Subaru Outback Catalytic Converter

Three Tips to Keep Your Subaru Outback Catalytic Converter in Top Condition

An essential part of your vehicle's exhaust system, the Subaru Outback catalytic converter reduces harmful compounds from the exhaust gases. The combustion reaction is responsible for this process, which happens in the interior honeycomb system of your catalytic converter. However, your catalytic converter can be prone to damage and wearing out because of the possible contaminants that may enter its system. Thus, you must know how to maintain this crucial part. Here are some tips that you can follow:

  • Use a degreaser to prevent contaminants from entering your catalytic converter.

You must keep your catalytic converter clean at all times, so contaminants will not be able to enter it. You can use a mixture of degreaser and warm water for spraying your catalytic converter. The degreaser is effective in cleaning metal parts, and can dissolve thick oily substances that have formed on any surface. You can also make use of a soft cloth in wiping your catalytic converter to prevent dirt from reaching it further.

  • Constant driving at highway speeds can keep your catalytic converter working efficiently.

You must also take note of your driving habits to protect your catalytic converter. It is recommended to run your engine at a speed intended for highway driving, which must be practiced regularly as much as possible. This is because short drives are not enough to let your catalytic converter have enough heat for burning fuel in its interior honeycomb system. In addition, you should let your engine be heated enough at regular intervals especially during cold season. This is because multiple cold starts can cause your catalytic converter to wear out.

  • Use a safe fuel cleaner for enhanced protection.

You can make use of a fuel cleaner for the inner contents of your catalytic converter. However, choose a cleaner that is safe for the honeycomb converter, and that allows the reduction of harmful exhaust gases. The fuel cleaner can enable your catalytic converter to function more smoothly, and can prevent it from being clogged and contaminated.

  • Identifying the Root Causes behind the Problems in Your Subaru Outback Catalytic Converter

    Your Subaru Outback catalytic converter is responsible for reducing toxic gases that are emitted through internal combustion. It contains a honeycomb, which acts as a barrier that removes harmful substances from exhaust gases before they escape your vehicle. This important part of the exhaust system needs to be maintained at all times because its performance can greatly affect the engine. However, it can wear out due to several causes. Here are the common signs that you must watch out because they can indicate a faulty catalytic converter:

    Misfiring engine

    If you experience a misfiring engine, your catalytic converter may be clogged. Misfiring means that the fuel fails to ignite properly, which causes your engine to buck or jerk once you turn it on. This usually occurs when raw fuel gets mixed with the excessive rich fuel in your catalytic converter. As a result, your catalytic converter will be clogged because the gases will not be able to escape.

    Decrease in fuel economy

    If you notice that your vehicle consumes more fuel than the usual, the root cause might also be a clogged catalytic converter. The problem is also evident when you step on your accelerator but your ride does not go any faster. This is because if your catalytic converter is heavily blocked with the exhaust gases, it will increase the chances of back pressure to develop. As a result, your engine will have a conflict increasing its speed because of the back pressure that is resisting it.

    Rotten smell

    There is a noticeable foul smell that you might also encounter, which is a sign of a defective catalytic converter. This usually happens because of the excessive fuel that enters in your catalytic converter. Take note that gasoline contains sulfur, so it can produce a rotten smell if it is mixed with the excessive fuel. Moreover, the problem can cause your catalytic converter to melt down because the concentration of the sulfur tends to be higher. So if your catalytic converter melts down, it can cause fuel to escape. The leaking fuel can also be the source of the foul smell, which is similar to rotten eggs.
