What do you need to do for the break in for the catalytic, treatment ect..??Eugene B.Sep 24, 2020
Best Answer:Hi- How to Break In a New Catalytic Converter(excert from technical notes) To start the break-in procedure, start the car after you’ve replaced the cat. Let the car idle in place without applying any gas. When the engine warms up to its operating temperature, get inside and give the car enough gas to bump the RPMs to around 2500. Hold it there for 2 minutes and then release the gas. Shut the car off and let it cool down completely. And that’s your entire catalytic converter break-in procedure. The reason why cats need to be broken in before use, comes down to gradually exposing the new components to high heats and pressures. This initial warm-up phase allows all the materials inside the catalytic converter to set in place. Performing a new cat’s gradual warm-up is also necessary to burn off the binding that keeps the matting compressed. If you were to subject the new cat to an average drive, or even worse, a more dynamic drive, you’d most likely end up with dislodged components within the cat housing. Considering how expensive cats are, that would be one pretty costly mistake. You’d be surprised how many brand new catalytic converters are ruined because people are never told how to break them in properly. You’ll save yourself a lot of trouble by following this extremely simple and fast break-in procedure.
