The exhaust gas recirculation (EGR) valve on a 6.6 Duramax diesel engine is a emissions control device that recirculates a portion of the exhaust gas back into the intake manifold. This helps to cool the intake charge and reduce the formation of NOx emissions. However, the EGR valve can also become clogged with soot and other deposits, which can lead to a loss of power and performance. Deleting the EGR valve is a popular modification for 6.6 Duramax engines, as it can help to improve performance and fuel economy.

Tools and Materials Needed

The following tools and materials are needed to delete the EGR valve on a 6.6 Duramax engine:

• EGR delete kit
• Wrenches
• Socket set
• Screwdriver
• Penetrating oil
• Rags

Steps in the Process

The following steps are involved in deleting the EGR valve on a 6.6 Duramax engine:

1. Locate the EGR valve. The EGR valve is located on the passenger side of the engine, near the intake manifold.
2. Disconnect the electrical connector from the EGR valve. Use a screwdriver to disconnect the electrical connector from the EGR valve.
3. Remove the EGR valve bolts. Use a wrench to remove the bolts that hold the EGR valve in place.
4. Remove the EGR valve. Carefully remove the EGR valve from the engine.
5. Install the EGR delete kit. Follow the instructions included with the EGR delete kit to install the kit.
6. Reinstall the EGR valve bolts. Use a wrench to reinstall the bolts that hold the EGR valve in place.
7. Reconnect the electrical connector to the EGR valve. Use a screwdriver to reconnect the electrical connector to the EGR valve.

Deleting the EGR valve on a 6.6 Duramax engine is a relatively simple procedure that can be completed in about an hour. However, it is important to note that deleting the EGR valve will void your vehicle’s warranty. If you are unsure about whether or not you should delete the EGR valve, it is best to consult with a qualified diesel mechanic.

3. Remove the EGR valve

The EGR valve is located on the intake manifold, near the throttle body. To remove it, you will need to:

1. Remove the air intake tube.
2. Disconnect the electrical connector from the EGR valve.
3. Remove the two bolts that hold the EGR valve in place.
4. Carefully remove the EGR valve from the intake manifold.

4. Remove the EGR cooler

The EGR cooler is located on the back of the engine, near the turbocharger. To remove it, you will need to:

1. Remove the air intake tube.
2. Disconnect the electrical connector from the EGR cooler.
3. Remove the two bolts that hold the EGR cooler in place.
4. Carefully remove the EGR cooler from the engine.

Once you have removed the EGR valve and EGR cooler, you can reinstall the air intake tube and reconnect the electrical connectors. You will then need to reprogram the truck’s computer to delete the EGR codes. This can be done by using a scan tool or by taking the truck to a qualified diesel mechanic.

Here are some additional tips for deleting the EGR on a 6.6 Duramax:

• Make sure to disconnect the battery before starting any work on the truck.
• Be careful not to damage any of the components during removal.
• If you are not comfortable working on your truck, take it to a qualified diesel mechanic.

Deleting the EGR on a 6.6 Duramax can improve performance and fuel economy. It can also help to prevent EGR-related problems, such as EGR cooler failure and EGR valve clogging.

How To Delete Egr On 6.6 Duramax?

Q: What is the EGR valve and why do I need to delete it?

A: The EGR valve (Exhaust Gas Recirculation) is a emissions control device that recirculates exhaust gas back into the engine. This helps to reduce NOx emissions, but it can also cause problems such as EGR cooler clogging, EGR valve failure, and poor fuel economy. Deleting the EGR valve can help to improve performance and reliability, but it may also increase emissions.
