What are you using to control your Taurus fan?

Snabbed a Taurus fan for the Moss and am ready to begin, but need a controller (1227747 ECM has no provision for E-fans)...

I'd LOVE something "automatic" = programmable make/break/offset temps, replaceable/upgradeable relays, fires either speed based on temp... Seems some folks just live with replacing cheapies often. Others go for the defacto controller, DCC, but the guy is very hit/miss on communications, could take months to get it, & they ain't exactly giving them away!
I'm not opposed to full manual (using relays), but figure I'd eventually forget and have a meltdown... :rolleyes:

What are you using?
Why?
Any issues?
Likes?
Dislikes?
 
Kept mine simple. Run it thru a relay, continuous duty, think it was a Ford application. Triggered thru a temp sensor in the block. On/off at around 185. Just looked thru the book at NAPA to get the temp switch that had my threads and the temp I wanted.

Also have a manual switch (on-off-on) on the dash...can cut off in water, or turn on manually. Down=automatic, center=off, up=manual on.
 
Flex a lite and painless have nice looking controllers. I have no experience with them other than preliminary research. For a cheap foolproof method though 80s camaros with 305 tbi used a temp sender screwed in a head to ground the fan relay around 210 degrees. It looked and functioned like the sender for an idiot light just comes on at a lower temp than 260.
 
I'm running dual 40amp cheap relays in parallel to distribute the load, even though I use to run just one with no problems. I have an on/off switch on the dash, but no temperature, just always on. Thats what the thermostat is for, right?
 
I had the one on my YJ set up so that the low speed was always on with the key so I could not forget to run it. The high speed was run off of a cheap adjustable controller from autozone. It would come on at about 220 or so. I had a manual cut off switch on the dash for water crossings that would kill all power to high and low.
 
I run mine on high all the time. I love the sound.
 
While mine is a BMW fan minus the stock controller (That catches on fire), I am using a thermostat from Advance that just has an air temp probe zip tied to the fan shroud. The relay in it was only rated at 15 amps so it controls a 60 amp relay that controls the fan. I also have a manual cut off switch for water or when on the highway for long periods of time as the fan doesn't shut off even driving at highway speeds. (I can watch it cycle through my voltage gauge.)
 
Think I'm gonna use a "3 Relay" setup with...

- LOW = relay #1 actuated by intake mounted snap switch (185*F ON/170*F OFF)
- HIGH = relays #2 & #3 (parallel) actuated manually, but will disconnect relay #1 (low) during switching
- OFF = on same switch as high

The plan is to test this out on the Mustang before the Jeep... priorities! :lol:
