How to Use Wynns EGR Cleaner

Keeping your vehicle’s engine running smoothly and efficiently is crucial for optimal performance, fuel economy, and reduced emissions. The EGR (Exhaust Gas Recirculation) system plays a vital role in this process, helping to reduce nitrogen oxide emissions by recirculating a portion of the exhaust gas back into the engine. Over time, the EGR system can become clogged with carbon deposits, leading to engine issues and decreased efficiency. Fortunately, Wynns offers a reliable EGR cleaner that can help address this problem.

What is Wynns EGR Cleaner?

Wynns EGR Cleaner is a specially formulated solution designed to effectively remove carbon deposits from the EGR system, including the EGR valve and other components. By using Wynns EGR Cleaner, you can restore the proper functioning of the EGR system and improve your vehicle’s overall performance.

Step-by-Step Guide on Using Wynns EGR Cleaner

Here’s a simple and easy-to-follow guide on how to use Wynns EGR Cleaner to tackle carbon buildup in your vehicle’s EGR system:

Step 1: Park in a well-ventilated area

Before beginning the EGR cleaning process, make sure you park your vehicle in a well-ventilated area. This will help minimize exposure to any fumes that may be emitted during the cleaning process.

Step 2: Locate the EGR valve

The next step is to locate the EGR valve. In most vehicles, the EGR valve can be found near the intake manifold or on the engine’s side. Refer to your vehicle’s user manual if you are unsure about its exact location.

Step 3: Prepare the engine

Ensure that the engine is turned off, the key is removed from the ignition, and all electrical components are switched off. This will prevent any accidental starting of the engine or interference with the cleaning process.

Step 4: Remove the EGR valve

Once the engine is ready, carefully remove the EGR valve from its mounting. Be cautious when handling the valve so as not to damage any surrounding components.

Step 5: Spray the EGR valve with Wynns EGR Cleaner

With the EGR valve removed, hold it in a secure position and spray Wynns EGR Cleaner directly onto the valve, making sure to cover all areas affected by carbon deposits. Allow the cleaner to penetrate the deposits for a few minutes, ensuring maximum effectiveness.

Step 6: Clean the EGR valve

Using a soft brush, gently scrub the EGR valve to help loosen the carbon buildup. Be careful not to use excessive force, as this may cause damage. Continue scrubbing until the valve appears clean and free from any visible deposits.

Step 7: Reinstall the EGR valve

Once the EGR valve is clean, carefully place it back into its original mounting position. Ensure that it is securely attached and properly aligned with any gaskets or seals.

Step 8: Start the engine

Now it’s time to start the engine and allow it to run for a few minutes. This will help burn off any remaining cleaner and dislodged carbon deposits from the EGR system. You may notice some smoke or fumes during this process, but they should dissipate quickly.

Step 9: Test the EGR system

With the engine running, observe the vehicle’s performance and listen for any unusual noises or vibrations. If everything appears normal, it indicates that the EGR system is functioning properly again.

Step 10: Repeat if necessary

If you still notice performance issues or suspect there may be lingering carbon buildup, you can repeat the cleaning process with Wynns EGR Cleaner. It’s always best to consult your vehicle’s user manual and follow the manufacturer’s recommendations.


Regular maintenance and cleaning of your vehicle’s EGR system are vital for optimal engine performance and reduced emissions. Utilizing Wynns EGR Cleaner can help remove carbon deposits from the EGR valve and other components, restoring their proper functionality. By following this step-by-step guide, you can easily use Wynns EGR Cleaner to improve your vehicle’s overall performance and keep the engine running smoothly.
