Very simple ,   located near the gas pedal .  Drain coolant, remove hoses, and 2 or 3  small 5/16 " screws hold the heater core in place.  Make sure you bleed all the air out when done. With the new core in place, and one heater hose installed, fill the system until you see coolant coming out of the core. Then simply install the other hose. Top off coolant. And re-check after thermostat opens.
