To replace the heater core in a 2004 Chevy Aveo, start by disconnecting the negative battery cable and draining the cooling system. Remove the dashboard and the center console to access the heater core, then disconnect the heater hoses and any retaining clips. Replace the old heater core with the new one, reassemble the dashboard and Plumbing, and refill the cooling system before reconnecting the battery. Finally, check for leaks and ensure proper operation of the heating system.
