Remove the glove box and the lower dash panels. You will see a panel on the AC case with two or three screws in it. Remove the heater hoses first then removed the panel you will see the heater core and inside. Just remove the retaining screw and slide the core out. Then slide the new one in secure it and put the panel back on the AC case. Reinstall the hoses.
