While not all vent fans can reverse their blade direction, certain fans that use alternating current (AC) motors can, such as a 110-volt AC motor and certain shaded pole motors. Fitting a fan the wrong way round does not cause it to 'suck' air in the opposite direction, just means it ⦠It is still blowing air through the radiator from the engine bay, but at a reduced flow because the fan blade angles are incorrect.
