Electric vs Engine Driven Fan

This is something I have been back and forth on since I started planning the Econoline project. What's the consensus on them. I like the simplicity of an engine driven fan and not being concerned about electric motors, relays, sensors failing. But on the other hand a well design electric system, at highway speeds the fan may never turn on. What's your opinion

Electric is my choice.

coupled with an electric pump and you can cool the car with the motor not running. Also, when the it's cold out I leave the fan off.

A good clutch fan is hard to beat.

One thing I forgot to mention for those that don't know, this is not for racing. It's a highway vehicle for towing only.

I'm not sure in your case what would be the best but I have put over 300,000 miles on 2 1996 Taurus's with no problems with the electric fans and I believe that all newer vehicles use electric fans and they can't all be wrong! I think that it would be easy to use the electric fan with a temp switch and a manual by-pass switch just in case. Just my 2 cents.

i had a dual flex-a-lite setup on my lightning and it worked great.it was a variable speed deal so it never run hard unless the air was on in town on 100*day.

For what you are doing I really do agree w/Dave and the clutch fan.
