    When the cooling fan does not turn on, your thermo fan switch is bad. It is located on the engine
    block or radiator. Reconnect the original cooling fan power connector. One can test it by
    short wire across the fan switch terminal. If the fan turns on, your cooling fan relay might be bad.

    When one is changing the coolant or flushing the radiator, the air bleeder screw must be loosen
    when putting the coolant into the radiator. Having the toggle switch to turn on all the time, might
    interfere the cooling system. At high speed , much of the air is force into the radiator to cool the
    radiator. If the head gasket is bad, you probably will have the white smoke or loosing coolant.
    I hope this might help.
