    Will installing an electric fan and removing the original belt driven one really save gas? How much?

    Like any modification, numbers vary. Fuel economy - perhaps 4%.

    It should, think about the resistance it gets when its spinning around pushing air through the radiator. Now take it off and relieve the engine of that strain, not to mention that if you put a dual electric fan on it will be that more efficiant at cooling. I have read of up to 1.5mpg increase.
