Three Tips to Keep Your Chevrolet Cobalt Catalytic Converter in Top Condition

Your Chevrolet Cobalt is designed to achieve maximum performance through its systems that work together. One of which is the exhaust system, where your catalytic converter is found. It functions by filtering the harmful emissions and turn them into less toxic gases, which are released into the atmosphere. However, your catalytic converter is prone to overheating and wearing out because of corrosive substances. Thus, you must keep it in top condition and clean at all times. Here are some helpful tips that you can follow for maintaining and prolonging the life of your catalytic converter:

  • Keep the catalytic converter clean.

You can do this by using the "tap and wipe" technique. By using a tool or just one of your hands, tap the catalytic converter to loosen any dirt particles and surface debris. After tapping, you may use a cloth to wipe the surface to remove the remaining dirt, grease, and other small particles.

  • Maintain your engine together with your catalytic converter.

To prevent your catalytic converter from wearing out, you must maintain your engine as well. Always check if the engine oil is still enough. In addition, follow the scheduled tune-ups of your engine. If your catalytic converter is blocked because of excess back pressure, then your engine performance will be affected. Moreover, if your engine overheats, your catalytic converter can be burnt out. Thus, you must inspect and maintain these components regularly to avoid these problems.

  • Check your exhaust system regularly.

You have to check your exhaust system and the oxygen sensors regularly so that you can avoid clogging and damaging your catalytic converter. These components regulate the air-fuel mixture, so they must also be kept in top condition at all times.

  • Make use of a catalytic converter cleaner.

This cleaning substance is recommended for maintaining components of your vehicle, including the engine, fuel tank, and your catalytic converter. It can also help clean the interior parts, including your oxygen sensors and the fluids in your vehicle. You can use this product at least four times a year, so you can provide additional tune-ups for your vehicle.

Your Chevrolet Cobalt is equipped with an efficient catalytic converter, which functions by altering the fuel residues into less toxic gases before emission. In addition, your catalytic converter works by regulating the combustion that occurs in your engine system. However, if your catalytic converter seems to malfunction, you must be able to detect the common symptoms to prevent further damage. Here are some situations that you may encounter with your Chevrolet Cobalt catalytic converter:

Misfiring engine

Misfiring means that your engine fails to work properly because the fuel mixture burns excessively. Thus, your catalytic converter overheats. The fuel mixture goes through exhaust valves that regulate their flow. However, if the valves are burned or worn out, then misfiring will occur. The fuel will be clogged, so it will not be able to enter your catalytic converter. As a result, the toxic fuel will not be eliminated from your vehicle. To see if your catalytic converter is malfunctioning, you must check if the performance of your engine is deteriorating. Check your fuel economy if it is decreasing as well.

Increased carbon production

If your catalytic converter wears out too fast, you must check your exhaust system. The common cause behind this is the impurity of chemicals found inside your catalytic converter. As a result, there will be an increased level of carbon production. This gas is not just harmful to your vehicle but also to the atmosphere when emitted. The excessive carbon emission can also result in internal damage and overheating of your engine.

Drop in gas mileage and rotting smell

If there is a noticeable drop in your gas mileage, then you must check your catalytic converter. This is an indication of clogging. If the fuel mixture is blocked from exiting your exhaust system, then your catalytic converter will have more back pressure. As a result, your gas mileage will decrease. A clogged catalytic converter also causes a foul smell. This is due to the fuel that is not burned properly, which in turn builds up pressure in the internal chambers of your catalytic converter.
