Thanks guys I think I'll give a try. I only need the extra air flow when it gets real hot, other wise I have no problems.

My radiator has never boiled over but the guage goes up midway into the red sometimes. I probably should check the actual temp of the water in the radiator when the guage shows hot before I go to the expense of buying a fan.

The radiator has been rodded out and a new filler neck installed so that I can run a 7lb cap.

Thanks
George
