hit up a junkyard and pull all of the parts out of a car with an electric fan set up. If you are good at following wires, then you will find the thermostat for it too. The key thing is to get a fan that will fit on the radiator. Don't do the dumb thing I did and get a whole set up just to find out the fan was too big... I had to go back and get some taurus fans and wire those in.. lol...
