how to install egr delete kit 6.7 powerstroke

Installing an EGR (Exhaust Gas Recirculation) delete kit on a 6.7 Powerstroke diesel engine can help improve performance and reduce maintenance, but it’s important to note that EGR delete kits may not be legal for on-road use in some regions due to emissions regulations. Make sure to check local laws and regulations before proceeding. Here’s a general guide on how to install an EGR delete kit on a 6.7 Powerstroke:

Materials You’ll Need:

  • EGR delete kit (specific to your 6.7 Powerstroke model)
  • Basic hand tools (socket set, wrenches, pliers, etc.)
  • Replacement coolant and hose clamps (if necessary)
  • New gaskets and seals (included in the kit or purchased separately)
  • Safety goggles and gloves

Important Considerations:

  • Disconnect the vehicle’s battery before starting any work to ensure safety.
  • Consult your vehicle’s service manual for specific instructions and torque specifications.
  • Perform this modification at your own risk, as it may void warranties or violate emissions regulations in your area.


  1. Safety Precautions:
    • Put on safety goggles and gloves. Ensure the vehicle is parked on a level surface with the engine turned off, and the battery is disconnected.
  2. Locate and Access the EGR System:
    • The EGR components are typically located near the intake manifold and consist of the EGR valve, EGR cooler, and associated piping. Access these components by opening the vehicle’s hood.
  3. Identify the EGR Valve:
    • Locate the EGR valve in the EGR system. It’s usually a cylindrical or rectangular device with electrical connectors and hoses connected to it.
  4. Remove EGR Valve:
    • Use a socket or wrench to remove the bolts or nuts securing the EGR valve to the engine. Once removed, carefully disconnect the electrical connectors and hoses attached to the valve.
  5. Install Block-Off Plate or EGR Delete Pipe:
    • Depending on the kit you have, you’ll either install a block-off plate to cover the EGR valve opening on the intake manifold or replace the EGR valve with an EGR delete pipe. Follow the kit’s instructions for this step.
  6. Remove the EGR Cooler (if applicable):
    • If your kit includes removing the EGR cooler, disconnect the coolant hoses and remove the cooler from the vehicle. Install any provided block-off plates or plugs to seal the openings in the coolant system.
  7. Replace Gaskets and Seals:
    • If your kit includes new gaskets and seals, replace the old ones on the EGR system components, ensuring a proper seal.
  8. Reconnect Components:
    • Reconnect any electrical connectors and hoses that were disconnected earlier, securing them according to the kit’s instructions.
  9. Refill Coolant (if necessary):
    • If you removed the EGR cooler and coolant hoses, refill the cooling system with fresh coolant as per the vehicle’s service manual.
  10. Battery Reconnection:
    • Reconnect the vehicle’s battery.
  11. Start the Engine:
    • Start the engine and check for any leaks, unusual noises, or warning lights on the dashboard. Monitor the vehicle’s performance to ensure it runs smoothly.
  12. Clear Error Codes (if necessary):
    • If any error codes or warning lights appear on the dashboard, you may need to use an OBD-II scanner to clear them.
  13. Test Drive:
    • Take the vehicle for a test drive to ensure everything is functioning properly. Monitor engine performance and exhaust emissions.

Please note that EGR delete kits are intended for off-road or racing use only in many areas due to emissions regulations. Removing the EGR system may also affect the vehicle’s warranty. Always consult with a qualified mechanic or shop that specializes in diesel engines to ensure the work is performed correctly and that your vehicle complies with local regulations.
