Abstract

A cooling system of an internal combustion engine includes a first flow passage supplying a cooling medium of the internal combustion engine to a radiator, a second flow passage branching from the first flow passage by a flow control valve to supply the cooling medium to a first heat exchanging portion, a third flow passage provided separately from the first flow passage to supply the cooling medium to a second heat exchanging portion via an on-off valve and a control portion controlling the on-off valve and the flow control valve based on a temperature of the cooling medium.
