The general populaces understanding of *what* a thermostat is, and actually does, is kinda weird, i've seen all sorts of people and given reasons for using a lower thermostat - most don't make sense.

Thanks for making the comments, if no one discussed this, we'd get no where, i'm all for discussion :)
Understand that this is one thing that is pushing me to an EFan, not the only thing, i will still look at the reasoning/causes of this 'problem' and i do appreciate the differing issues i can introduce with this setup.

I'm curious about loads though, for example, the Taurus has a 75a alternator, Vs the Rangers 95a - whilst trim configurations change this, just what are the chances that my truck has more general power draw (by default) than a Taurus with electric everything?
I will add my truck is a base model with power nothing

Just ordered a DCControls FK75 and a Contour fan. Will post some pictures when I get a chance to do the install. Rumor is that DCC takes some time to build and ship the controllers so it may be a little while.
Sounds interesting, feel free to post anything in here with what you get, did you order a new Contour fan?

Should be the same if both are healthy.

The other test, remove the clutch fan (left hand thread) and run the engine and see if that changes the warm up time.
The clutch fan on mine is independent of the pulley.
If it is left hand thread, there is a warning on the rad shroud.

Why bother going to all that work putting in electric fans, the other one works fine.
If i remember, i want to do the pan test, i ordered a new one last night as you've previously helped me in regard to the thermostat questions.

The very design of a mech fan, even clutched, to me, doesn't work fine. That's just me though, i come from a land and a history of essentially no mechanical fans, as a general rule, they're horribly inefficient, the EFan is a cool play/project/upgrade to me.

I picked up a used one on ebay for about $50.

you can test the load on the electrical system...
