How to Clean your Genesis G80 EGR Valve: Role and Operation

Purpose of the EGR valve

The EGR valve of your car has been integrated to diesel engines mainly to lower pollution released by vehicles and to fulfill EURO specifications on Genesis G80 . It will as a consequence influence the quality of exhaust gas output and eliminate toxic particles, mainly Nitrogen Oxide.

Operation of the EGR valve

Before we learn how to clean the EGR valve on your Genesis G80 , we will take a look at how it operates. As seen before, its mission is to clean the exhaust fumes, so it will be installed at the engine outlet, thanks to a valve, it will be able to return the unburned exhaust gases to the engine for a second burn which will eliminate all unburned toxic particles. It will perform mainly at low speed because at high speed the combustion is enough to burn all these gases.

How to clean your Genesis G80 EGR valve: Identifying faults

The EGR valve, despite the fact very beneficial to limit the pollution emissions of your Genesis G80 , will regrettably tend to clog up because of soot/gas deposits that will build up in its system, which will inevitably risk obstructing the functions of the valve, until entirely blocking the engine motor, here are the symptoms that a faulty EGR valve on your Genesis G80 can bring about:

  • Motor light on
  • Performance loss
  • Technical assesment rejected
  • Black fumes
  • Car that grazes at low speed
  • Low RPM settings

How to clean your Genesis G80 EGR valve: In practice

And now we’ll start the part you are most excited about, how to clean the EGR valve of your car. Here are the two approaches that you can use.

Do it on your own

How to clean your Genesis G80 EGR valve system: Without dismantle

Although this procedure is less effective, it is however possible to consider a “rough” cleaning of your EGR valve, in fact, you will only need to use fuel additives, equivalent to the products used to clean the injection. These specific products must be injected into the running engine, at the right operating temperature, diluted in about 20 litres of fuel and run the engine for 3 or 4 minutes in high rev to clean the EGR valve of your Genesis G80.

How to clean your car EGR valve: With disassembly

Here is the most efficient procedure, which will require enough access to the EGR valve to accomplish the process on your own. If so, the procedure is fairly easy.

To make this happen, you will need to use a product such as solvent, petrol, oven cleaning product, which you will leave to act for ten minutes, then scrape off the rest using a scraper, finish cleaning with wire brush. If you want to go further, you can also clean the two conduits on which it is connected which may be scorched, for this, use a scraper and a vacuum cleaner to avoid dropping deposits in the conduits. You will only have to reassemble it and you will have finished cleaning the EGR valve of your Genesis G80.

Have it done by a professional

If, your EGR valve is not reachable because of the series or the engine of your car and if removing it would cause too many difficulties (removing too many auto parts that hinder access for example), how to clean the EGR valve of your Genesis G80? In cases like this, it would be better rather than launching yourself into an overly complex operation, you turn to an auto mechanic. He will be able to perform the job more cleanly and will be able, if necessary, to change the valve if it is dead. The cost of cleaning dependent on the difficulty of access is between 70 and 300 €.

Remove the EGR valve of your Genesis G80

Finally, some people make a more radical decision to limit the risk of a failed valve. Rather than cleaning the EGR valve of their Genesis G80, they simply prefer to block it in the closed position. This treatment will have the consequence of greatly increasing the pollution released by the car, of no longer complying with pollution standards, of having an engine warning light all day on and in the end risk fouling the engine. We highly recommend against making this choice. If you have other questions or want to learn more about your car, don’t be reluctant to take a look at our dedicated page.
