Try flushing the coolant system out
To change the heater core in a 87 ford f150 is easy. Just remove the glove box and then behind it there is 7 bolts. After you remove the 7 bolts then just remove the cover and behind it is the heater core. By far the easiest heater core I ever changed.
There is no short cut or fast way to do this. The dash has to come out to access the heater box and replace the core. So the steps in replacing the heater core are to disconnect the heater hoses, remove the dash, to access the heater core cover on the front of the heater case and replace the core. Reassembly is in the reverse order as disassembly. Fill the cooling system with new coolant, and burp the air form the cooling system.
Take it to a mechanic and say "will you fix the heater core?"
