Abstract
A cooling system for a vehicle, includes a first cooling circuit including a first coolant passage and a first pump. The first pump is provided in the first coolant passage to circulate coolant in the first cooling circuit so as to cool a first device to a first temperature. A second cooling circuit includes a second coolant passage and a second pump. The second pump is provided in the second coolant passage to circulate coolant in the second cooling circuit so as to cool a second device to a second temperature. The second temperature is lower than the first temperature. The coolant introduction passage connects the first cooling circuit and a connected portion of the second cooling circuit between the second device and a second radiator and upstream of the second device to supply the coolant in the first cooling circuit to the second cooling circuit.
