A used OEM Audi A6 Quattro coolant hose / line, OEM number 4K0819374Q, from a donor vehicle. This genuine coolant line circulates engine coolant through the 3.0L 2995cc V6 MHEV powertrain, connecting the engine block and radiator to maintain operating temperature. When this hose fails, coolant loss and engine overheating are common symptoms.
