Used Mercedes-Benz Coolant Vent Hose / Line, OEM part number 1772030317. This genuine used hose was removed from a donor vehicle. It serves as the coolant vent line, routing excess coolant and air from the engine's cooling system back to the expansion tank. A failure in this hose can cause a coolant leak, leading to overheating or low coolant warnings. It fits multiple Mercedes-Benz AMG and G-Class models equipped with 4.0L, 4.7L, or 5.5L V8 turbocharged engines.
