The heater core on a 1999 Ford F250 Superduty is replaced by removing the heater hoses, disconnecting the wiring harness, and removing the retaining bolts. The cover can then be removed, the heater core unbolted, and removed from its housing.
Keep the car's owner's manual handy. Remove the screws or bolts that hold the heater core in place. It may be that you need to remove more parts of the car in order to get to the heater core. Disconnect the intake and outtake hoses from the heater core. Remove the heater core from the car, taking special care to keep the core upright so no coolant spills out. Place the new heater core into the car, and reconnect the hoses as they were connected to the old heater core. Screw or bolt the new heater core into the car, and replace all the other removed car parts.

Drain the water from the cooling system. Remove the water hose from the heater core. Remove the heater core retaining bolts. Reverse the process to install the new heater core.
Up under the dash, to the middle.
Remove the glove-box door. Behind that is the heater core cover on the interior, passenger side of the firewall. Remove that cover and there is the heater core. Open the hood and look where the heater hoses enter the front right passenger area of the exterior side of the firewall. Disconnect the two heater hose clamps and you can then remove the heater core.
Remove glove box door. Behind that is heater core. Remove the cover,the core is right there. Under the hood, against the firewall you'll see the hoses going to the core. Remove 2 hose clamps then the core will come out from from the inside of your truck.

If you can find a '77 repair manual it shows how to do it. I did it and it was difficult. Seems like started under the hood first and it comes out under the dash, so have to take off the ducting.
If it is the same as a 92 F250 4x4 diesel it's actually pretty simple. First, take out the glove box by opening it and pressing inward on the two tabs at the bottom. Right behind there is some wiring, and a wiring module that needs to be disconnected and moved aside. After that is off the black plastic heater core cover can clearly be seen. There are about six screws that hold that cover on, a couple are a little difficult to get to. Once the cover is off you will see the core. Disconnect the lines in the engine compartment and with some effort, you will be able to pull the core out from behind the firewall (it is a little difficult as the clearances are a bit tight). Replace the new heater core, replace the cover, wiring and wiring module, glove box and connect the hoses. Run the vehicle until warm, and then double check the coolant level.
it is located above the heater core trap door behine the glove box.
