There has been a lot of talk about the Ford Taurus E-fan being a nice fit for our
1st gens, but nobody has said what year. I think it may be a 93 Taurus, but I'm not sure. Can someone tell me? Also, is there anything else I need to get from the Taurus to make the fan come on and off they way it should?

Thanks,

Mike

Second generation taurus, 92 through 95. 3800 engine.

Get the whole fan, up to the plug. Get the plug, and the three wires AFTER IT.

Do not just unplug it and walk away, it will be harder this way. Get about 6 inches of wire after the plug, snip it and go.

Test the wires. You should have 3. One ground, one high speed, one low speed. You will need the low speed since it draws less and flows more than stock.

Test the wire by grounding the black wire and applying power to one of the other wires. 2 colors, but the low speed color escapes me right now.

The low speed wire you connect to a 30amp relay. The ground wire to a ground. The high speed you just leave alone.

Hook the power to the relay directly from the battery to the relay power. Ground to a ground. You get the signal wire from the relay to the positive side of the coil, that way when you turn the ignition on the fan comes on.

Voila, electric fan.

You can get fancy by adding a thermostat, switch, etc.


Using no thermostat and hooking it like the above worked great for me and was trouble free for months on end. Now I have it hooked to a switch in the dash to where I have it off when I start the car until it is warm, and can turn it off on the highway.

Thanks man! I really do want it wired up to a thermo switch. Is the thermostat controlled or tied into the ECU?

No ECU. You can actually wire it in through the sensor on the back of the water pump. It will turn it on at about 150 and not turn it off until the car cools lower than that, ie when the car has been off for a while.

You can although get some 2 or 2.5" pipe and weld in a nut to hold a thermo sensor in place and put it on the upper rad hose. That way you have a thermo sensor and it will turn on/off at whatever you set it at.

I tend to keep things cheap (penny pincher here) and went with the signal from the coils. Only costed me 20$ total, that includes the fan. The switch I used later on I found leftover from other projects.

The thermostats on both my fans have a probe that goes in the fins of the radiator. I have it set to kick on aound 185 and off at 180.
Jeezus you sure about that 150 figure? Thats much to cold, the engines thermostat opens at 180....

The 12a tstat starts to open at 180 F and is fully open at 203 F. Jeezus is talking about the thermo switch on the base of the tstat housing. Its spec'ed to break the connection at 159 F +- 11 F. He's just saying you can use that as a sort of thermo switch to control the fan. It would make the fan basically run all the time. You need a relay to implement it correctly.

I prefer the use of the top gear switch on the tranny to turn off the fan during highway cruising in 4th or 5th Write up coming on that one. Wasn't there a thread like this a couple of days ago?

Hey Tim,

I think that switch setup is only on the SAs. From the FSM, it looks like the SAs have a 'top switch' (4th gear) and 'over top'/'overdrive' (5th gear). For the FBs, I'm almost positive that there is only the 'over top' (5th gear) switch.

does anyone know the tread on the thermo switch for the choke. I'm not using the choke so I was looking at getting one of those switches to run there.

Not surprised Kent. I'm a noob on FBs sometimes.
