Why would you want to clean up the catalytic converter of your Mercury Mariner?

In this first section we will teach you why it may be valuable to clean the catalyst of your Mercury Mariner . Indeed for some of you it may seem obvious but most of you do not know how it works and the results dirty catalytic converter .

Role and functioning of the catalytic converter of a Mercury Mariner

.
The catalytic converter of your Mercury Mariner has the function to get rid of harmful exhaust gases related to the operation of your engine unit. Indeed, it is one of the most important components that fight against the pollution discharged by your Mercury Mariner. It will convert these harmful gases into water or non-polluting gases. In order to convert these gases, the catalyst of your Mercury Mariner 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 Mercury Mariner. If you are considering making adequately 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 optimize the life of this component and maintain ideal engine unit overall performance.

Consequences of a dirty or defective catalytic converter on Mercury Mariner

We will now discover what can be the results of a dirty or failing catalytic converter on Mercury Mariner . This will allow you to detect the signs of illness that should warn you to a breakdown of your catalytic converter, here is the list of symptoms of a defective catalytic converter:

  • Switching on the engine light: : Following a clogged catalytic converter, engine light of your Mercury Mariner may come on, do not think twice to consult our article 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 review the air flowing inside it, if it is clogged the sensors will more often than not as well have problems.
  • A metallic noise caused by the exhaust: In the event the catalyst is dead you should notice this noise which suggests that that the ceramic is damaged.

Why you should clean the catalytic converter of your Mercury Mariner

  • To use a catalyst cleaner: You can locate some in a motor vehicle center for about 20 euros. All you have to do is add it to your fuel straight 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 process. You can perform this process every 15 000km.
