Where is the heater core located in 1986ford Taurus?
It is lo cated behind the dash. There is no short cut or fast
way to replace it. 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 evacuate the freon out of the AC system, disconnect the
heater hoses, disconnect the AC lines and AC drier from the evap
core fittings, remove the dash, remove the entire AC/heater box,
open the top of the case and replace the core. Reassembly is in the
reverse order as disassembly. Recharge the AC system, fill the
cooling system with new coolant, and burp the air form the cooling
system.
