This BMW coolant expansion tank hose/line (OEM 2284692) is a used genuine part from a donor vehicle. Also known as the expansion tank line, it routes coolant between the tank and the engine’s cooling system. When the hose develops a leak, it can cause gradual coolant loss, leading to overheating. This example came from a 3.0L 2979cc turbocharged inline-six—the engine found in the BMW M3 and M4. A cracked or swollen hose should be replaced immediately to prevent engine damage.
