A catalytic converter is an important part of contemporary cars, as it purifies your vehicle’s exhaust gases and thus suits modern pollution standards. However, it is possible that it may turned out to be clogged or malfunction, in which case a change or cleaning is important. Today we are going to look at how to clean a catalytic converter on Subaru Crosstrek? To do this, to begin with, we will describe the scenarios in which it may be interesting to clean the catalytic converter of your Subaru Crosstrek, then, how to conduct this cleaning to recover the overall performance of the catalytic converter of your car.

Why would you want to clean up the catalytic converter of your Subaru Crosstrek?

In this first part we will describe why it may be significant to clean the catalyst of your Subaru Crosstrek . In fact for some of you it may seem obvious but most of you do not understand how it works and the outcomes dirty catalytic converter .

Function and functioning of the catalytic converter of a Subaru Crosstrek

.
The catalytic converter of your Subaru Crosstrek has the objective to eliminate harmful exhaust gases related to the process of your engine. In fact, it is one of the main elements that fight against the pollution discharged by your Subaru Crosstrek. It will convert these harmful gases into water or non-polluting gases. In order to convert these gases, the catalyst of your Subaru Crosstrek 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 therefore necessary to avoid clogging the catalytic converter of your Subaru Crosstrek. If you are thinking of making sufficiently long journeys to heat it up frequently (count more than 10 kilometres for the catalyst to reach the right temperature), this will allow you to optimise the life of this part and preserve best engine performance.

Outcomes of a dirty or defective catalytic converter on Subaru Crosstrek

We will now discover what can be the outcomes of a dirty or failing catalytic converter on Subaru Crosstrek . This will allow you to identify the signs of illness that should notify you to a breakdown of your catalytic converter, here is the list of signs of illness of a defective catalytic converter:

  • The catalytic converter of your Subaru Crosstrek is blocked: As we said above, if you make too short journeys like 50% of people, it will not have the time to start functioning 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 Crosstrek may come on, do not think twice to seek advice from our content page to find out how to switch it off.
  • A defective 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 quite often also have problems.
  • A metallic noise caused by the exhaust: In the event the catalyst is dead you should hear this noise which means that the ceramic is damaged.

Why you should clean the catalytic converter of your Subaru Crosstrek

Before we accomplish with the step you are likely most keen on, how to clean the catalytic converter of a Subaru Crosstrek? We will describe why it may be relevant for you to execute this cleaning. In fact, a catalytic converter is a very expensive part (about 500 euros with the set up, the price can fluctuate 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 Crosstrek?

Finally here is the stage that you are most certainly most keen on in this article content, how to clean the catalytic converter of your Subaru Crosstrek? Know that this process is very simple, and that there are two approaches to do it:

  • Scrubbing the catalytic converter from your Subaru Crosstrek regularly: This approach is specifically useful for persons who principally do short trips . To do so, 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 locate some in a car 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 check that you have recovered healthier exhaust fumes after the procedure. You can execute this procedure every 15 000km.
