Ok who has converted to electric radiator fan, an can give me some information?

I would like to remove the original fan and replace it with a electric fan The car is just fine while driving but gets hot in stop and go traffic. I have had the radiator flow tested, replaced the thermostat, and flushed out the engin block.

I think I will have to change the generator to an alternator. The size of alternator would depend on the current the fans use. Is there an alternator that works best with electric radiator fans? Am I thinking straight or not?

Larry, we just had this discussion regarding electric fans, alternators, etc.. I just put a new tech tip in the Technical Resource Library under the Alternator & Generator section. Look for "Selecting The Right Tbird Alternator" in the Final Dress section. If you are going to add an electric fan, and necessary unit to control it, you may as well install a 130amp alternator or more, and be done with it. That way, if you add anything else electronically that is going to demand more power from that alternator, you will not have to worry about replacing one that has a much smaller amperage output. Read all the information on alternators in the TRL. As for the electric fan, Dave Dare and others can tell you what to look for, as he and others have electric fans on their cars.

Read through this article also.. http://www.squarebirds.org/vbulletin/showthread.php?t=18914

And this one also. Ryan got an electric fan setup from Cool Craft, I think it was..

yes, it was cool craft. really like. if you don't need the radiator they sell the fan and shroud custom made with a very simple relay temp unit controller.

I have been doing some more research for you. One person who has been down this road before, converting to an electric fan, is Greg ~ Dakota Boy. Here is what he put on his '58 Tbird with a 460 engine.

Late 90's Ford Contour V6 dual fan 24" x 16" x 3.5" w/shroud using a Flex-a-Lite 31163 electronic fan controller. This electric fan fits the OEM radiator perfectly.

New; from ebay for 100 bucks total; shipped to my front door.
Fan controller mounted in the rectangular hole at the bottom left corner.

Ray's comment:
Go down to my #1 post on this link to see what I found at our local Pick & Pull. As I recall, this is the fan that I sent to Dave who has this fan running on one of his Fords now.

Here are some pix of what Gregs fans look like, and in my thread, there are some pix of the fan I got off that Ford in the junk yard.

OEM fans work well, they are balanced and they last a very long time. I tried to get Ray Clark to put an electric fan on his 'bird at one time. He went to his local bone yard, found a Crown Vic and had them remove the alternator and fan. For some reason, Ray decided not to install them on his car so I bought both pieces from him and I mounted both on our '59 Galaxie Y-block.

The fan I'm using is one big fan in a molded shroud (like most of them are). The dual fans are ok as well... Ford turned one fan on all the time with the A/C compressor, and the other as a backup.

When you get the alternator with the fan you KNOW they are matched as the alternator is certainly large enough for the fan, even if the car sits like a taxi cab.

When I fitted the fan to my application I noticed there was a lot more room in front of the radiator so I spaced my radiator back toward the engine 1-1/2" and mounted the fan in front. This worked out great because the wires only needed to be reversed. These fan motors do not use a chassis ground because they are mounted in plastic. Another advantage is, the fan is not on the hot side of the radiator. It pushes colder air into the radiator and the fan motor never gets hot. Win, win. Works great.

I am using a temperature sensor mounted about half way down my radiator, just in case the coolant level dips. When the radiator gets hot the fan turns on. Just that simple. Just because the engine is up to temp does not mean the fan needs to run because wind removes heat from the radiator as the thermostat regulates the engine temp.

In Michigan winters, my cooling fan may not turn on for months. This is a tremendous gas savings and one of the reasons why modern cars get away with using smaller engines. Another feature new cars use is the WOT switch (wide open throttle). If you floor the gas pedal, this switch shuts off your A/C, alternator, cooling fan, etc., to deliver maximum HP to the wheels until you lift your foot after you get off the tracks. - Dave

I just put this information in the TRL under Fans, Fan Shrouds & Electric Fans... I figured it would be good to have it there, plus, whatever else is added to this thread.

What year of Ford Contour is the correct size...i.e. 24" x 18"
I see sizes vary.....

I went with one for a 1998 Ford Contour 2.5l V6. Rockauto's part number for it was Dorman 620104.

Since photobucket has changed how they work, I don't know how to share photos well anymore...

You can see how I mounted it in one of the photos.

But lets try this method.

Bryan, these are fabulous pictures and great information for every Squarebirder. Can I post them on our site?

BTW, I love the two-fan system because most of the time one small fan will do the trick. In extreme heat, both fans. AND, if one happens to fail there is a backup. - Dave

Yes you can post them. FWIW, this setup is on a 390 with a 671 blower, so far I've had zero heating issues with her, but I have not run her during the summer yet.

Yeah, I didn't think to post the controller I also got for them. It's a thermo controller with a temp sensor mounted into the radiator that is supposed to be designed for dual fans.

They are actually MIG welded on there, if no one will make fun of my welding, I can post another photo that shows it better......

My radiator is original to the car. But we did re-core it with a larger high performance core, removed the surge tank, and am using a more typical overflow tank on the fender.

Cheers

necessity is the mother of invention, What control unit did you use, looking at a few in the 50.00 range...

I used the Hayden one for dual fans, #3654. I think I paid just under $50 for it on Amazon.

Here's a link to my photos of ole "BigBird" as my kids call her...

For the fan mounts I used flat stock with a bolt welded to it through a hole I drilled. Smoothed the backside so it wouldn't damage the vanes.

Just got everything for the elect fan install...I have the original 3 pulley on the water pump . looks like not enough clearnce for the electric fan unit .. did you ust the orginal water pump or an after market pulley set up....did you have to remove the hood?

Opps, forgot to mention, I am running an aftermarket alum water pump, no surge tank and yes, I had the hood off while I was replacing it all. Never thought about the hood being an issue, sorry.

And I'm running a two groove pulley.

I love this setup:

http://www.squarebirds.org/vbulletin/attachment.php?attachmentid=11125&d=1434088429

After taking the old fan and spacer off there is plenty of room for a fan. Notice the foam between radiator and fan shroud. I also love that the fan controller is mounted in the lower corner of the radiator. It's a mistake to put it high, in case the water level in your radiator drops.

The fan cools the radiator. Engine temp has nothing to do with the fan. In Michigan winters, my cooling fan goes months without turning on. - Dave

Do you have the water pump and pulley set model numbers and source of purchase ?

For the Hayden controller...has 2 hi (BLUE) & 2 low (ORANGE)
wires do 1 of each go to the positive for each fan ?

What distributor and coil setup are you using ?

That was an Accel distributor and coil in the photo. Engine is a 460. Since this photo was taken, I have changed to an MSD distributor and MSD coil.

My Summit Racing list shows it was a Tuff Stuff Pump TFF-1421. The pulley I got from a local FE guy that seemed to know what I needed to line everything up correctly. I also got a three groove crank pulley from him at the same time, don't remember what it was from.

Summit also showed a March 2 groove pulley, but I only kept it in my wish list since I found one locally that did the trick.
