Pusher Install - 6.7L Dodge Cummins Heater Grid Delete

Introduction

This tutorial provides a step-by-step guide for installing the Pusher Heater Grid Delete on a 6.7L Dodge Cummins engine. This modification replaces the restrictive factory heater grid, improving airflow and enhancing overall engine performance. By following these steps, you can expect benefits such as a reduction in exhaust gas temperatures (EGTs), improved throttle response, and potentially better fuel economy.

Step 1: Gather Necessary Tools and Materials

Before starting the installation, ensure you have the following tools and materials:

• Pusher Heater Grid Delete kit
• OEM gaskets (included in the kit)
• Necessary hardware (included in the kit)
• Socket set
• Torque wrench
• Screwdriver set
• Shop rag or towel
• Safety glasses and gloves

Step 2: Prepare the Engine

1. Disconnect the Battery

   • Remove the negative terminal from the battery to prevent any electrical issues during installation.

2. Remove the Engine Cover

   • Use the appropriate tools to remove the engine cover, if applicable, to gain access to the heater grid.

3. Drain Coolant (if necessary)

   • If your installation requires removal of the heater grid that is connected to the cooling system, drain the coolant into a suitable container.

Step 3: Remove the Factory Heater Grid

1. Locate the Heater Grid

   • Identify the factory heater grid on the intake manifold.

2. Detach Wiring and Connections

   • Carefully disconnect any electrical connectors or hoses attached to the heater grid.

3. Unbolt the Heater Grid

   • Using a socket set, remove the bolts holding the factory heater grid in place. Keep these bolts as you may need them for installation.

4. Remove the Heater Grid

   • Gently lift the heater grid out of the intake manifold.

Step 4: Install the Pusher Heater Grid Delete

1. Clean the Surface

   • Use a shop rag to clean the mating surface of the intake manifold, ensuring it is free of debris and old gasket material.

2. Position the Heater Grid Delete

   • Place the Pusher Heater Grid Delete over the intake manifold, aligning it with the bolt holes.

3. Install the Gaskets

   • Place the OEM gaskets provided in the kit onto the specified areas to ensure a proper seal.

4. Secure the Grid Delete

   • Insert the bolts you removed earlier and tighten them in a crisscross pattern to ensure even pressure. Use a torque wrench to tighten to the manufacturer’s specifications.

Step 5: Reconnect Components

1. Reconnect Wiring and Hoses

   • Reattach any electrical connectors or hoses that were disconnected during the removal of the factory heater grid.

2. Replace the Engine Cover

   • If you removed the engine cover, reattach it securely.

Step 6: Reconnect the Battery and Test

1. Reconnect the Battery

   • Attach the negative terminal back to the battery.

2. Start the Engine

   • Turn on the engine and allow it to idle. Check for any leaks or unusual sounds.

3. Monitor Performance

   • Take the vehicle for a test drive to experience the improved throttle response and monitor EGTs.

Conclusion

By following these steps, you have successfully installed the Pusher Heater Grid Delete on your 6.7L Dodge Cummins engine.
