Topic: Electric Fan Installation

Can someone tell me where I can find a diagram to wire my Taurus fan On my 98 2.5 L TJ
I want to have a temp switch, a relay and an on, off, on switch.
And of course fuses.
I have done several wiring projects in the past, wired my VW dune buggy to make it street legal
from scratch.
Thanks,
Vance

this is the way is supposed to be wired (i got this image from here which is a good read http://www.aaroncake.net/rx-7/efaninstall.htm)

but make sure to match your amp draw for the fuses, relay and wires

you should have a look here as well http://www.offroaders.com/info/tech-corner/reading/automotive-wiring.htm

Is the fan suppose to blow towards the radiator or pull from it?
The Ford Taurus fan I found is only a single speed.
Will that be OK?
I got a Ford Escort fan, it pulls instead of blow.
but it's a 2 speed.
Thanks,
Vance

A single speed Taurus fan is from the smaller engined car. It might work but really, if you're going to go through the trouble then you might as well do it right.  Especially, if the fans cost the same.  It needs to be from a 3.8L and only the 3.8L.  You can check the Sable as well.  The fan will be a puller.

Get the 2spd from the 3.8L Fords, the shroud fits the Wrangler radiators perfectly.  They are all puller fans, not many OEM pushers out there.

a puller will be installed between the rad and the motor (on the motor side of the rad). a pusher will need to be installed in front of the rad behind the grill - the reason is to not fight the natural airflow you have when the vehicle is moving (as well as not pulling/pushing the hot air from the engine bay but that is a the secondary reason for not doing this) - so keep in mind that the airflow (natural or forced using the e-fan or stock fan) _needs_ to be
1. thru the grill, thru the rad, and thru the fan shroud (with a puller fan)
or
2. thru the grill, thru the fan and fan shroud, and thru the rad (with a pusher fan)

Delta Current Control has a new controller out specifically for the Ford two speed fans. Its called the 2SP, has two 60 amp relays and sells for $69.95.

by the looks of the pic in there it seems that it includes also the wiring harness and the temp sensor so that is a great price

Also I just realized the power steering and overflow reservoirs are mounted on the stock fan shroud.
Do you guys have any good ideas, pictures on how you're mounting them?
Thanks,

The only thing it lacks is the PWM which is Pulse-Wave Modulation.  That's what gives the variable speed of the fan.  Still, for most people, that won't matter as all they want is the fan to turn on and off.  The PWM is jsut a added plus.  Wish they could lower the cost a bit though.  Seems the only two major players are SPAL and Delta.

You have a TJ so you're going to have to relocate them.

Yep, I was hoping I could see some pictures or get some ideas on how
guys did it?

Flex-a-lite makes a bracket to relocate both the PS and Coolant reservoirs.

I got it figured out how to put a switch in to turn the fan on manually.
I have the switched power (in the diagram) going into an on off on toggle switch.
Everything else I have wired just like the diagram.
I have the power going from the toggle switch to the fan.
I want to use another relay so I don't overload the toggle switch.
How do I wire the relay in?
before or after the toggle switch?
Thanks,
Vance

If I understand you correctly, you are trying to wire your fan up so that the low speed is setup like the diagram, but with the option of turning on the high speed manually with the other position on your switch.
If that is what you are trying to do, you need to have a second relay activated by the switch allowing current to flow from the battery through the relay to the high speed wire for the fan. The power should not be going from the battery through the switch to the fan. Wire the second relay the same as the diagram, but with out the thermostat. The #86 on the relay will just go to ground. Provided you have wired your switch correctly, when you flip your switch from the low speed position to the high speed position the low speed will be de-activated and in the off position both are off.
