How to Install a Cummins EGR Delete Kit
Installing a Cummins EGR Delete Kit involves removing the heavy, soot-clogged factory EGR cooler and valve assembly and replacing them with precision-machined block-off plates and high-flow bypass components.
Installation Steps
- Vehicle Preparation: Ensure the truck is parked on a level surface and the engine is completely cool to the touch. Disconnect both batteries to prevent electrical shorts. Because the Cummins EGR cooler is a "wet" system, the engine coolant must be partially drained to prevent spills during the removal of the cooler assembly.
- Remove Factory EGR Components: Disconnect the electrical connectors from the EGR valve and bypass actuator. Carefully unbolt the EGR cooler from the exhaust manifold and intake side. Remove the crossover tube and all associated mounting brackets. Use a shop vacuum or clean rags to ensure no debris enters the intake or exhaust ports during this process.
- Install Delete Components: Thoroughly clean the mounting surfaces on the exhaust and intake manifolds. Install the high-grade billet aluminum block-off plates using the provided high-temperature gaskets and stainless steel hardware. If your kit includes a coolant reroute hose, install it now to maintain proper coolant circulation across the back of the cylinder head.
- Reassemble & Refill Cooling System: Reinstall any intake piping or sensors that were moved for access. Refill the cooling system with fresh, manufacturer-approved OAT or HOAT coolant. It is vital to properly bleed the air from the cooling system using the bleeder screw located near the thermostat housing to prevent localized hot spots.
- Final Check & Software Calibration: Perform a visual inspection of all bolts, hose clamps, and electrical connections. Reconnect the batteries. Before starting the engine, you must use a "delete-capable" tuner to flash the ECU. This prevents the truck from entering Limp Mode or triggering Check Engine Lights. Once flashed, start the engine and inspect all sealing surfaces for exhaust or coolant leaks as the engine reaches operating temperature.

FAQ
What is a Cummins EGR Delete Kit?
A Cummins EGR Delete Kit is a performance modification that removes the factory Exhaust Gas Recirculation system. It replaces failure-prone components, like the EGR cooler and valve, with high-flow block-off plates and bypass hoses to prevent soot from re-entering your intake manifold.
Do I need a tuner after installing an EGR delete?
Yes. This is mandatory. Without delete-capable ECU tuning, your Cummins will immediately trigger a Check Engine Light and enter limp mode, which severely restricts engine power and speed.
Will an EGR delete improve my fuel economy?
Most Cummins owners report an increase of 1–3 MPG. This improvement occurs because the engine no longer has to process "dirty" air, and the turbocharger can operate more efficiently with reduced backpressure.
What is the difference between a Full Delete and Block-Off Plates?
A block-off kit only stops the flow of exhaust but leaves the heavy cooler in place. A full delete kit removes the entire cooler assembly, clearing clutter from your engine bay and permanently eliminating the risk of internal coolant leaks.
