Purpose: Step-by-step instructions to help you install the EGR delete kit at home, boost engine performance, and reduce potential issues.
Important Pre-Installation Notice & Legal Disclaimer
- Before proceeding with the EGR delete, make sure to research and understand your local laws and regulations regarding emissions control modifications. Some areas prohibit removing or modifying emissions-related equipment, and non-compliance can lead to fines or other penalties.
- This kit and guide are intended for off-road and non-highway use only. Please keep all original parts if you need to restore the vehicle to its factory state.
Tools & Materials Needed
- A socket wrench set (including 8mm, 10mm, 14mm, and 15mm sockets)
- Deep socket
- Screwdrivers
- Allen wrenches
- Included gaskets and block-off plates
- Coolant
- Thread sealant or Teflon tape
Installation Overview
1. Preparation
- Check Parts:Before starting, compare the parts you received with the packing list to ensure everything is there.
- Disconnect Battery:For safety, disconnect the vehicle's battery to avoid any electrical issues during installation.
- Drain Coolant:Carefully open the coolant cap to relieve pressure in the system and prepare to remove EGR components.
2. Removing Initial Components
- Step 1:Remove the four 8mm bolts, oil dipstick, and plastic engine cover.
- Step 2:Take out the three 10mm bolts holding the oil dipstick bracket, then remove the dipstick carefully.
- Step 3:Loosen the clamps on the EGR pipe using a deep socket. Remove the 10mm bolt located in the middle of the pipe.
3. Removing Factory EGR Components
- Step 4:Detach the crossover pipe and reinstall the 10mm bolt to secure the assembly.
- Step 5:Unbolt the EGR valve by removing the four 10mm bolts, and disconnect the electrical connector from the valve.
- Step 6:Install the provided block-off plate using the supplied gaskets, ensuring a tight seal.
4. Removing & Replacing Coolant System Components
- Step 7:Remove the factory heat shields by unscrewing three 10mm nuts and two 8mm bolts.
- Step 8:Unbolt and remove the front EGR housing by removing four 10mm bolts.
- Step 9:Disconnect the factory breather vent line and coolant hoses. Expect a small loss of coolant—this is normal.
- Step 10:Carefully remove the EGR cooler, keeping it level to avoid coolant spills.
- Step 11:Remove the two 14mm bolts at the bottom of the EGR cooler, which may be hidden from view.
5. Installing Block-Off Plates & Modifying Coolant Connections
- Step 12:Use the factory 15mm nuts to install the front block-off plate.
- Step 13:Replace the factory high-mount coolant fitting with the supplied fitting. Use thread sealant or Teflon tape to prevent leaks.
6. Final Coolant Connections & System Assembly
- Step 14:Install the standpipe adapter using the provided bracket and secure it with the Allen bolt.
- Step 15:Reconnect the breather hose and attach the supplied hoses and clamps to the coolant ports. Make sure all connections are secure with no leaks.
- Step 16:Double-check that all components are firmly tightened, and there are no loose connections or leaks.
Post-Installation Check & Testing
- Coolant Check:After installation, refill the coolant reservoir to the recommended level. Run the engine briefly to circulate coolant, and top off as needed.
- Leak Check:Start the engine and look for any signs of coolant or exhaust leaks. Pay special attention to the block-off plates and hose connections.
- Test Drive:Take the truck for a short test drive to confirm everything is functioning as expected and that there are no error codes or unusual noises.
Troubleshooting & Common Issues
Issue 1: Minor Coolant Leak
Solution: Inspect all coolant connections, tighten any loose bolts, and check the gaskets for damage.
Issue 2: Check Engine Light or Fault Codes
Solution: Use a compatible tuning device to clear any fault codes and verify all electrical connections are secure.
Ongoing Maintenance Tips
- Periodically inspect the modified components, particularly the block-off plates and coolant connections, to ensure they remain secure.
- Keep your diagnostic tool handy to monitor for any fault codes that might arise during routine driving.
FAQs
Q1: Why should I not delete the EGR on my 6.7 Cummins?
A1: Deleting the EGR may violate emissions regulations in your area, leading to potential fines and legal consequences. It can also void the manufacturer’s warranty and limit your ability to pass emissions tests.
Q2: How much does it cost to fully delete a 6.7 Cummins?
A2: A full delete, including EGR, DPF, and tuning, can cost between $1,000 to $3,500 depending on the parts and tools you choose. Professional installation may add additional costs.
Q3: What are the main benefits of an EGR delete on a 6.7 Cummins?
A3: The benefits include improved engine performance, better fuel efficiency, reduced engine temperatures, and decreased carbon buildup in the intake manifold, potentially extending the engine's lifespan.
Q4: Will deleting the EGR cause any issues with my 6.7 Cummins?
A4: An EGR delete can trigger a check engine light if the ECU detects missing emissions components. Using a tuner to adjust the ECU is often necessary to avoid errors and optimize performance.
Q5: Is a tuner required for an EGR delete on a 6.7 Cummins?
A5: Yes, a tuner is usually required to recalibrate the ECU after deleting the EGR. This ensures the vehicle runs smoothly and prevents error codes related to the deleted components.
Q6: How much does a typical EGR delete kit installation take?
A6: DIY installation of an EGR delete kit can take around 3 to 5 hours, depending on your familiarity with the vehicle. A professional shop might complete it faster, usually within 2 to 3 hours.
Q7: Does a 2008 6.7 Cummins have a Diesel Particulate Filter (DPF)?
A7: Yes, the 2008 6.7 Cummins is equipped with a Diesel Particulate Filter (DPF) as part of its emissions system, along with an EGR and other emissions control devices.
Q8: Is deleting the EGR beneficial for off-road use only vehicles?
A8: Yes, for off-road use, an EGR delete can enhance performance and efficiency. However, it’s crucial to remember that this modification is generally not street-legal and should be used responsibly.
Q9: Will my truck’s fuel economy improve with an EGR delete?
A9: Yes, removing the EGR can lead to better fuel economy because it reduces the engine’s workload by stopping the recirculation of exhaust gases, resulting in more efficient combustion.
Q10: What should I do if I want to reverse the EGR delete?
A10: If you need to revert to stock, keep the original EGR components for reinstallation. You’ll also need to remove any aftermarket tuning software to restore the vehicle to its factory state.
