SOURCE: removing/replacing a 2000 kia sportage 4x4 4 dr heater core

The heater is located under the dash board to the right and down from the radio. To remove and replace it you will have to remove the dash board down to the fire wall. Also, you will have to disconnect two hoses that connect up to it from the engine compartment. These are located in the back of the engine and down on the firewall about midway. Once you remove the dash board and locate the heater core you will be able to see the location of these two hoses. Removing the heater core is time consuming but it will save you about 700 dollars.

SOURCE: 1994 buick lesabre heater core removal

The heater core is located under the dash, in the center. The container holding the core looks like a black plastic box. Remove the ash tray for easier access. You may have to also remove some other covers under the dash. You must first drain the radiator then you have to disconnect the hoses. There are two hoses connected to nipples of the heater core that go thru the center of the firewall. Remove the screws that hold on the cover to the heater core. Then you should be able to get the old one out. There might be a couple of other minor steps but I'm sure you can figure them out. For re-installation just go in reverse order to put it all back together.

Heater core replacement on a 2003 ford sport trac


the complete climate control assembly unit is required to be removed in order to remove the heater core. The climate control assembly is attached by studs & nuts which are accessible at the firewall in the engine compartment. The R134 refrigerant will need to be evacuated and the a/c lines at the expansion valve removed in order to remove the climate unit. Hope this helps. :)
