This used OEM Audi heater core coolant / water return hose, part number 4Z7819373C, was removed from a donor vehicle. Also known as the water return hose, it circulates coolant back from the heater core to the engine. A failure here typically causes a coolant leak and interior heating issues. This hose fits the Audi Allroad Quattro with the 4.2L 4172CC V8 gas DOHC naturally aspirated engine.
