A thermal management system comprises a first coolant loop with a first pump, a second coolant loop with a second pump, and a refrigerant loop. A four-way valve is selectively configurable to maintain the first and second coolant loops separate, or to combine the first and second coolant loops in a single coolant loop operable with one of the first pump and the second pump. The refrigerant loop includes an inside condenser for conditioning air, and a chiller for extracting heat from coolant. The thermal management system is capable of operation in a plurality of modes depending on the thermal state of components heated and cooled by the thermal management system.
