My Electric Fan Swap

The electric fan died on my Jeep a couple of weeks ago.. I plan to replace it with a Ford Contour fan that came out of a 1996 model. Once ordered, it came to my attention that these fans new or used rarely come with any wiring.

So here goes... Here is the old fan that came with my Jeep. Might be a Taurus. I do not know.

Here is my new (used) Contour fan minus the wiring.
Note the factory plug that came with it, Hackfab says these are pricey!Look at all that room!Here is a test fit, looks good. I do not even know if the radiator came out of a CJ or something else.

I will keep you guys posted on the progress.

I contacted the salvage yard who sent me the fan, and explained to them that I also needed to wiring for the fan(s) . I had mentioned that to them when I initially placed the order.

They seemed helpful and said they would try to find me a harness for the two blower motors.

If you can't find the connectors, let me know and I'll see how much they are at cost.

Your best off finding a used harness as it will have both connectors for the fans as well as the resistor. It keeps you from having to connect and solder a bunch of 10 gauge wires too. I'll see if I can find the connector part numbers and get the prices tomorrow.

I really do not know... I plan on ordering a VSC once the wiring/plug issue is taken care of.

What is the benefit of having the fans run after the engine is turned off? Anyone know?

it will help cool the radiator after the jeep is off but the thing is it wont circulate the antifreeze so it wont do alot of good. It will help cool the surface temps down but its also drawing on the batt when the engine isnt running. I have mine to where low speed kicks on only when key on, high speed kicks if it needs to. I have two switches in the cab one that kills low speed when in water crossings and one that will force high speed on (without t-stat calling for it). I have a dummy override in the system that will allow high to kick on when key onregardless of if low speed is shut down (I can be forgetfull). I didnt use a controller I just wired it all off the facotory wiring plus the switching.

If you could that would be great. I think others may be thinking of doing the swap.
I'm thinking of it, I'll have to see how mine performs in the summer heat.

Sorry for the Hijack

You won't need the resistor if you wire the two fans together and use a Variable Speed Controller to run the fans.

These are the pigtails: http://www.rockauto.com/catalog/rafr...&parttype=2556 You may be able to acquire them from an alternative source. But based on those prices, it'll run ya around $40 for two shipped.

The plastic housings for the plugs are available from Ford, but they do not include the crimp on terminals for the wire. The part is a Delphi (AC Delco) item, but they aren't your traditional spade connectors. I searched (internet) in vain for a source and could not locate one.
