Got a line on a couple of Ford Windstar cooling fan assemblies for my cooling system upgrade. What is the difference between the 95, 96 and 97 models if any?
 
i have the 97 in mine but haven't figured out how to get the big two speed fan to work on high and low. only one speed don't know if it is high or low the plug only has two wires but the fan has three contacts the one in the center not used

I have found out that 95-98 are the same.
As far as wiring goes. See if the following 2 links help you. They are from a website from another member of this board. I don't remeber exactly who it was to give him proper credit, I only saved the links when I read it a while ago.

Fan information

Wiring information

Check out the link in the post above yours also. He has info on the dual fan install and wiring also
 
the wiring is in-correctly shown for the 2 speed motor, the 2 power prongs are tied together.. they only run low and high if you run a resistor in line with one of them.. basicly they run high speed all the time unless you want to just waiste power thru a resistor.... i pulled mine apart and actualy checked these i wanted to run them low/high too if it wasn't too much work but turns out they are the same...

The wiring is incorrect for which diagram? Yours or the other link I found?
 
thanks for the link epistuff i will give that a try. chev-hell i think i lost somthing in your explanation "they only run low and high if you run a resistor in line with one of them.. basicly they run high speed all the time unless you want to just waiste power thru a resistor.... " I don't understand:clonk: are you saying that they are wired in the fan to run on high all the time with just one wire connected without a resistor?
 
that sounds right, the fan just has one speed but you can run one of the small power wires through a resistor before it meets the second wire to make a low speed by providing the fan with less electric power, then when switched to "high" it would direct current through the non-resistor wire to provide full power to the fan so it runs "high"

thats what I understand anyway...
 
yes, the 2 prongs on the positive side are basicly parallel, just 2 terminals for 1 set of windings... what ford did i think is use 1 wire running a resistor thru it to get a lower speed, then when switched to the other wire it had nothing in it's way... hard to say how it was wired up from Ford, but basicly you could make any fan a 2 speed, but i'd just run it high all the time, just run 1 fan at a time though, my pics write up are a bit old, im now running 2 75 am relays, and diods for bleeding off the excess juice when they shut down and turn into generators.. 1 fan comes on when the engine is running only above 500rpm (msd rpm switch) and the other comes on only when running AND the temp is over 180ish... thru a temp switch in my radiator hose.... so basicly 1 is running all the time and i't's pleanty of pull if it's not real hot outside, when the 2nd fan comes on it'll cool down REAL fast :)

i just checked and the link says apply voltage to just 1 tab for LOW and both for HIGH, this is wrong, i know for a fact, done checked it out before i re-installed mine while i was putting the diodes on.... there's another diagram somewhere i remeber white/blue that i'd like to see again though..... i think it needed a few "changes" also.

How did you mount a temp switch in a hose?

bump,...see my question in the reply above this one. :)
