Maybe someone on hear can answer this.... Is there any reason we couldn't use the original Taurus Temp sensor (with a relay) to control these fans? It seems if we can use the fan in a First Gen, why not use the sensor/switch along with it to activate the relay to kick it on.
I looked into the DCC control, if I had the $140 to drop on it, that is the way I would go, but times are a little too tight right now to justify the money.
Seems too simple that someone else hasn't already done this, UNLESS there is a reason it won't work.
I don't want to spend the money on the sensor and connector if the sensor just sent a signal to a computer and the computer sent out a signal to relays to start the fan.

Any one have First hand information on this?

No reason at all not to use one, or a snap action surface switch at the temp range you select to open/close the relay.

I just learned a new term "Snap action surface switch" I had to look it up, but now I know what it is. Thank you for the input.
Does anyone know what temp the Taurus fan kicks on? Maybe that is why no one has talked about it?

low speed on a 94 3.0 engine, 215, shuts off at 210
high speed 230, shuts off at 224

Only to limit the number of Ford parts one has installed on his classic Chevy. ;)

BMW has a dual section temperature switch that could control both speeds with the same switch. You see a lot of these on the 90's models.
Volvo has a dual speed fan control module on their 850's that contains both the low and high speed relays with the interlocking logic, and inputs for the low and high temperature switches.

This is the route I took and it has been working great. :thumbsup:

But it has only been in the 60's when I had the car out. It's suppose to hit 91 degrees today though. :beers:

Thanks for all the replies. The standard Taurus temps sound too hot for these old cars, at least for my tastes. I usually run a 160 -180 stat. The 200+ temps would worry me. Now I know why I haven't seen much discussion about them.

HPCam...... Let me know how it does with the high temps, do you know at what temps the fans kick on?

I did a ton of searching on line for a diagram on how to wire the relays for the 2 speed fan switch switch. I found bits and pieces in different places. but no clear cut diagram. Using different info from a few different places I drew up my own diagram. I drew the sketch, but all the ideas came from other people, My thanks to them.

Diagram has now been corrected. Thank you onovakind67 for pointing it out

You need to modify the wiring if you want it to work correctly. The way it is shown, the high speed will be on as soon as you turn on the ignition. You need to swap the 87a and 87 wires on your Aux relay.

I can't argue with facts, I drew it wrong, I'll fix it and repost.
