Abstract
Methods and systems are provided for a cooling system for a vehicle engine. In one example, the cooling system includes a coolant solution circulated through both an engine cooling circuit and a vehicle interior heating circuit that is fluidly coupled to the engine cooling circuit, and a reservoir containing concentrated antifreeze. The concentrated antifreeze is flowed from the reservoir to the vehicle interior heating circuit via a shutoff valve to increase a concentration of antifreeze in the coolant solution. In some embodiments, a separation unit may be used to decrease the concentration of antifreeze in the coolant solution.
