BMW Radiator Coolant Hose / Line (return), OEM part number 9329646 — a genuine used coolant return hose salvaged from a BMW. Also called a coolant line or return hose, it channels coolant from the radiator back to the engine. A common failure symptom is a coolant leak at the hose ends, which can cause overheating. This return hose fits the B46/B48 2.0L turbocharged four-cylinder engines found in BMW 230i, 330i, and 430i models, including the plug-in hybrid 330e.
