Used Mercedes-Benz coolant reservoir tank hose, line, or pipe, OEM part number 2782030103. This genuine used part also replaces 1572030002. It connects the coolant expansion tank to the engine's cooling system, routing coolant to maintain proper operating temperature. A cracked or leaking hose can cause low coolant levels, engine overheating, or visible puddling under the vehicle. This is a direct OEM replacement, not an aftermarket copy.
