A catalytic converter is an important part of recent cars, as it purifies your vehicle’s exhaust gases and thus matches modern pollution requirements. However, it is possible that it may become clogged or breakdown, in which case a change or cleaning is essential. In this article we are going to look at how to clean a catalytic converter on Subaru Legacy? To do this, to begin with, we will explain the situations in which it may be interesting to clean the catalytic converter of your Subaru Legacy, then, how to perform this cleaning to recover the efficiency of the catalytic converter of your car.
Why would you want to clean up the catalytic converter of your Subaru Legacy?
In this first section we will show you why it may be important to clean the catalyst of your Subaru Legacy . In fact for some of you it might seem obvious but the majority of you do not understand how it works and the consequences dirty catalytic converter .
Purpose and functioning of the catalytic converter of a Subaru Legacy
.
The catalytic converter of your Subaru Legacy has the objective to get rid of harmful exhaust gases related to the process of your engine. In fact, it is one of the most important parts that fight against the pollution discharged by your Subaru Legacy. It will convert these harmful gases into water or non-polluting gases. In order to convert these gases, the catalyst of your Subaru Legacy a mesh of precious metals which, when the gases pass at high temperature, will break them down by chemical reaction . A catalytic converter can just work from 400°, it is consequently necessary to avoid clogging the catalytic converter of your Subaru Legacy. If you are thinking of making sufficiently long trips to heat it up frequently (count more than 10 kilometres for the catalyst to reach the right temperature), this will enable you to optimize the life of this component and maintain ideal engine performance.
Outcomes of a dirty or faulty catalytic converter on Subaru Legacy
We will now discover what can be the consequences of a dirty or failing catalytic converter on Subaru Legacy . This will enable you to establish the signs of illness that should warn you to a malfunction of your catalytic converter, here is the list of symptoms of a faulty catalytic converter:
- The catalytic converter of your Subaru Legacy is clogged: As we said above, if you make too short trips like 50% of people, it will not have the time to start working and the catalytic converter will clog up with exhaust gases.
- Switching on the engine light: : Following a clogged catalytic converter, engine light of your Subaru Legacy may come on, do not think twice to consult our article to find out how to switch it off.
- A faulty lambda sensor : The catalyst works in close connection with the lambda sensors downstream and upstream of it, they will analyze the air flowing inside it, if it is clogged the sensors will often times as well have problems.
- A metallic noise coming from the exhaust: In the event that the catalyst is dead you should hear this noise which suggests that that the ceramic is damaged.
Why you should clean the catalytic converter of your Subaru Legacy
Before we accomplish with the step you are almost certainly most enthusiastic about, how to clean the catalytic converter of a Subaru Legacy? We will show you why it may be relevant for you to conduct this cleaning. In fact, a catalytic converter is a very expensive part (about 500 euros with the installation, the price can differ depending to the engines). In addition to being no longer good for passing the technical control , you may be at risk of over-consumption of fuel . Finally, the last interest is that cleaning a catalytic converter is not that expensive and doing it frequently will save you quite a lot of money.
How do you clean the catalytic converter from its Subaru Legacy?

- Scrubbing the catalytic converter from your Subaru Legacy on a regular basis: This strategy is especially practical for persons who mainly do short trips . To do this, nothing could be less difficult, from time to time, make a long trip (about 30 minutes to enhance the efficiency of the process), thinking of making your engine go up in revs so that the temperature in the catalyst increases and it can be cleaned.
- To use a catalyst cleaner: You can find some in a motor vehicle center for about 20 euros. All you have to do is add it to your fuel directly in your tank with about half a full tank. Afterwards you will have to drive on a long distance for at least 1 hour at mid-range by trying to go frequently at high rpm . If you can before and later on do an exhaust gas analysis to verify that you have recovered healthier exhaust fumes after the procedure. You can conduct this procedure every 15 000km.
