Description
Replacing a leaking heater core behind a Jeep dashboard is labour-intensive, so the correct HVAC-box configuration matters. Crown 4874045 is the aluminium heater core for specific earlier TJ and XJ models with left-hand drive.
The part is the heat exchanger inside the heater system rather than a full HVAC housing or blower motor. Crown lists one unpainted aluminium core and specifies reusing existing attachment hardware.
