This Audi heater core coolant return hose (OEM 4Z7819373B) is a genuine used line from a donor vehicle. Designed for the 2.7L V6 turbo in the Allroad Quattro, it carries hot coolant back from the heater core to the engine, completing the heating circuit. A cracked or clogged hose can cause coolant leaks, low cabin heat, or engine overheating.
