How to replace a heater core on a 94 Lincoln mark8?
The heater box was preassembled and shipped to the Lincoln plant for assembly. The box is installed as a unit then the dashboard is installed...... Get the picture? You have to take the dashboard out and disassemble the heater box to get the job done. I advise a trip to your local library for instructions for your needs first! Not much else to say... Good luck!
You have to take out the whole heater and air condiasioning system out and replace the new heater core in. When you replace the heater core, you firset have to put the air condiasoning system in then the heating system/ heater core. When you take the old systems out, you first have to take out the A.C then the heater.
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…
