A used OEM Audi coolant hose/line, part number 4G0121448AH, is a genuine factory component for the left side of the engine bay. This hose carries engine coolant through the supercharged 3.0L V6 or turbocharged 4.0L V8 in Audi A6, A7, and S6/S7 models. When this line develops a leak, you may notice low coolant levels, overheating, or a visible puddle under the front left of the vehicle.
