Cooling control system for internal combustion engine

A cooling control system for an internal combustion engine that includes a supercharger, the cooling control system being provided for cooling intake gases which have been increased in temperature by being pressurized by the supercharger, comprising:

• an engine cooling circuit that includes an engine main unit, a first radiator, a first coolant passage connecting between the engine main unit and the first radiator, for causing coolant to circulate therebetween, and a first pump provided in the first coolant passage, for delivering the coolant to thereby cause the coolant to circulate;
• an intercooler cooling circuit that includes an intercooler for cooling the intake gases, a second radiator, a second coolant passage connecting between the intercooler and the second radiator, for causing coolant to circulate therebetween, and a second pump provided in the second coolant passage, for delivering the coolant to thereby cause the coolant to circulate;
• and
• a plurality of connection passages connecting the first coolant passage and the second coolant passage, for causing the coolant to flow from one to the other of the engine cooling circuit and the intercooler cooling circuit,
• wherein the plurality of connection passages include:
• a coolant inflow passage that is connected between downstream of the first pump and also upstream of the first radiator of the engine cooling circuit, and downstream of the second radiator and also upstream of the second pump of the intercooler cooling circuit, for causing the coolant in the engine cooling circuit to flow into the intercooler cooling circuit;
• and
• a coolant outflow passage that is connected between downstream of the second pump and also upstream of the second radiator of the intercooler cooling circuit, and downstream of the first pump and also upstream of the first radiator of the engine cooling circuit, for causing the coolant in the intercooler cooling circuit to flow out into the engine cooling circuit,
• the cooling control system further comprising a valve that is openably and closably provided in the coolant inflow passage, for being opened when the coolant in the engine cooling circuit is caused to flow into the intercooler cooling circuit.
