A cooling system is provided with a plurality of layered assemblies for simultaneously cooling both a power module and a vehicle motor. A first layer, a second layer, and a third layer each define upper and lower opposing major surfaces, and are positioned in a stacked arrangement and configured to provide a flow of coolant fluid from a fluid inlet, defined in the third layer, through an inner region of the second layer, and to a heat sink feature disposed in the first layer. The coolant fluid is then directed back through an outer region of the second layer and to a fluid outlet defined in the third layer. The first layer is in thermal communication with one of the power module and the vehicle motor; the third layer is in thermal communication with the other of the power module and the vehicle motor.
