An apparatus for controlling an electric cooling fan of an automotive vehicle with an engine, having a radiator facing the electric cooling fan for cooling the engine coolant, comprising a device for generating an engine start signal, a coolant temperature sensor for sensing the engine coolant temperature, a judgement device responsive to the engine start signal for comparing the coolant temperature with a preset temperature, and generating a first judgement signal when the coolant temperature is lower than the preset temperature, a cooling fan control temperature setting device responsive to the first judgement signal for setting a cooling fan control temperature in accordance with the coolant temperature, the cooling fan control temperature being set higher with lower coolant temperature at the engine start, a temperature judging device for comparing the cooling fan control temperature with the coolant temperature after engine start and for outputting a second judgement signal, and a device responsive to the second judgement signal for driving the cooling fan.
