Used BMW radiator coolant hose / line (return), OEM part number 9329643. This genuine used part is the return line for the engine's cooling system, routing coolant back from the radiator to the engine block. It fits the 2.0L turbocharged four-cylinder engine family found in several 2, 3, and 4 Series models. When this hose fails, a common symptom is a coolant leak at the connection point, which can lead to engine overheating.
