This used OEM Heater Core Coolant Return Hose (Audi part number 4F0819373P) was removed from a donor vehicle. It also replaces earlier part 4F0819373D. Designed for the Audi A6 Quattro with the 4.2L V8, this hose returns coolant from the heater core back to the engine. When it cracks or develops leaks, it can cause low coolant levels, interior heat loss, and potential engine overheating.
