Best Answer

You remove the bottom panel of the heater box under the passenger side dash. It is about 6 or 7 screws. Once the panel is off you will see the heater core. It has a clip at the top you loosen. You must remove the 2 hose clamps in the engine compartment before it will come out. The new ones usually do not come with the foam padding on top of the core. Use some RTV or spray glue and carefully pull it off of the old one, and put on the new.
