How to Install a 6.7 Cummins EGR Delete Kit
Installing a 6.7 Cummins EGR Delete Kit involves removing the soot-prone factory EGR cooler and valve assembly and replacing them with precision-machined block-off plates and high-temp coolant reroute components.
Installation Steps
- Vehicle Preparation: The truck is safely positioned and allowed to cool completely. Batteries are disconnected, and the engine coolant is drained, as the EGR cooler is a primary component of the vehicle's cooling system.
- Remove Factory EGR Components: The EGR valve, the large cooler assembly, and all connecting crossover tubes are unbolted. Careful attention is paid to disconnecting electrical sensors and vacuum lines to prevent damage to the factory wiring harness.
- Install Delete Components: Heavy-duty billet aluminum block-off plates are installed on the exhaust manifold and intake plenum. If the kit includes a throttle valve delete, it is swapped in at this stage using supplied gaskets to ensure a leak-proof seal.
- Coolant Reroute & Refill: A dedicated coolant bypass hose is installed to maintain proper circulation to the rear of the cylinder head, preventing localized hot spots. The cooling system is then refilled with the appropriate OAT or HOAT coolant and properly bled of air.
- Final Check & Software Sync: All hardware is inspected for torque and potential leaks. Before starting the engine, a compatible performance tuner must be used to reprogram the ECU, ensuring the truck recognizes the hardware changes and remains out of limp mode.
Note: Every EngineGo kit includes a comprehensive, model-specific guide to ensure your installation is seamless and your fitment is guaranteed.

FAQs
What is the difference between an EGR delete kit and a cooler delete kit?
An EGR delete kit may refer to a broader package that addresses the EGR system as a whole, while a cooler delete kit specifically focuses on removing or bypassing the factory EGR cooler. Some products combine both functions.
Can I still use my factory Exhaust Gas Temperature sensor?
Most EngineGo exhaust block-off plates come pre-tapped with a 1/8" NPT port. This allows you to easily reinstall your factory EGT probe or an aftermarket sensor to monitor your temperatures accurately after the delete.
Will this upgrade help reduce soot buildup?
Many off-road customers choose an EGR upgrade to help reduce the amount of hot, soot-laden exhaust reentering the intake. This may help support a cleaner intake tract over time.
