EGR Cleaner

EGR valve cleaner is a type of spray fluid that helps clear debris and particles from the Exhaust Gas Recirculation system on an engine. When the EGR valve cleaner is used, it helps to prevent deposits from forming on this system, avoiding a number of problems such as decreased fuel economy and even possible engine failure. The valves are responsible for controlling the air and fuel mixture that is burned in the engine. Over time, debris can accumulate inside the valve, which can cause it to malfunction. By using an EGR valve cleaner, you can keep your engine running smoothly and avoid expensive repairs. Note: some EGR cleaner products are specific to petrol engines and others to diesel engines.

Every car has an emissions control system that helps to reduce the number of pollutants that are released into the atmosphere. One component of this system is the emissions control valve (EGR valve). Over time, the valves can become dirty and need to be cleaned. This can be done by using a specific cleaner or by simply blowing air through it.

EGR valve cleaner is a substance that helps clean the EGR valve on an engine. This cleaner is usually placed in a fuel injector and sprayed onto the EGR valve. When the cleaner enters the valve, it breaks down the dirt and oil that has built up on the valve. This helps to ensure that the valve functions properly and does not clog up with debris.

Symptoms of a failing EGR valve:

  • Rough idle
  • Poor performance
  • Increased fuel consumption
  • Fuel smell in car
  • Engine management light stays on
  • Knocking noises coming from the engine


Can you clean an EGR valve without removing it?

Yes, it is possible to clean an EGR valve without removing it. However, this will only work if the valve is not clogged. If the valve is clogged, it will need to be removed in order for the cleaner to be effective.

There are a few different ways to clean an EGR valve without removing it. One way is to use a cleaner that can be sprayed into the valve. Another way is to use a brush or plunger to clean the valve manually.

If the valve is clogged, it will need to be removed in order for the cleaner to be effective.

Where do you apply EGR cleaner?

EGR cleaners are used to clean the EGR valve and ports on a car. EGR cleaner is usually a spray or liquid that you can pour into the air intake. Be sure to read the directions carefully, as some cleaners should not be used on vehicles with direct injection engines.

Generally speaking, you should spray the product for two seconds into the air intake manifold but NOT into the intercooler. After each spray, wait until the idle rpm is restored and the engine runs stable. Repeat the process until the EGR is clean and the product is discharged.

Is it better to clean or replace the EGR valve?

There is no definitive answer when it comes to deciding whether to clean or replace an EGR valve. However, many experts agree that a good cleaning can often do the trick, especially if the valve is not too dirty or clogged. If the EGR valve is in bad shape, however, it may need to be replaced.

Why does my EGR valve keep getting clogged?

If your EGR keeps getting clogged repeatedly, it's probably a symptom of an underlying issue with the engine elsewhere.

The exhaust gas recirculation (EGR) valve helps reduce emissions by recirculating a small amount of exhaust gas back into the engine. This helps to lower the combustion temperature and prevent the formation of nitrogen oxides.

The EGR valve can get clogged over time with carbon deposits, which can hinder its ability to function properly. If your EGR valve is clogged, it can cause poor performance, decreased fuel economy, and increased emissions.

One way to help prevent the EGR valve from getting clogged is to use an EGR cleaner periodically. An EGR cleaner can help dissolve the carbon deposits that build up on the valve and keep it functioning properly.
