Audi Coolant Supply Hose / Line, OEM part number 4H1819674AN – a used genuine part pulled from a donor vehicle. This hose carries engine coolant and can also be called the coolant line. It fits multiple 3.0L and 4.0L engines found in the Audi A8 and S8, including the 3.0 TDI diesel, the 3.0L supercharged V6, and the 4.0L twin-turbo V8. A failing hose often causes coolant leaks, overheating, or low-coolant warnings.
