A process and apparatus for cooling a heat generating component of a vehicle comprises pumping coolant from a first pump while a first pump is in a chiller mode in a first loop comprising a component heat exchanger and a chiller module. Coolant is pumped from the first pump while the first pump is in a recirculation mode in a second loop comprising a heater module, and a cabin heat exchanger or back to said component heat exchanger. A second pump pumps coolant in the second loop while the second pump is in an isolated mode and from the second pump from the second loop into the first loop while the second pump is in a linked mode.
