How to Install a 6.7L Powerstroke EGR Delete Kit - Complete Guide

Learn how to install a 6.7L Powerstroke EGR delete kit with our comprehensive guide. Discover the benefits, required tools, step-by-step instructions, and answers to common questions. Optimize your truck's performance with our expert tips and recommendations.

1. Introduction

Overview of EGR Delete

The Exhaust Gas Recirculation (EGR) system helps reduce nitrogen oxide emissions by recirculating a portion of the exhaust gas back into the engine's intake. While this is beneficial for emission control, it can also lead to a buildup of soot and other contaminants, which may reduce engine performance over time.

Performing an EGR delete on a 6.7L Powerstroke engine can help enhance its performance. By removing the EGR system, you can improve airflow, increase horsepower, and potentially improve fuel efficiency. However, it's important to note that this modification is intended for off-road and race use only. Legal considerations must be taken into account, as EGR delete kit are not compliant with emission regulations for on-road vehicles.

3. Preparation

Pre-Installation Steps

Before you start the EGR delete process on your 6.7L Powerstroke, it's crucial to take some initial steps to ensure your safety and prepare the vehicle properly.

Safety Precautions:

  • Wear gloves and safety glasses to protect yourself from potential hazards.
  • Ensure the vehicle is on a level surface and engage the parking brake.

Disconnecting the Negative Battery Terminals:

  • This step is essential to prevent any electrical short circuits or accidental startups.
  • Locate the negative terminals on both batteries and disconnect them using the appropriate wrench.

Raising the Truck:

  • Use ramps or a hydraulic jack to elevate the front of the truck.
  • Position drain pails beneath the radiators to catch the coolant that will be drained.

With these steps completed, your vehicle is now ready for the EGR delete process. These preparations will ensure a smooth and safe procedure.

Ready to move forward? Let’s begin with draining the coolant and removing stock components in the next section.

4. Draining Coolant and Removing Stock Components

Draining the Coolant

Draining the coolant is the first step in the EGR delete process for your 6.7L Powerstroke. Properly draining the coolant ensures that you can work on the engine without any spillage or mess.

Locate the Drain Plugs:

  • The 6.7L Powerstroke has two radiators, each with its own drain plug.
  • Position your drain pails beneath each radiator.

Open the Drain Plugs:

  • Use pliers or small vice grips to turn the drain plugs. They rotate about 180 degrees and then pull out as you twist them.
  • Be gentle, as these plugs are plastic and can break easily.

Remove the Caps:

To allow more airflow and speed up the draining process, remove the caps from the coolant reservoir and the radiators.

Draining the coolant completely is crucial to avoid any spillage when you start working on the EGR system. Make sure the drain plugs are securely opened and the coolant flows freely into the pails.

Removing the Air Intake System

Next, you’ll need to remove the air intake system to gain access to the EGR components.

Unbolt the Air Intake Box:

  • Use an 8mm socket to remove the two bolts securing the air intake box.
  • Disconnect the mass airflow sensor by unplugging it carefully.

Remove the Intake Pipe:

  • Loosen the clamp holding the intake pipe using a 7mm or 8mm socket.
  • Gently pull the intake pipe off the throttle body.

Clear the Area:

  • Your truck might have additional hoses or components connected to the air intake system. Remove these as necessary.
  • Set aside the air intake box and pipe in a safe place.

By removing the air intake system, you create more space to work on the EGR components. This step is vital for a smooth and hassle-free EGR delete process.

5. EGR Removal Process

Accessing the EGR System

With the air intake system removed, you can now access the EGR components. This step involves clearing additional space and preparing the area for EGR removal.

Remove Coolant Lines:

  • Identify the coolant lines connected to the EGR cooler.
  • Use pliers to remove the clamps and carefully pry off the coolant lines. Set them aside.

Disconnect Wiring Harnesses and Sensors:

  • Locate the wiring harnesses and sensors attached to the EGR system.
  • Unplug any sensors and disconnect the wiring harnesses to free up space.
  • If necessary, remove bolts holding the harness tray in place to gain better access.

Unbolt Brackets and Heat Shields:

  • Remove any brackets or heat shields obstructing the EGR cooler.
  • Use the appropriate tools to unbolt these components and set them aside.

By clearing the area around the EGR system, you’ll have easier access to the EGR cooler and related components. This preparation is crucial for the smooth removal of the EGR system.

Removing the EGR Cooler

Now, you’re ready to remove the EGR cooler. This step requires careful handling to avoid damaging other engine components.

Unbolt the EGR Cooler:

  • Identify the bolts securing the EGR cooler. Typically, there are six bolts in total: three on each side.
  • Use the appropriate socket to remove these bolts. Be cautious as some bolts might be difficult to reach.

Handle Stubborn Bolts:

  • If you encounter stubborn bolts, apply penetrating fluid and allow it to sit for a few minutes.
  • Use a Sawzall if necessary to cut any obstructing brackets. Ensure you don’t damage surrounding components.

Remove the EGR Cooler:

  • Once all bolts are removed, gently wiggle the EGR cooler to break it free from the dowels holding it in place.
  • Carefully pull the EGR cooler forward and out of the engine bay. Be mindful of the injector wiring harness and other delicate components.

Successfully removing the EGR cooler is a significant milestone in the EGR delete process. This step paves the way for installing the new components.

6. Installing the EGR Delete Kit

Installing the Blocker Plates

Now that the EGR cooler is removed, it’s time to install the blocker plates. These plates are essential for sealing off the ports where the EGR components were removed.

Prepare the Blocker Plates:

  • Lay out the blocker plates included in your SPELAB EGR Delete Kit.
  • Ensure you have the factory gaskets ready to reuse for proper sealing.

Install the Blocker Plates:

Position the first blocker plate where the EGR cooler was removed.

Reuse the factory gasket and secure the plate with the provided bolts. Ensure the bolts are threaded all the way to avoid any leaks.

Repeat the process for the second blocker plate on the exhaust side. Again, ensure the gasket is properly seated and the bolts are securely tightened.

Check for Proper Fit:

Double-check that both blocker plates are correctly installed and there are no gaps or misalignments.

Tighten all bolts to the specified torque to ensure a secure fit and prevent any leaks.

Installing the blocker plates is a critical step in the EGR delete process. Proper installation ensures that your engine runs smoothly without any leaks or performance issues.

Reassembly and Final Checks

With the blocker plates installed, it’s time to reassemble the engine components and perform final checks.

Reinstall the Air Intake System:

Reattach the air intake pipe and secure it with the clamp.

Reinstall the air intake box and reconnect the mass airflow sensor.

Reconnect Electrical Components:

Reconnect all wiring harnesses and sensors that were unplugged earlier.

Ensure that each connection is secure and properly seated.

Add Coolant:

Refill the coolant reservoir and radiators with the appropriate type and amount of coolant.

Replace the caps on the coolant reservoir and radiators.

Reconnect Battery Terminals:

Reconnect the negative battery terminals to restore power to the vehicle.

Perform Final Checks:

  • Double-check all connections, clamps, and bolts to ensure everything is secure.
  • Look for any signs of leaks or loose components.

By carefully reassembling the engine components and performing final checks, you can ensure that your 6.7L Powerstroke is ready for testing and troubleshooting.
