A catalytic converter is used in vehicles to reduce the level of impurities arising from their emissions. It is quite possible for the converter to get destroyed because of external as well as internal factors ranging from accidents, inappropriate fittings and mishandling. Here are some of the most common catalytic converter symptoms for their failure.


Power Loss


Power loss is one of the most common catalytic converter symptoms. This occurs due to thermal failure and overheating. This happens when a huge amount of unused or raw fuel is in contact with the catalytic converter and burning takes place inside the converter. This way the fuel is restricted from reaching the engine. Due to this kind of leakage, excessive fuel could also result in heating the converter, which would lead to burning of ceramic monolith. The monolith is an integral part of the converter.


Going for a long drive in your car will certainly give you a wonderful experience, but if all the technical aspects of the car are not up to date, it can cause trouble to many. In order to maintain a car, you need to be careful about various aspects. One of them is catalytic converter symptoms. The basic use of this converter is to reduce the harm of the chemical gases that are released in the air by various cars, buses, trucks etc. With the help of this device only, the environment is also saved to a huge extent. If this chemical is not converted by this device, it can actually ruin the atmosphere and cause extreme situations for the people to even survive.

The main reason why people face problems with the catalytic converters is that they are not maintained properly. In order to keep the catalytic converter free from trouble you need to keep in mind certain important factors. It is important for you to be able to identify the defective catalytic converter symptoms if you want to prevent it from malfunctioning. There are various ways by signs, by which you can make out that your car’s catalytic converter is on the verge of breaking down. Some of the common symptoms of defective catalytic converter are briefly described below.


The main function of a catalytic converter, which lies in-between your car’s engine and exhaust is to remove harmful pollutants from the exhaust gases. The interior of this machine is honeycombed and is made up of rhodium, platinum and palladium coated ceramic compositions. This device is capable of changing air pollutants like nitrogen oxides into oxygen and nitrogen and carbon monoxide into carbon dioxide. It also has the power to change detrimental hydrocarbons into un-burnt gas, prior to discharging the emissions. The most effortlessly detectable sign is the deafening noise, which is produced due to the leaking of exhaust gases from a malfunctioning catalytic converter shell. The damage might be caused owing to an undercarriage event like a pebble bouncing off the catalytic converter. Few of the symptoms that can help you to check your catalytic converter are:


There are various types of catalytic converter symptoms for failure and you can easily identify these symptoms to ensure that you can go to the mechanic before the problem goes out of hand and the expenses of fixing the problem remains within the budget. The first and the most significant symptom is that of loss of power. When unused or excess raw fuel gets into the catalytic converter and burns there itself, it creates overheating causing thermal failure. Moreover, the fuel fails to reach to the engine thus confirming that there is some kind of leakage in the catalytic converter. Therefore, if you find that you are experiencing power failure you should check your catalytic converter.


The second most obvious symptom that your catalytic converter is failing is the high levels of emission from your car. This happens when your catalytic converter gets clogged with coolant or other material causing excess emission of hydrocarbons, nitrogen oxide and carbon monoxide. When you push on your accelerator and you see that your car is emitting gases more than it should it is a clear indicator that your catalytic converter is experiencing serious problems and requires your immediate attention. With regular excess emission, your catalytic converter is going to get clogged even more thus causing serious damage not only to your catalytic converter but also to your car.


Catalytic Converter Replacement

Catalytic converter replacement is not very difficult, but it may require a trip to the mechanic anyways. It’s usually only held on by a few bolts, but the nuts will be extremely difficult to take off. If you have access to air tools, then you may be in luck. You should still apply liberal amounts of penetrene or some other lubricant to help loosen the bolts. The bolts are notorious for stripping the studs as they are removed so be careful and take your time.


Catalytic converter replacement equipment

Catalytic converter replacement may require the use of welding equipment in which case most people will have to take their car to a muffler or exhaust shop in order to install the new one. You will need to raise your car to be able to replace the catalytic converter. You will also need a O2 sensor wrench because if you do the job without one you are likely never to get the sensor back in correctly. It’s also a good idea to make sure you have new gaskets in case you can’t reuse or tear the original ones as you remove the original catalytic converter.
