should be blowing towards the motor....its a pull design that pulls air from the radiator and directs it towards the motor.

Right. you want to push air too the motor, not take it away.

Think about this. If you make the fans push air toward the front of the vehicle. Whats going to happen to that air when your driving 65mph down the road?

Just turn your Ground and Positive around on your fans to go the other direction.

pullers are your only way to keep them efficient. .. .so you have head wind cool the front while the fans are off

The whole purpose is to pull air through the radiator, it has nothing to do with air moving over the motor. Like said above, swap the power and ground on the fans.

Right. Just seemed easier to say Toward the motor cuz technically the way it is now is blowing air Through the radiator. Just in the wrong direction
