According to an embodiment of the present invention, an engine system having a coolant control valve comprises: a coolant pump; a cylinder head; a suction cylinder block; and a coolant control valve. The coolant pump pumps a coolant. The cylinder head is provided with the coolant pumped by the coolant pump from a first exhaust side water jacket and discharges the coolant to a first suction side water jacket. The suction cylinder block is provided with the coolant pumped by the coolant pump and receives the coolant from and discharges the coolant to a second suction side water jacket. The coolant control valve selectively blocks the coolant discharged from the first suction side water jacket of the cylinder head and the coolant discharged from the second suction side water jacket of the cylinder block and controls each coolant supplied to at least two heat exchangers. The heat exchanger may comprise: an oil cooler for cooling oil; an exhaust gas recirculation (EGR) cooler for cooling recirculated exhaust gas; a heater core for heating the interior; and a radiator radiating heat of the coolant to the exterior. According to the present invention, the cooling efficiency of an entire engine can be improved and fuel consumption can be reduced.
