Heater core is located under the dash and is held in with i believe 4 bolts which means the bottom half of dash needs to be removed but first you need to pop the hood and disconnect the inner and outter hoses going to and coming from the heater core at the wirewall, be ready cause some Coolant will come from the hoses.
