inside. under the center of the dash is a cover panel that you remove. you then have acess to the heater core cover. remvoe that and the heater core is there. outside you must disconnect the hoses at the neck. be carefull and drain the system. it pays around 2.5 hours for a pro to do it so double the time if you have no expierence.
