The Heater Core will be located behind the dash. Hope that Helps.
To remove the heater core from a 1973 Ford F100, first disconnect the battery and drain the coolant from the radiator. Remove the dashboard and the heater box to access the heater core, which is typically secured with screws or clips. After disconnecting the heater hoses from the engine compartment, carefully pull out the heater core from the housing. Finally, reverse the process to install the new core, ensuring all connections are secure.
I replaced my heater core in 1991 for my ford F100 I6 300. If I remember correctly , it was a tiresome job because you have to remove the black plastic housing under the hood; which has a lot of small nuts. If my memory serves me, the heater core is under the hood, inside the black plastic compartment. The core is immediately under the place where your heater core hoses route to the firewall. You should have an easy time finding it. good luck

The book says 4 degrees BTDC for a F100
It's part of the heater controls, on the right hand side
It is attached to the headlight switch under the dash on the lefthand side
Under the frame of the truck not the oil pan or exhaust.
F100 1961-1966
