Your Mercedes ML320 expansion tank is a vital component in your car's cooling system. The coolant in your cooling system absorbs heat from your engine and, as it does so, the coolant expands in volume. This expanded volume into the expansion tank, which allows the pressure inside the radiator to remain at a fixed level while also allowing any air bubbles trapped in the coolant to rise to the surface and escape.
