PROBLEM TO BE SOLVED: To provide a cooling device for a vehicle capable of efficiently and precisely cooling a heat exchanger for cooling by using an electric fan small in output, even on the vehicle with an engine of large cubic capacity, in stopping/starting the engine in accordance with an engine stopping condition and an engine starting condition. SOLUTION: A cooling controller confirms whether travelling speed exceeds set speed and refrigerant pressure of a condenser exceeds set pressure or not when the engine stopping condition is established and the engine is stopped and carries out cooling driving the electric fan when the travelling speed is lower than the set speed and the refrigerant pressure exceeds the set pressure. Additionally, it cools the condenser by a mechanical fan by demanding starting of the engine (step 116) when the refrigerant pressure exceeds the set pressure in a state of driving the electric fan and cancels the engine starting demand as the refrigerant pressure falls lower than the set pressure (steps 120 to 124).
