Step-by-Step Installation Process
Begin by disconnecting sensors and harnesses, then remove the EGR cooler and install the block-off plate. Modify the exhaust system, reroute coolant hoses, and reconnect components for testing.
Preparation
Before starting, ensure the engine is completely cool to avoid burns or injuries. Disconnect the battery to prevent accidental engine start. Gather all necessary tools and materials, including basic hand tools, specialized tools like an 8mm socket, and the EGR delete kit components. Drain the coolant system to prevent leaks during the process. Clear the workspace of any flammable materials and ensure good ventilation. Consult the specific EGR delete kit instructions for any unique preparation steps. Wear appropriate safety gear, including gloves and safety glasses. Double-check that all components are included in the kit before proceeding. Proper preparation is key to a smooth installation process.
Disconnecting Sensors and Harnesses
Begin by disconnecting the sensors and harnesses connected to the EGR system. Locate the EGR valve and cooler sensors, and gently unplug their electrical connectors. Use care to avoid damaging the wires or connectors. Next, disconnect the vacuum hose from the EGR valve by removing the 90-degree fitting. Plug the vacuum hose cap provided in the EGR delete kit to prevent vacuum leaks. Unplug any additional harnesses connected to the EGR cooler and reroute them away from the work area. Secure the disconnected harnesses to the PCM harness using zip ties to keep them organized. This step ensures safe removal of the EGR components without causing electrical issues.
Removing the EGR Cooler
Start by loosening the EGR cooler clamps using an 11mm deep socket or wrench. There are typically three clamps securing the cooler. Once loosened, carefully disconnect the coolant hoses from the backside of the cooler. Use a wrench to remove the bolts holding the EGR cooler in place, typically 6mm or 8mm bolts. Gently pull the cooler away from the engine, taking care not to damage surrounding components. If the cooler is stuck, wiggle it slightly to dislodge it without forcing. Remove the cooler completely and set it aside. This step is crucial for accessing the area where the block-off plate will be installed.
Installing the Block-Off Plate
After removing the EGR cooler, locate the exhaust manifold where the block-off plate will be installed. Ensure the area is clean and free of debris. Take the anodized block-off plate from the EGR delete kit and align it with the mounting holes on the manifold. Insert the supplied bolts through the plate and hand-tighten them to secure the plate in place. Use a torque wrench to tighten the bolts to the specified torque rating, usually around 15-20 ft-lbs. Ensure the plate is sealed properly to prevent leaks. Double-check the alignment and tightness to ensure a secure installation. This step is vital for maintaining proper engine function and preventing leaks.
Modifying the Exhaust System
With the EGR cooler removed, focus on modifying the exhaust system. Loosen the clamp securing the downpipe to the turbocharger using a 6mm socket. Remove the longer EGR pipe by taking out the five 6mm bolts. Disconnect the sensors and harnesses on top of the cooler, then unplug the vacuum hose. Install the supplied vacuum hose cap and secure the harnesses to the PCM harness using zip ties. Reroute the coolant hoses as needed to avoid interference. Ensure all connections are tight and properly routed to maintain exhaust flow and prevent leaks. This step ensures the exhaust system functions correctly without the EGR system.
Rerouting Coolant Hoses
Rerouting coolant hoses is crucial during an EGR delete to ensure proper cooling and prevent interference with the new setup. Start by loosening the clamp on the upper coolant hose using a 3/8″ wrench. Carefully disconnect the hose from the EGR cooler and set it aside. Next, reroute the lower coolant hose to avoid kinking or obstruction. Use the supplied coolant hose connector to secure the rerouted hose, ensuring a tight seal. Double-check all connections to prevent leaks. Properly rerouting the coolant hoses ensures your engine maintains optimal temperature control without relying on the EGR system. Consult your kit manual for precise routing instructions.
Reconnecting and Testing
After installing the EGR delete components, reconnect all sensors and harnesses securely. Ensure the coolant hoses are properly rerouted and connected to avoid leaks. Start the engine and monitor for any error codes or unusual performance. Check the exhaust system for leaks using a pressure test kit. Allow the engine to run under various loads to verify smooth operation. If everything functions correctly, the EGR delete is successful. Proper reconnection and thorough testing are essential to ensure reliability and performance gains. Always refer to your kit’s instructions for specific testing procedures to confirm the system is functioning as intended.
Post-Installation Considerations
After completing the EGR delete, inspect all connections for leaks and ensure proper functionality. Monitor engine performance and adjust tuning as needed for optimal operation.
Checking for Leaks
After installing the EGR delete kit, it’s crucial to thoroughly inspect for any leaks. Start by ensuring all connections, such as the block-off plate and exhaust system, are secure. Visually inspect coolant hoses, clamps, and gaskets for proper sealing. Turn on the engine and listen for any unusual sounds or hissing, which could indicate leaks. Use a pressure test kit if available to verify the integrity of the exhaust and coolant systems. Pay special attention to areas around the exhaust manifold and block-off plate, as these are common leak points. Addressing leaks promptly prevents damage and ensures optimal engine performance.
Tuning the Engine
Tuning the engine is essential after an EGR delete to optimize performance and ensure proper operation. Use a reputable tuner or engine calibration software to adjust settings, particularly for fuel injection and boost pressure. This prevents potential issues like excessive soot buildup or reduced power. The tune should account for the removal of the EGR system, ensuring the engine runs efficiently without it. It’s recommended to consult a professional if unfamiliar with tuning processes. Proper tuning enhances fuel efficiency, reduces emissions, and maximizes the benefits of the EGR delete, ensuring your Ford 6.7L Powerstroke operates at peak performance levels consistently.
Common Mistakes to Avoid
Incorrect bolt torque and improper harness connections are common errors during EGR delete installations. Ensure all components are securely fastened and connections are properly sealed to avoid leaks and damage.
Incorrect Bolt Torque
Using incorrect bolt torque during an EGR delete can lead to stripped threads, leaking gaskets, or damaged components. Always refer to the manufacturer’s torque specifications for bolts and fasteners. Over-tightening can warp surfaces, while under-tightening may result in leaks or loose connections. Ensure a torque wrench is used to apply the exact recommended torque values. This is especially critical for the block-off plate and exhaust manifold bolts. Double-check torque specs for each bolt type, as they may vary. Proper torque ensures a secure, leak-free installation and maintains the integrity of your engine and components.
Improper Harness Connections
Improper harness connections during an EGR delete can cause electrical issues, engine codes, or even system malfunctions. Always carefully unplug sensors and harnesses connected to the EGR cooler and valve. Use zip ties to secure loose wires to prevent damage or interference. Avoid pinching or stretching wires, as this can lead to open circuits. After installation, double-check all connections to ensure they are secure and properly routed. If unsure, consult the wiring diagram or seek professional assistance. Proper harness management ensures reliable communication between engine components and prevents potential electrical failures down the road. This step is crucial for maintaining your truck’s performance and avoiding costly repairs.
