If it is just an odor I think I would try some cooling sytem sealant. Usually costs about $3 to $5.00. With the engine running and hot with heater on, open the container and pour into the overflow and let engine run for another 15 minutes or so. DO NOT REMOVE THE RADIATOR CAP; YOU MAY GET SCALDED!!!!!!! Do not open the sealant container before you are ready to use it, it hardens quickly.

SOURCE: heater core
it is located under the dashboard against the firewall of the passenger seat. i recomend buying a repair manual from your local auto parts store before attempting as it requires draining, flushing, refilling and bleeding the cooling system as well as removing many other componets like the entire dashboard and thermostat

Unfortunately, this is one of the most complex and time consuming operations, short of changing the engine/transmission that can be done to the car.
The heater core is mounted in a box, inside the passenger compartment, almost dead center behind the dashboard and is mounted directly on the firewall to allow the hoses to go through. If you put your hand just above the accellerator pedal, and go toward the center console, you'll find the heater core box.
There is no way to remove the heater core from the engine compartment. In fact, other than draining the radiator and removing the hose clamps and a bolt or two, youll have little interaction with the engine compartment.
Begin by disabling the air bag system, by removing all power from the vehicle. Be SURE the air bags are disabled as they are extremely dangerous if they activate while you are working under the dash.
Next remove the entire instrument panel, and all the decorative plastic. To do this you may have to remove the steering wheel also. Be sure to label everything as you go. Then remove all the heater controls. Once done, you should be able to access the black heater box that the core rests in. Remove that, and if you have loosened the hoses and screws in the engine compartment, the heater core will come free and you can replace it.
For a much better and more detailed explanation of how to do this, I used the Haynes Repair Manual. (Note, Im not affiliated with them, they just had the best description of the procedure.)
I dont really recommend doing this yourself unless you are a very patient and reasonably accomplished mechanic. This will involve removal of all the dash, instruments and controls, and frankly, even when the dealer did this, the car is never quite the same again.
One other hint, after replacing the heater core, use a length of good heavy copper wire to wrap around one of the hose entry points (metal to metal contact) and then ground the core to the engine block or frame. This will help prevent the electrolysis that killed the core the in the first place.
