Subaru Forester Catalytic Converter

How to Keep Your Subaru Forester Catalytic Converter in Its Top Form

Your Subaru Forester catalytic converter functions by burning gas in the exhaust system of the vehicle so that fresh air can be brought into the system. It is specially designed to have maximum efficiency since it prevents gas clogging in the exhaust system. Now, because of this critical function, it is highly important to maintain this engine part for better performance. Here are some tips to help you get started:

  • Clean the catalytic converter personally.

You can maintain your car's catalytic converter by easily cleaning it yourself. All you need is a cloth or sponge, hot water, and a power spray. These can help you remove the dirt and grease from the surface of the converter.

  • Remove the catalytic converter to check its condition.

The catalytic converter can be removed for you to check excessive hydrocarbon to avoid congestion of gas. If there is a rattling sound when you shake the catalytic converter, then there is a gas build-up internally. Thus, you should let the converter to be dried out of too much gas, or use an air hose with high pressure.

  • Use your vehicle consistently.

If you need to drive in the city, it is better to keep the engine running at a suitable highway speed, preferably for longer hours at regular use. The catalytic converter needs heat, which is high enough to burn gas in the exhaust system. So it is better to avoid cold starts and keep the heat condition of the engine at a stable level for the converter to work efficiently.

  • Observe engine tune-up.

Keep in mind that tune-up is a must for maintenance. The cylinders of the catalytic converter must have enough heat in order to burn excess gas, which can prevent better engine performance. Make sure that you are able to follow scheduled maintenance of your engine system.

If you think that your car needs professional handling, be sure that the people in charge have the right tools for your Subaru Forester catalytic converter. It is better to have your catalytic converter checked as much as possible because a well-maintained one will be able to save more gas, thus this will allow you to enjoy savings as well.

  • Troubleshooting Usual Subaru Forester Catalytic Converter Issues

    The catalytic converter can be considered as a filter. Why? It functions by converting damaging compounds in the engine system into less harmful gases before being released in the atmosphere. Luckily, this car part can last for a long period of time, but it is still important for it to be checked and monitored. The Subaru Forester catalytic converter is made from high-quality catalytic case and is equipped with durable heat protection. But still, there are problems that you may encounter with your catalytic converter as time progresses. It is important that you know how to detect those problems and be able to troubleshoot them.

    Overheating of catalytic converter

    This can be detected when there is a misfiring or a shaky feeling when you run your engine. Overheating is usually caused by the excessive fuel mixture on the pipes of the catalytic converter. To troubleshoot, you should check the exhaust system in general, as well as the oxygen sensors which regulate the flow of air and fuel.

    Back pressure in the catalytic converter

    This is similar to overheating, as back pressure is caused by an exhaust blockage. It means that air from the exhaust cannot escape, thus fresh air is blocked from coming in. You can use a vacuum test in order to determine if there is still a back pressure in the catalytic converter. If the reading of pressure stabilizes, then the converter is back to its normal operation.

    Cookout of catalytic converter

    This is worse than overheating because when there is an exhaust leak, your catalytic converter can be burnt. Thus, it is really important to have regular maintenance of the engine system, aside from choosing quality gasoline or fuel for your car.

    Other parts to be considered

    Along with the catalytic converter are the PCV valves and the EGR systems, which are also vital to be checked when you are troubleshooting.

    • PCV Valves: The PCV (Positive Crankcase Ventilation) valves have spring tension which should be enough because little or too much tension can affect the oil levels in the combustion system.
    • EGR Systems: EGR (Exhaust Gas Recirculation) systems function as nitrous oxide blockers, which allow the regulation of combustion temperature. If EGR systems are clogged, then pressure could be built, which can cause engine misfire and can damage the converter.
