I have done several fan installs in jeeps and have always gone with contour dual fans because they fit a CJ7 or Grand Wagoneer radiator almost perfectly. I am not a fan of strapping the fans through he radiator fins because, in my experience, the fins always start to get damaged from the weight after prolonged use. What I would do with the old jeeps is take an old busted rad and cut the mount tabs off and then attach them to the contour fan and it would bolt up very nice.

I went to do some junkyard diving last weekend in hopes of trying a contour fan on my 06 fiddy but what I found was that paticular model fan was about 6 inches shorter than the fin surface on the truck's radiator. After some peeking under hoods I came across a windstar and took some measurements.

The fan from the windstar is so close to the dimensions of my radiators preexisting mounts that it is painful. If you bolt the upper mount on the passenger side of the radiator up the mount tab on the dirver's side is literally like an inch shy of the drivers side mount and about a half inch low enough that if you exented it someone it would sit on the rad at an angle.

Im not quite yet but I picked up some angle brackets from lowes and cut the upper and lower mount tabs off the driver's side then mounted the metal brackets in the appropriate spots. I left the original upper tab on the passenger side but I was not able to come up with a good solution for the lower passenger side bracket because that side of the fan does not have the same lip as the drivers side so I will have to be slightly more creative with the bracket.

The unit doesnt perfectly sit against the rad but it still pulls hard enough that you can stick a dvd case (had one sitting on the floor of the truck) and it won't hold it in place but it will very slowly slide down the radiator and the ac condensor can hold up a few sheets of paper. I honestly never testd how strong the air pullwas with the original fan so I don't have a comparison.

All I have left is to get my Flexalite variable speed controller from flexalite and figure out a reliable way of mounting that lower pass side and she will be back on the road. I am also toying with the idea of maybe getting some heavier rubber sheets and trying to maybe cut them and attach them to the shroud of the windstar fan to maybe help direct the flow a little better but I want to see how it does in the Alabama heat as is before I go through the trouble.


I need to pick up appropriately sized bolts

 

Nice job.....this mod is looking good so far

 

same fans i used on my install. i cut both bottom mounts off of mine. i didnt have to cut the top mounting tabs tho and used a U shaped bracket to hold it on the passenger side since i mounted it directly to the drivers side.

im also surprised ford didnt use these fans on earlier models. they cover almost all of the radiator.

 

I am assuming you did the windstar fan in your 01 f150 in your sig? Have you had any problems with it at all?

How did you control yours. I like those flexalite variable controllers because they dont use one of those cheap relays like the controllers from the parts store and it also cuts on the power at 60% of its amperage when it activates the fan and gradually increases the draw to 100% as needed. They also have provision built in to add a switch to the ciruit if you want to be able to shut off the fan.

I am still thinking of just going to a JY and grabbing some of that thick rubber they use under bumpers and such to extend the shroud to the rad fins.

 

thanks I really wanted to make this look like it was as stock as possible.

 

yes, its on my truck in my sig. ive only been running it for 3 weeks but its working fine so far. im using a MAD controller from madenterprise.com.

my fans sit flush with my radiator. in dont have any gaps.

 

ive routed the wires better since these pics. but it shows how close mine is the radiator.

 

Hey OP - Welcome!

Just fer reference - here's a Benchmark install:

https://www.f150online.com/forums/ar...150-4-2-a.html

BTW - those Windstar fans look kinda small to me (designed to cool a v6 minivan not a V8, 6,000+lb pickup) - yer planning to run 'em both all the time, right?

I hope they can keep up. If not you can always dumspter-dive for a Mark VIII efan, OR, spring for new 2010 F150 OEM efans.

BTW #2 - not a fan of Flexalite controllers - look at the controller in the link above - top-shelf stuff.

Ensure wiring practices are exemplary.

Good luck.

 

The larger low speed fan is 16" and the smaller high speed fan is 14".

i havent had my high speed kick on yet, but i also dont live in the heat that the OP has.

 

That mark fan install you did is pretty nice and well done. I couldnt find a part number for the '10 fans or even a picture of one. I was begining to think they didn't exist.

As far as cooling power I these are a little larger than the contour fan and that contour fan was able to cool a 88 Jeep Grand Wagoneer with an old school AMC 360 (5.9l). I looked it up on the web and each of these windstar fans individually pull about 2100 to 2200 cfm a piece so combined your looking at close to 4400 CFM. Those taurus/mark fans push about 4500 cfm on the high setting and 3500 on the low setting. Theoretically the mark and the windstar fan push the same amount of air. I didn't go withthe fan you used because I am not a firm believer that there is a heck of alot of performance gains from these swaps. I wanted to have decent access to the from of the engine for maintance. The windstar fan fits really tight to the rad and gives you an insane amount of room to get to the belts or the oil filter etc.

 

The wiring harness on the one I pulled at the junkyard had the fans wired to come on at the same time from the factory. I am going to wire them that way with my controller.

I didn't realize that one fan was a high speed and the other was a low speed. I am glad you mentioned that because I was curious why one is rated for about 100 less cfm. I also thought it was odd that one seemed to pull harder when I tested it. I thought maybe I had a bad unit. I am glad you cleared that up!

 

Oye.

Is there a baffle between the two fans? If not the stonger one will 'rob' airflow from the weaker one.

I alway thought the smaller fan was triggered by A/C operation and/or extra cooling requirements as sensed by the factory PCM...

LOL - that was not me... The was Mr. Fairlaner.

Here's some 2010 fan info ( they're be part numbers, etc in there): https://www.f150online.com/forums/4853280-post26.html

And here's some additional efan info ( links within links, lol):

so you have the whole wiring harness? do you know what temp they are set to come on from the factory? i just had the positive and neg. wires on the fans to work with.

i have my low fan set to kick on at 196 and the high speed fan to kick on at 205. but im running a 180 T-stat too.

 

no, there isnt a baffle.


i have my second fan set that way.
