Best to get the shop manual but basically: Reomove Heater hoses from engine block and drain. Remove glove box. Disconnect cables that connect to heater core. Disconnect heater core from firewall. Disconnect hoses from heater core. Pull heater core from under dash.
take heater hoses off the firewall heater box and unbolt heater box on the firewall and then pull heater box down from under the dash and you will see the heater core inside, replace it in the box and bolt everything back together.
you should only have to take loose the heater hoses where they go into the firewall and of course the heater core itself
