• Exhaust manifold block-off plate
• Coolant line block-off fittings
• EGR valve delete kit
• Aluminum alloy or rubber components for durability
• High-temperature gaskets and seals
• Fittings for coolant and vacuum hoses

Ensure all materials are compatible with your Ford 6․7L Powerstroke engine․

Preparation for the EGR Delete

Gather all tools and materials, review instructions, and ensure proper safety measures․ Disconnect the battery and prepare the cooling system for modification․ Clean the engine bay for better access․

5․1 Pre-Installation Checklist

• Disconnect the battery to ensure safety during the process․
• Remove the intake pipe and air filter housing for better access․
• Spray penetrating fluid on EGR cooler bolts to loosen them․
• Gather all tools and materials, including the EGR delete kit․
• Clean the engine bay to prevent debris interference․
• Check for any leaks in the cooling system before modifications․

5․2 Cooling System Preparation

Before proceeding, drain the coolant system to prevent spills during disassembly․ Inspect all hoses and connections for leaks or damage․ Once the EGR cooler is removed, reroute the coolant lines to bypass the deleted system․ After installation, refill the coolant with a 50/50 mix of antifreeze and water․ Bleed the system to remove air pockets and ensure proper circulation․ torque all connections to specifications․

Step-by-Step Installation Instructions

Remove the EGR cooler by loosening bolts with an 8mm socket․ Unplug harnesses and hoses, then install block-off plates․ Bypass the EGR system using the provided kit․ Ensure all connections are secure and leak-free․ Follow the kit instructions carefully for a successful installation․

6․1 Removing the EGR Cooler

Identify the bolts securing the EGR cooler, typically six in total․ Use an 8mm socket to loosen and remove them․ Gently wiggle the cooler to break it free from dowels; Unplug harnesses and hoses, including the 90-degree fitting․ Carefully pull the cooler forward and out of the engine bay․ Spray penetrating fluid if bolts are stubborn․ Work patiently to avoid damage or breaking components․

6․2 Installing the Block Off Plates

After removing the EGR cooler, install the block off plates using the supplied factory gasket․ Ensure proper alignment and secure them with the provided bolts․ Tighten in a star pattern to avoid warping․ Reconnect any coolant lines or hoses, ensuring a leak-free seal․ Use penetrating fluid if needed for stubborn bolts․ Refer to your kit’s torque specifications for proper tightening․ This step ensures a clean and secure installation․

6․3 Bypassing the EGR System

Disconnect the EGR valve electrical connector and vacuum hose․ Re-route the coolant lines removed from the EGR cooler to their respective ports․ Ensure all connections are secure and leak-free․ Use the block-off plates to seal the exhaust manifold ports․ Tighten all bolts to the specified torque․ Double-check for any remaining hoses or wires that may need rerouting․ Test the system for proper operation․

Post-Installation Steps

After completing the EGR delete, start the engine and check for leaks․ Monitor performance and ensure proper functionality․ Address any issues promptly to maintain reliability and efficiency․

7․1 Testing the Engine After EGR Delete

After completing the EGR delete, start the engine and check for leaks․ Monitor the dashboard for error codes and ensure proper functionality․ Take a test drive to assess performance improvements and verify the absence of issues․ This step ensures the delete was successful and maintains engine reliability and efficiency․

7․2 Tuning the Engine for Optimal Performance

After the EGR delete, consult a tuner or use a tuner tool to optimize engine performance․ Adjust settings to maximize horsepower, torque, and fuel efficiency․ Ensure the engine computer is recalibrated to account for the removed EGR system․ Monitor engine parameters and performance during the tuning process to achieve the best results․ Proper tuning ensures the EGR delete enhances your truck’s overall performance and reliability․
