Claim:
1. A vehicle engine cooling system comprising: a high temperature radiator in which a high temperature coolant for cooling an engine by using ambient air flows; a low temperature radiator in which a low temperature coolant for cooling a water-cooled condenser by using ambient air flows; an integrated cooler configured to cool a low pressure EGR gas and air which has passed through a turbocharger by using the coolant of the high temperature radiator and the coolant of the low temperature radiator; a high temperature radiator circulation line provided to allow the high temperature coolant to circulate the high temperature radiator, the engine, and the integrated cooler; a low temperature radiator circulation line provided to allow the low temperature coolant to circulate the low temperature radiator, the condenser, and the integrated cooler; a plurality of control valves provided on the high temperature radiator circulation line and the low temperature radiator circulation line to control flows of the high temperature coolant and the low temperature coolant; and an ambient air intake configured to allow ambient air in front of a vehicle to be introduced to an engine room and side ducts formed to be symmetrical to guide ambient air in front of the vehicle toward a wheel of the vehicle, wherein the high temperature radiator includes:
