  • Procedures for replacing the heater core vary with the year, make, and model of car. It threfore necessary to consult the manufacturer's repair manuals for the proper procedure for replacement.

  • Remove the heater coolant hoses.
  • Remove the cable and/or vacuum control lines (if equipped).

  • Lift the core from the case. Do not use force. Take care not to damage the fins of the heater core when removing.

What does a heater core do?


The heater core runs off of the cooling system, it is a small "radiator" behind the dash that sits in a box. when the heater core is full of hot coolant, it gives off heat and the blower motor pushes the hot air to the vents.

If a heater core ruptures, becomes clogged with parasites, or gets blocked in a hose (the 2 leading to the firewall under the hood on the passenger side) it causes the car to overheat, and/or leak.

my suggestion is to have the system pressure tested, and flushed if it checks out OK
