If you are searching for the process on how to repair a catalytic converter, the following information will help. First, it is important to know that catalytic converters play an important role in making the air cleaner. With so many automobiles on the road, this car piece works to clean the air as you drive. With years of driving, the catalytic converter can become clogged with carbon and other foreign debris picked up from the outside environment.

Step 1: Decide what your Next Catalytic Converter will be

You may decide to pick up a new converter that is capable of having a higher flow of air through it. It will help you out a lot if you purchased a catalytic converter repair kit.

Step 2: Park your Vehicle on a Flat Surface

After the car is on level ground you can then proceed to jack the vehicle up to a desirable height point. The converter is located underneath the vehicle and you must be able to slide underneath it to go ahead with the repairs.

Step 3: Do Not Cut Material off the Down Pipe

Once you are at the point of looking at the catalytic converter located underneath the car you will see where the repairs are going to be made. Some of the pipes located around the part may be salvageable. Pipes with surface rust can be sandpapered down and this will save you money with your repairs. This is helpful because this is a do it yourself project.

Step 4: Use your Saw to Remove the Converter

You are now at the point where you can use a high powered saw to cut off the upper end of the converter. There is a bracket located at the lower end of the converter and this portion will not be sawed off. You can simply remove the bolts and you will see it can be removed easily. If you were to start your vehicle with the catalytic converter removed you will hear a loud noise coming from the vehicle. This shows how necessary it is to keep a functioning catalytic converter on a vehicle.

Step 5: You are now Ready to Add the New Converter

When you are securing the new catalytic converter to your vehicle there are a few options to help keep it in place. Aside from the nuts and bolts that have to be screwed on, high strength epoxy glue can keep the converter in place. Waterproof epoxy glue is available so be sure to purchase this type. You can buy the epoxy at auto stores and home improvement shops. Since the converter is ready to go back on and you will be sliding under again, check the jack to make sure it is still in place. Clean your salvaged pipes or collect the new ones that you purchased. Cut the pipes down so they fit in the area you sawed off. When you are ready, lift the converter up and secure in place. Use the epoxy glue to fill in any gaps that are visible to you. Once sealed, you have successfully finished the installation.
