More Information
Summary:A cooling system for an internal combustion engine includes a coolant flow passage through which coolant flows between the internal combustion engine and a heat exchanger, a flow amount control valve incorporated in the coolant flow passage and configured to control flow of the coolant flowing in the coolant flow passage, and a control section configured to effect switchover from a full opened state to a full closed state of the flow amount control valve based on a supply of a negative pressure produced in the internal combustion engine and to effect also switchover from the full closed state to the full opened state over a second period longer than a first period required for the switchover for the flow amount control valve from the full closed state to the full opened state, in response to stop of the supply of the negative pressure.
