Catalytic Converter Break in

How to do a break-in procedure on a Catalytic Converter

When you replace a catalytic converter, you must conduct a special catalytic converter break in procedure. If you skip this step, you’ll destroy the new converter.

Here’s the catalytic converter break-in procedure:

• Start the vehicle, but do not rev the engine;

• Idle the vehicle and allow it to warm up slowly;

• After 5 minutes, increase the engine speed to 2500 rpm;

• Hold at 2500 rpm for 2 minutes; and

• Allow vehicle to cool down completely.
