If you are struggling with a PO420 code or noticed your engine has lost performance then it is time to clean your catalytic converter. Another way to confirm your catalytic converter could use good cleaning is to check your gas mileage to see if you are spending more at the pump than usual. Most people do not want to change the entire system when it is far easier to clean it. So here are some helpful tips to help you understand how to clean a catalytic converter so you can pass your emissions test.
It is important to understand before you begin the process the possible setbacks that can occur because the solvents used to clean your converter are very strong. There is the possibility that parts within your catalytic converter can loosen due to the products use. There is really no way to ensure these parts have come completely loose, but it is suggested to use a hammer and slightly tap while you listen closely for movement within the catalytic converter. If this does occur you are left with the only choice of replacing the system.
Now that we have discussed the dangers involved in the task of cleaning the system let’s focus on how to clean a catalytic converter. The most important task is researching which solvent mixture has the best reviews. It is important to invest in the best product available to ensure the task of cleaning the converter is successful. A great product with complies with VOC and OTC regulations. It is also important to make sure it complies with the Federal low sulfur content.
As simple as the process may seem it is very important to follow every step provided. Do not cut corners or leave your vehicle sitting once you have added the chemical mixture to your gas tank; this is the first step necessary to clean your catalytic converter. Once you have poured the mixture into your tank it is necessary to drive until your tank is almost empty. At this point, you can clear your vehicle of OBDII error codes if you have any that are showing. Now it is time to refill your tank and drive at least another 50 miles on the highway.
I am sure this is where you want to cut corners because you are tired of all the driving it took to cycle the cleaner through your system entirely. However, it is important to drive the little extra to ensure you have re-calibrated your onboard computer, also known as OBDII. If you have completed each step thoroughly then you should have no problem passing an emissions test. Your car will drive like it were new again, and you will feel great knowing you are repairing the damage that has been done to your vehicle thus far.
Remember to do your due diligence when you are choosing a catalytic converter cleaner. It is important to read through consumer reviews of others who have already purchased and successfully used the product. If you feel it is necessary to remove the catalytic converter before you choose to simply pour a cleaner into the gas tank and drive just make sure you use caution. Utilize protective eyewear, have clean towels on hand and use the proper size wrench to remove the catalytic converter. Then all you have to do is shake slightly while you listen for loose parts, and inspect openings thoroughly for melted plastic and other debris. If you find it is dirty and in need of cleaning you can use a pressure washer to spray it down. If that doesn’t clean it completely you can soak the catalytic converter in a mixture of degreaser and hot water.
