According to an embodiment of the present invention, an engine cooling system comprises a cylinder block, a cylinder head, a thermostat, an integrated flow control valve, a heater core, an EGR cooler, an oil cooler, a water pump, a control unit, and a radiator. The radiator is separated into a block radiator which cools cooling water flowing from the cylinder block, and a head radiator which cools cooling water flowing from the cylinder head. The radiator is separated to individually cool the cylinder block and the cylinder head, thereby improving cooling efficiency. Moreover, by using the integrated flow control valve, flow of cooling water passing through each cooling device can be controlled for an optimum cooling circuit to be provided in accordance with an engine condition. |
