Vehicles equipped with gasoline or diesel engines are very polluting. Indeed, nitrogen dioxide emissions are harmful to humans and the planet. Faced with this, the installation of an EGR valve has become compulsory in France, as well as throughout Europe. This comes from the strong desire of different countries to comply with anti-pollution standards. This EGR valve allows these emissions to be reduced by reusing the exhaust gas. and, this allows complete exploitation of the fuel. However, you should know that it presents a major disadvantage for the vehicle and its user: it causes a fairly significant production of soot. And, this has a direct consequence on the valve itself. Since it obstructs it. Which subsequently causes heavy clogging of the injection system. In this article you can learn how to clean an Opel Corsa EGR valve.
The role of an Opel Corsa EGR valve
For several years, the diesel engines inserted in Opel Corsa cars all have an EGR valve. The latter has the role of reduction of pollution produced by its vehicles. To do this, the exhaust gases are controlled to obtain better quality. Add to this that the majority of toxic particles are eliminated.
How does an Opel Corsa EGR valve work?
Cleaning an Opel Corsa EGR valve cannot be done without a complete understanding of its mode of operation. Indeed, having as its main mission the exhaust gas management, the valve is therefore placed at the level of the engine. And more precisely upon its release. The transfer of these gases to the engine is possible thanks to the availability ofa flap. This is how the exhaust gas is burned a second time to remove all traces of toxic particles.
The use of the Opel Corsa EGR valve is mainly effective in cases of low revs. Because it is at this moment that the combustion is not strong. And, that the gases are only partially destroyed.
Detecting a fault in the Opel Corsa EGR valve
Pollution emissions are mainly prevented by the availability of an Opel Corsa EGR valve. However, it has the disadvantage of repetitive obstruction. This is due to soot deposition at the level of the valve mechanism. And, over time, the latter will show malfunctions which will subsequently cause a blockage in the operation of its engine.
You should know that an Opel Corsa EGR valve shows various symptoms which can warn you of its malfunction. First of all, the first symptom will be thelighting of a light. Then this will cause a power drop. And sometimes the appearance of black smoke. Add to this, that several other symptoms can also be revealing, such as:
- Refusal of a technical inspection
- The wedging
- Vehicles at low speed that graze
Clean the EGR valve Opel Corsa
It is possible to clean the Opel Corsa EGR valve yourself. To do this, you can do it without dismantling it. To achieve this, you will need a cleaning product whose components are mainly fuel additives. The latter must then be administered within the engine. The latter must have an adequate temperature. In order to reach it, you will have to do it when it is running. You should know that the product must be diluted in at least 20 L of fuel.
But you should know that this process is not very effective. Indeed, for a thorough cleaning, it is preferable to dismantle the EGR valve of your Opel Corsa. To do this, first start with the location of its electromagnet to be able to unscrew and disconnect it. Then, after removing the EGR valve from the vehicle, you can proceed to clean it using a solvent product which should be left for at least 10 minutes. For the rest of the dirt, you will have to remove it with a scraper. Finally, the last step will be the passage of a metal brush to get rid of the last residues.
For a more thorough cleaning, it is possible to scrape and then vacuum at the level of the ducts. Here are our 10 Tips to Clean Your Car Like a Pro.
Furthermore, if you have no knowledge of mechanics at all, it is best to entrust this task to an expert. Add to this that in certain Opel Corsa models, the EGR valve is difficult to access. And, requires significant equipment to extricate yourself. It should preferably be taken to a mechanic. This will guarantee you a best work. However, this alternative has the disadvantage of price. The latter varies depending on the level of difficulty of accessing the valve. It can range from 60 to 300 euros.
You should know that many motorists opt for the removal of their EGR valve in their Opel Corsa car. To do this, the latter is locked. This will certainly allowavoid breakdowns. But, the vehicle is very polluting. As a result, it does not meet European standards regarding pollution.
