An engine cooling system, capable of suppressing increase in vehicle weight caused by employing a Rankine cycle and capable of improving Rankine cycle performance, has a configuration whereby in a vehicle (1) employing a Rankine cycle (32) and using some inlet-side cooling water (33) of a radiator (3) as a heating source for a first evaporator (28) and some outlet-side cooling water (34) of a sub-radiator (2) as a cooling source for a first condenser (30) : a second coolant (40) that has passed through a second expander (37), a second evaporator (38), and a compressor (39) in a cooling cycle (41) for an air conditioner and vaporized is cooled and liquefied by passing through the side to be cooled of the first condenser (30) in the Rankine cycle (32). |
