Adrian, we need a few more details. Got pics of what you did? How much air was the fan rated to move?

you know they have a auxilliary fan mine is all ways on wen the jeep is on wen it turns off it has no spark then wen it cool it does and it starts again they told me i need a 2 row radiator and a new thermostat it turns off wen it over heats

That is not working correctly. It needs to come on when the engine hits 217° or when the AC compressor is running. You need to check the relay that runs it I think for a start.

No, not really unless it is pulling hard when you do. Running in low range can require less energy due to gearing
