I had all intentions of making a shroud for the T-fan on my ZJ. Never did. Never needed to. Amazing cooling power and that was just with the low speed.

Some of the Dakota-Durango guys have used commercial cookie sheets that fit their radiator perfectly, and cutting out for the Taurus shroud. I really like the idea, but haven't found anything that fits the WJ radiator dimensions.

Well here's the pictures. Please excuse the ghetto wiring. I've pulled a lot of wire loom off of things to re-route some stuff, and am planning to upgrade the battery and alternator wiring whenever I find the time. I'll clean it all up and update pics when it's done.

View from driver's side. The temp probe for the thermostat is mounted up near the water inlet at the top of the radiator, behind the fan.


Here you can see the bare wire for the temp probe, and the adjustable thermostat that I (temporarily) mounted to the top of the radiator.



Look at all that extra room!



Here's a shot showing how much radiator isn't covered:



From the passenger side:



I mounted the fan straight up and down, with the fan on the top side. This allowed me to kinda wedge it between the radiator and steering gear, then I zipped 2 self tapping screws in the top to hold it in place. It's very solid mounted this way.

I believe once I have a shroud built, and seal up the open areas in the Taurus' molding (see last pic near the top of the radiator), then I'll be in business.


NOTE: I did only wire up the high side, and I've got a 40A relay and fuse powering it. That seems to work just fine. It did keep blowing 30A fuses, and melted a 30A fuse holder I had. I've been thinking about hooking up a 12v light to the low side to see if it'll output any voltage, to use as an in-cab indicator of whether the fan is turning or not. (for peace of mind)

With it setup this way, under normal driving conditions with the A/C on, it stays at 200*. It has climbed to 215 when hauling butt up a long hill, which I think is acceptable. It cools right back down to 200 when it's not being worked as hard.

What year Taurus you get that fan from?
I'm getting ready to swap in a new to me radiator and wouldn't mind changing out the fan too.
A few questions I have-
So you get rid of the primary fan that runs off the belt? I'm assuming you keep the secondary fan? And with the primary fan removed from the pulley, I would imagine you get a little more power?
Sorry for the twenty questions.

The 90-95 Taurus with the 3.8 has a 2 speed fan. This is the one you need. If there's not 3 wires, it's not the right fan.

I got rid of the belt driven fan, as well as the factory electric fan as it's part of the factory fan shroud.

I for sure feel more power, and will report back fuel mileage changes in a few days.

I need to use a different thermostat/controller so I can have it come on when the A/C is on, rather than just when the radiator temp hits the set temp. I went this route because it's what AAP had in stock, and I needed to make it automatic as quick as possible. I'll probably swap out the thermostat for a complete controller in the next couple days. My primary concern is building a shroud so that it pulls air across the whole condenser.

BTW, don't get it from Radiator Barn. If you'll look earlier in this build thread, I show why. It doesn't fit quite right....which has attributed to the overheat issues I've been dealing with.

Thanks for all the info, I'll be looking into doing that swap soon.
Mabe a dumb question. But what's the gain in having the two speeds?
I'll be keeping a watch on how you run the fan with the ac. Could you not use the thermostat and a bypass wire for the ac?

Just got a job offer making about double what I do now. Hopefully everything will pan out, and I can afford to make the Jeep more of a toy.


Let the modding begin!

Well, an update after running the T-fan for a while....

It cools great! I changed the wiring a bit, which I'll update with a diagram later on. I did SWITCH--THERMOSTAT PROBE--SPST RELAY--SPDT RELAY--FAN. The thermostat + first relay feed power to the SPDT relay, which normally sits with power to the low speed side of the fan. I used the factory E-Fan connector as the trigger for the SPDT relay, so that when the A/C is turned on, or the ECU sees 215*, it kicks the SPDT relay to send power to the high speed side of the fan. So far, I'm very pleased.


When at operating temp, the "extra space" on the passenger side of the radiator is barely warm. It's cool enough to touch, and keep your hand on it!

I went ahead and ordered this: http://www.amazon.com/gp/product/B00...ls_o00_s00_i00 18x26 cookie sheet to make a shroud out of. My radiator is 20x23, and my plan is to shave 1.5" from each end of the long side, to let it sit right down in between the tanks of the radiator. I'm going to use some sort of rubber weather strip to make a seal around it, and will seal off the moldings in the T-fan to cookie sheet mounting surface. This will allow maximum cooling for the radiator and the condenser, allowing for better A/C operation.

One major thing to note, is that I've gained about 3 miles per gallon from this mod. Very VERY happy about that.

Awesome man.
Please do post up a wiring diagram, I wouldn't mind coping you. If you dont mind
where did you get your relays from?

Will do. Feel free to copy. I'll post up details when I'm on a computer. I plan to try to do a full write up when I finish with the shroud.

here ya go Hope it makes sense.

Switch can shut down everything, when left on, the temp probe triggers power through the first relay, which sends power to terminal 87 on the second relay. When the factory e-fan is sent power by the computer, it triggers the second relay to switch the power output to 87a, which powers the high speed coil in the fan.
