I have a 84 F 150. It has a 302. The heater will not get hot at all. I replaced the thermostat. Radiator is full. But still no heat. I've been told the heater core may be clogged! Any ideas? And how do I get the heater core out. Its in an enclosure under the hood but i dont see any bolts under the hood to disassemble it.
a new thermostat can be bad,try another one,dont use stant parts,no on heater core,maybe the heater control is bad.
