To change the heater core in a 1998 Ford Ranger, first ensure the engine is cool and disconnect the battery. Remove the dashboard components to access the heater core, which typically involves removing the center console and the dashboard itself. Disconnect the heater hoses from the old heater core, remove the mounting screws, and take out the old core. Install the new heater core by reversing the removal process, reconnect the hoses, and reassemble the dashboard.
