To replace the heater core on a 2003 Pontiac Aztek, first, disconnect the negative battery cable and drain the cooling system. Remove the dashboard and the center console to access the heater core housing. Disconnect the heater core hoses from the firewall, unbolt the heater core from its housing, and then replace it with the new core. Reassemble everything in reverse order, refill the cooling system, and check for leaks.
Your Aztek heater core is dead center of the car behind the dash/floor console.
