A catalytic converter is an air pollution control device that converts harmful gases in the exhaust to less toxic substances. It does this by using a chemical process called oxidation, which requires oxygen and fuel (this could be gasoline or diesel).
The oxidization reaction made possible by the catalyst itself produces additional energy in the form of heat. This heating effect may cause some other responses, often resulting in toxic fumes being produced. Thus, the role of the catalytic converter is to shift harmful emissions into more minor toxic forms so that they can be quickly expelled from your vehicle’s tailpipe.
Why do you need to replace the catalytic converter?
Catalytic converters are critical because they reduce toxic ingredients in car exhaust, such as benzene, formaldehyde, and butylene’s. The only problem with a catalytic converter is that it gets saturated with toxins. When this happens, cars require the replacement of their catalytic converters.
To get rid of the toxins trapped within a catalytic converter, a chemical process called oxidation needs to occur. This process requires exposure to certain chemicals which will oxidize the toxins inside your cat. Once the oxidation process takes place, these will absorb all these toxins from the catalytic converter, resulting in a significant reduction of the levels of toxins in automobile exhaust.
How much does it cost to repair a catalytic converter?
The prices of catalytic converter repairs vary according to the make and model cars. And also, it depends on whether or not you are choosing to repair your cat yourself or by seeking help from a repair shop.
However, if you take your car to an auto repair shop, you should be ready for at least $200-$500 costs that will come with replacing your entire catalytic converter. There exists one guide in which it takes less than $100 just for parts, excluding labor charges which can be around $80-$100 depending on where you live and what part of the country you live in.
How to fix catalytic converter without replacing?
1. Remove the old catalytic converter
Removing the old catalytic converter is very important because it contains many toxins that might still affect your engine if left unchecked. To make sure that there are no traces of these toxins left on your car, you have to wipe off everything, including the undercarriage of your vehicle, with some washing materials.
This is necessary to remove all signs of corrosion caused by these toxins. Some people advise that you can wash off your car with warm water since using hot water will only melt away more metal on your cat, which you do not want to happen. So always remember to use cold water not to damage any part of your cat further, even more than before.
2. Flush out the catalytic converter
The next step is to flush out your cat with hot water. Get a garden hose and turn on your tap’s cold mode. Next, bring it near the end of the exhaust pipe, then let hot water flow into it. Flushing out your cat with hot water might prove to be very effective since it will start melting away any residue left inside.
If you notice some chunks come out of this process, make sure you wash them off immediately before they melt more metal on your cat, which will result in corrosion again. After doing this, do another round of oxidation process using chemical agents or incinerators depending on what type of treatment you have for your car.
3. Catalytic converter
Replacing your catalytic converter is not necessary because you have already done two steps before returning it. The only time you need to replace your cat is when the oxidation process has taken place, but there are still build-ups of metal left inside the upholstery, so this will require replacement.
4. Check and change the oil
After all, these, make sure that you check and change the oil in your engine to remove any remaining toxins which might cause corrosion on your machine. If your motor oil looks clean enough without traces of other materials, then this means that the last step was successful. These steps will help prolong the life of your car since it also helps reduce other issues that may arise, such as clogged air filters and other parts due to the build-up of these toxins.
These steps can be done at home, and you do not need any professional help to do it, which means that you save a lot on labor costs when doing this yourself. The materials required for these procedures are also available in your local hardware store, so there is no need to buy them from other sources such as online shops where prices tend to add up, especially with shipping fees.
The idea of how to fix catalytic converter without replacing comes directly from you taking the initiative and responsibility for the state of your car’s air quality and potential results if left untreated, which might end up very expensive in terms of replacement costs and time inconvenience caused by having your curable for a few days (especially if you are using your car in the line of work). Always remember that prevention is better than cure.
5. Clean and polish exhaust pipe
Cleaning and polishing the exhaust pipe might not be necessary to do during these procedures, but it is a necessity whenever you have to replace your catalytic converter. This step is significant because if not done correctly, you could end up with issues like poor gas mileage and other problems that might result from this, such as overheating the engine.
It does not require any special knowledge or tools; it requires patience since this process takes time, especially when using sandpaper. It would help if you also were careful in avoiding scratches to avoid further damage over the metal surface.
