Methods and systems are provided for an expansion reservoir for an engine cooling system. In one example, a cooling system may include a first cooling circuit and a second cooling circuit, the second cooling circuit configured to operate at a different temperature than the first cooling circuit, wherein the expansion reservoir is configured to receive coolant from and return coolant to the first and second cooling circuits. The expansion reservoir may further comprise one or more valves arranged so as to control the flow of coolant from the second cooling circuit to the expansion reservoir and/or from the expansion reservoir to the second cooling circuit depending on the temperature of the coolant.
