This used OEM Audi radiator coolant hose / line (upper) carries part number 4K0122101AT. Also known as the upper radiator hose, it was removed from a donor vehicle. Designed for the 3.0L 2995CC V6 MHEV DOHC turbocharged engine, this hose directs coolant from the thermostat housing to the radiator. A cracked or collapsed upper hose can cause coolant leaks, overheating, or low coolant warning lights.
