PROBLEM TO BE SOLVED: To inexpensively provide a vehicle cooling system for dispensing with air bleeding work by manual operation, and capable of bleeding air of a cooling water flow passage without largely changing a device constitution of the vehicle cooling system. SOLUTION: This vehicle cooling system 1 has a thermostat 4 for distributing a flow rate of a flow rate of cooling water flowing in a second flow passage 12 from a radiator flow passage 13 and a flow rate of the cooling water flowing in the second flow passage 12 from a bypass flow passage 14, a water pump 5 arranged in the second flow passage 12, and a reservoir tank 10 connected to the uppermost part of the radiator flow passage 13 via a pressure regulating valve 9b, capable of storing the cooling water and capable of separating air, and has an air bleeding control means for restraining the flow rate of the cooling water flowing in the radiator flow passage 13 by controlling at least any one of the thermostat 4 and the water pump 5.
