Removing the Glove Box and Underdash Panel
Remove Glove Box
The first step in replacing the heater core in a 1997 Ford F150 is to remove the glove box. This may sound like a daunting task, but it is actually quite simple. Start by opening the glove box and emptying its contents. Then, locate the screws or clips that are holding the glove box in place.
These may be located on the sides or underneath the glove box. Use a screwdriver or a socket wrench to remove these screws or clips. Once they are removed, gently pull the glove box out of the dashboard. Be careful not to damage any of the wiring or components behind it.
Remove Underdash Panel and Disconnect Wiring
After removing the glove box, the next step is to remove the underdash panel. This panel is located beneath the glove box and provides access to the heater core. Look for any screws or clips holding the panel in place and remove them using a screwdriver or socket wrench.
Once the screws or clips are removed, carefully pull the panel away from the dashboard. Take note of any wiring or cables that are connected to the panel. These will need to be disconnected before the panel can be fully removed.
To disconnect the wiring, locate the connectors that are attached to the underdash panel. These connectors may be secured with clips or screws. Carefully remove these connectors, being mindful not to damage any of the wiring or connectors.
It may be helpful to take pictures or make notes of the connections to ensure they can be reconnected correctly later on.
Once the wiring is disconnected, gently pull the underdash panel away from the dashboard. Set it aside in a safe place, making sure not to misplace any screws or clips that were removed. With the glove box and underdash panel removed, you will now have clear access to the heater core and can proceed with the next steps of the replacement process.
Accessing the Heater Core
Replacing the heater core in a 1997 Ford F150 may seem like a daunting task, but with the right steps, it can be completed successfully. The first step in accessing the heater core is to remove the firewall plate.
Remove Firewall Plate
The firewall plate is located on the passenger side of the vehicle, near the back of the engine compartment. To remove it, begin by disconnecting the negative battery cable to ensure safety. Then, remove the screws or bolts that hold the plate in place.
Carefully detach any electrical connections that may be attached to the plate, and set it aside.
Remove Support Bracket
Once the firewall plate is removed, the next step is to remove the support bracket. This bracket is typically located near the firewall plate and is used to secure the heater core housing. Use a wrench or socket set to loosen and remove the bolts or screws that hold the support bracket in place.
Once removed, set the support bracket aside.
Remove Heater Core Housing
With the firewall plate and support bracket out of the way, it’s time to remove the heater core housing. The housing is usually located on the passenger side of the vehicle, near the firewall. Carefully detach any hoses or connections that are attached to the housing, making sure to catch any coolant that may spill out.
Once the hoses are disconnected, remove the bolts or screws that secure the housing in place. Finally, carefully remove the housing, taking care not to damage the heater core.
By following these steps, you can effectively access the heater core in a 1997 Ford F150. Remember to consult the vehicle’s manual for specific instructions and safety precautions.

Removing and Replacing the Heater Core
Replacing the heater core in a 1997 Ford F150 can be a daunting task, but with the right tools and a step-by-step guide, it can be done successfully. Here is a detailed breakdown of how to remove and replace the heater core in your truck.
Drain Coolant
The first step in replacing the heater core is to drain the coolant from the radiator. This can be done by locating the drain plug at the bottom of the radiator and opening it with a wrench. Make sure to have a container ready to catch the coolant as it drains out.
Once the coolant is drained, be sure to dispose of it properly.
Disconnect Heater Hoses
After the coolant has been drained, the next step is to disconnect the heater hoses from the heater core. These hoses are usually located on the passenger side of the engine compartment and can be removed by loosening the hose clamps with a screwdriver or pliers.
It is important to pay attention to which hose goes where to ensure proper reinstallation later.
Remove and Install New Heater Core
Once the heater hoses are disconnected, the next step is to remove the old heater core. This can usually be done by removing a few screws or bolts that hold the heater core in place. Carefully remove the old heater core, being mindful not to damage any surrounding components.
After removing the old heater core, it is time to install the new one. Start by placing the new heater core in the same position as the old one and secure it with the screws or bolts. Once the new heater core is securely in place, reattach the heater hoses, making sure to tighten the hose clamps properly.
Finally, refill the radiator with fresh coolant and start the engine to check for any leaks. If everything looks good, you have successfully replaced the heater core in your 1997 Ford F150!

Reassembly and Refilling Coolant
Replace All Removed Components
Now that you have successfully replaced the heater core in your 1997 Ford F150, it’s time to start the reassembly process. Begin by carefully reinstalling all the components that you removed during the disassembly phase.
Make sure to follow the steps in reverse order and refer to any notes or photographs you took along the way for guidance.
Double-check that all wiring harnesses, hoses, and connectors are properly reattached. Take your time and ensure that everything is secured tightly and in the correct position. This will help prevent any potential issues or leaks once you start the vehicle.
If you encounter any difficulties during the reassembly process, consult the vehicle’s repair manual or seek assistance from a qualified mechanic. It’s important to complete this step thoroughly to ensure the heater core functions properly and the vehicle operates safely.
Refill Coolant System
Once you have replaced all the removed components, it’s time to refill the coolant system. Start by locating the coolant reservoir or radiator cap, depending on your vehicle model. Carefully remove the cap and set it aside.
Next, check the owner’s manual or consult the vehicle’s repair manual to determine the proper type and amount of coolant to use. It’s crucial to use the correct coolant to prevent any damage to the engine or cooling system.
If necessary, mix the coolant with distilled water according to the manufacturer’s instructions.
Slowly pour the coolant mixture into the coolant reservoir or radiator opening. Be cautious not to overfill, as this can cause coolant to overflow and potentially damage the engine. Use a funnel if needed to prevent spills.
After filling the coolant system, replace the cap securely. Start the vehicle and let it run for a few minutes to circulate the coolant throughout the system. Monitor the coolant level and top it up if necessary, ensuring it stays within the recommended range.
Remember to dispose of any old coolant and containers properly, following local regulations and guidelines. It’s important to handle coolant responsibly, as it can be toxic and harmful to the environment.
Congratulations! You have successfully reassembled your 1997 Ford F150’s heater core and refilled the coolant system. Your vehicle should now be ready to provide you with warm and comfortable rides even in the coldest weather.
