This used OEM Audi coolant / water hose (4G0819342C) was pulled from a donor vehicle. It’s designed for 3.0L TDI diesel and 3.0L TFSI supercharged engines found in the A6 and A7 Quattro lines. As a coolant hose, it circulates engine coolant to maintain proper operating temperature; a cracked or leaking hose can cause overheating or coolant loss.
