We Americans love our cars and we rarely go anywhere without taking our 2 ton, gas-guzzling friend along with us. A catalytic converter helps to lessen the impact of automobiles on the environment. A catalytic converter controls the exhaust emission from an internal combustion engine by catalyzing a redox reaction. In 1975 the EPA made catalytic converters a requirement in vehicles that are manufactured in the United States.
Catalytic converters are an essential part of your car’s infrastructure. Without them, your car would never be able to pass its emissions test and you would leave a much bigger carbon footprint. You will find the converter in the exhaust system between the engine and the muffler.
How do you know when you have a bad catalytic converter?
Having a clogged catalytic converter will lessen your gas the mileage and reduce the engines overall performance. If you do not repair or replace a nonworking catalytic converter, it can destroy your engine.
In most cases, you will have to replace a catalytic converter when something goes wrong with it. However, you may be able to salvage the component. It is actually fairly simple to clean it on your own.
How To know if your Converter is Clogged
There are a few telltale signs that you have a bad or clogged converter in your car. None of these signs should ever be ignored.
If the fuel mixture is too heavy, the engine might misfire. If your engine misfires too often, it can cause melting metals in the converter which can clog it. If your car misfires often, there is a good chance something is wrong with your catalytic converter.
Looking for Problems
If your car rattles when it starts or if it takes its time to start, you may have a bad converter. If you smell a rotten egg or ammonia, you may have a bad converter.
Converters can become overheated due to large amounts of unburned gas. This may be caused when a spark plug misfires.
Checking for Trouble with a Scanner
If you own an OBD scanner, you can plug it in under your car's steering wheel. Your owner’s manual should have various codes for things that can go wrong in your car. To test your car, turn on the engine, but do not press the gas pedal. The scanner will show a code that will tell you where the problem is.
If there is black smoke coming out of the engine or if there is excessive heat coming from the car, the converter may be broken. If the unit itself is broken, you will have to replace it.
You will be able to clean your catalytic converter, so long as it is not overly clogged. If it is so clogged the engine won’t run at all, then you will probably have to replace it. You may be able to find a mechanic who specializes in your make and model of car who can unclog such a converter.
There is a good chance that your converter is simply cracked or broken. It may have been damaged by rocks and debris from the street or you may damage it driving over a curve. If a converter is broken or cracked, it will need to be replaced and not repaired.
Sometimes there is damage to the catalytic converter that is caused by other issues within the car. If there is a fuel leak in the vehicle’s engine, fuel may get into the cylinders and get burned inside the catalytic converter.
Unclogging The Catalytic Converter
You can find a can of catalytic converter cleaner in any automotive supply store or in the automotive section of your local grocery store. You can also go online where you will be able to find the perfect brand for the make and model of your car.
- Drive your car until there are about 15 liters of gas in it. Do not attempt to clean your converter with less than this amount of gas in the tank.
- Pour the cleaner into the gas tank. The instructions on the bottle should tell you how much cleaner to use.
- Replace your gas cap and drive your vehicle for half an hour and try to go to a highway if necessary. You should drive until the tank is close to empty. The engine should not overheat.
- Clear the OBD code and let it calibrate. Then do a reading of the converter again.
If your converter is not terribly clogged, this method should work. If the code is still showing that there is something wrong with your converter, there is another way to unclog the converter.
Removing the Catalytic Converter
If you have some mechanic skills and if your converter is clogged beyond the point of being unclogged with cleaner from the store, you can try taking the converter out and cleaning it.

Inspect the Converter
Shake the converter gently and listen for anything broken inside. If there is something broken inside, or if the converter looks as though it has melted, you will want to get it replaced.
Cleaning the Cat-Con

Combine hot water and degreaser inside a large container. let the cat-con soak for 45 minutes to two hours. Take it out of the container, rinse it off, and let it dry.
Put the Converter Back Into the Car
Once the converter is completely dry you can put it back into the car remembering to securely fasten it when you do. Once again, you should go for a drive to test the component. After driving on the highway and nearly using all the gas, re-test the converter and make sure it falls into the proper ranges. If it does not, you will have to replace the converter.
Remember that a converter is crucial to your car’s performance an getting it checked out should be a top priority if you think anything is wrong with it.

Selling your car online can be dangerous. Criminals have found victims online using electronic billboards for years.
File an Insurance Claim
If your converter was destroyed in an accident, you may be able to get the insurance company to pay for repairs or a new car. There are two kinds of insurance rules in the united states; fault and no-fault. In a fault state, the person who caused the accident is responsible for paying its related bills. In a no-fault state, a person’s own insurance company pays for their bills no matter who caused the crash.
When you have an accident, you will file a claim. If the damages to your car exceed a good portion of the amount of money that car is worth, it will be considered totaled. If the car is totaled, your insurance company is supposed to pay you what it was worth right before the collision.
There are no regulations for determining how much any car is worth. It is up to the insurance company to decide the car’s worth. The insurance company wants to keep its money in-house and they are unlikely to give you a good price.
You can either take the settlement, or you can hire an attorney to negotiate on your behalf. A lawyer will keep a large percentage of that money.
Trade-In Your Car
If you are going to buy a new car, the salesperson at the dealership will be able to give you a trade-in allowance for your old vehicle. Normally, they will offer you less than the car is worth.
In some cases, a dealership may give you a good trade-in allowance. If they do this, you should read your final offer very carefully. They may try to put the money that they gave you right back on to the final price of your new vehicle.
When you go into the dealership, do not tell them that you have a car to trade-in. Get the salesperson to give you a final price in writing and then tell them about the trade-in.
