This genuine Volkswagen coolant reservoir hose / line, OEM part number 3QF122109A, is a used OEM replacement for the 3.6L V6 engine in the Atlas and Atlas Cross Sport. Also known as a coolant line, this hose carries fluid between the reservoir and the cooling system. It also replaces 3QF122109 and 3QF122109B. A failing hose may leak coolant, leading to low coolant levels and potential overheating.
