YOU NEED A SHOP MANUAL..OR AT LEAST READ HEATING/COOLING SECTION. THE HEATER CORE IS LOCATED (GENERALLY) UNDER THE DASH ON PASSENGERS SIDE. YOU MAY HAVE TO REMOVE A FEW COMPONENTS,OR MOST OF THE DASHBOARD.

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: heater core replacement

Actually if your handy the heater core on this car is pretty easy..  passengers side under the dash... but here is a link to some sites that will probably help  
from .... one of the wikki sites.. LOL cant remember which now

The heater core is located under the dash, in the center above the "hump". 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. First drain the radiator. Then you have to disconnect the hoses. There are two hoses connected to nipples of the heater core that are thru the center of the firewall. This has to be done from underneath the car while raised. I also had to unbolt a frame support to get to the hose clamps (I have big hands; you may be able to reach them without unbolting it). Remove the screws that hold on the cover to the heater core. You should be able to get the old one out now. Just go in reverse order to put it back together.

also this link is very handy they have a pretty complete collection for MANY vehicles

Heater Core - REMOVAL & INSTALLATION
1994-97 Vehicles
(see Figure 1)

44d2ba8.jpg

Fig. 1: Exploded view of a common heater core and case assembly
  1. Disconnect the negative battery cable and properly drain the engine cooling system to a level below the heater core.
  2. Disconnect the heater hoses from the core tubes near the cowl.
The instrument panel carrier is designed not only to provide access to parts through removal of the carrier components, but the carrier will also tilt downward as a complete assembly to allow access from the top. If this is desired, remove the retainer screws along the top and bottom of the carrier assembly (refer to the figure). The instrument panel will then tilt as an assembly into the cab. It is necessary to unbolt and lower the steering column from the carrier to allow for maximum movement of the instrument panel.
  1. The instrument panel must be removed or repositioned for access to the heater core case. Unbolt and either tilt the instrument panel forward or disengage the instrument panel components and remove the panel from the vehicle. In most cases, tilting the panel forward should be sufficient for the necessary access.
  2. Unfasten the heater core rear case retaining screws, then remove the rear case for access to the heater core.
  3. Loosen the retainers and remove the heater core retaining straps.
  4. Remove the heater core and seals.
To install:
  1. Install the heater core and seals, taking care not to damage the core tubes when inserting them through the cowl.
  2. Install and secure the core retaining straps.
  3. Install the rear case and secure using the screws.
  4. Reposition and secure the instrument panel and components. Tighten the cowl screws to 17 inch lbs. (1.9 Nm) and the lower instrument panel screws to 66 inch lbs. (7.5 Nm).
  5. Connect the heater hoses to the core tubes.
  6. Connect the negative battery cable, then properly refill the engine cooling system.
  7. Run the engine at normal operating temperature, then check for leaks.

Good luck (remember rated this post).
