This is a used OEM coolant tube, also known as a water pipe or line, with part number 5Q0121070BQ. It replaces the earlier number 5QD121070B. This genuine component routes engine coolant through the cooling system. A common failure on this part is a plastic crack or leak at the connection point, which can cause a loss of coolant and overheating.
