catalytic converter onto the exhaust system, ensuring proper alignment.
• Hand-tighten the bolts to hold the converter in place, then torque them to the manufacturer's specifications (typically around 30-40 lb-ft, but verify with the service manual).
• Reattach any heat shields or brackets that were removed.

5. Reconnect Battery and Test

• Reconnect the battery negative terminal.
• Start the engine and allow it to warm up, checking for exhaust leaks around the newly installed converter.
