Just putting the final touches on the winter project. I am now wiring the fan up, which is a black magic 185 extreme. I had a bit of a colloing issue with it before the new motor and now have added a hi flow water pump to go along with my electric fan although to solve the problem for sure I know I should have an aftermarket rad but I am facing clearance issues so I was wondering if i were to switch the polarities of the wires to make my fan push air through the rad from the engine side outwards do you think this might help to furthermore cool the car apposed to the fan pulling the air through the rad? I hooked it up to my battery with my fan attached to the rad and it seems to push more air then it pulls that is why I am asking this question.
