it is located under the dashboard against the firewall of the passenger seat. i recomend buying a repair manual from your local auto parts store before attempting as it requires draining, flushing, refilling and bleeding the cooling system as well as removing many other componets like the entire dashboard and thermostat

Not a whole lot different. Just need to keep removing plastic down at the heater until you get to the heater core. Then disconnect it on the firewall side.
