I have compiled all the parts to convert my 99 3.0 to utilize an electric fan. According to my Chilton's manual, I need special wrenches to get the old fan off, but I think I can handle that. I've figured out all the detalis of the installation. What I'm not certain of is what all needs to come off with the old fan. Any ideas?

 

When i worked at te Ford dealer i pulled the fan off a Ranger and the was the only time. Another mechanic pulled out a long combo wrench that fit the nut thats on the fan shaft and he told me it's left handed treads and to tap the box end of the wrench to spin the shaft free from the mater pump. If i remember right the pulley is still attached even if you pull the fan.
I was considering putting on a black magic fan kit myself, i would like to know if anybody has one and likes it. and if they gained anything like gas milege or power, besides the odvious, getting rid of the fan making noise everytime you take off from a light.

 

I used the Flex-A-Lite fan on my 91 3.0 and I really like it, probably the best power increase I have done yet. Gas mileage increased about 1 mpg. I had to use a strap wrench on the pulley and a big crescent on the nut to remove old fan, not sure how newer models come off. Someone needs to tell Ford to put a factory electric fan on these motors, I believe the same motor in the cars have them, thats one reason that Taurus beside you will probably blow your doors off.

 

Before I will part with $300 to convert to electric fan, I will want to know what gain I will receive. I have been unable to search out any data on how much HP that fan pulls. Anybody know?

I'm seriously thinking about doing this mod but i want to know if it keeps your truck as cool as the factory fan. My truck never leaves the normal mark even towing a trailer up a grade with the A/C on and being 120 degrees outside. Will i get the same if not better performance with the electric???

 

jimw411 can't tell you about towing, never towed anything with mine and it hasn't reached 120 degrees here in a few years. The way my fan is hooked up it runs when the ac is on, it also has an adjustable thermostat. You will get better performance with an electric fan.

 

Jim I asked the same question over at RPS. But they were talking about Electric fan AND underdrive pulley conversion.

My question was

"I still have some nagging doubts/questions. I live in the Southern Calif desert where the temperature routinely hits 110 to 115 in the summertime. If I install the u/d pulley I assume it will slow down things like my water pump and a/c compressor. How will that effect my engine cooling and in cab a/c?
I assume if I install an electric fan at the same time that will take care of any cooling problems, but what about my in cab a/c? Any advice or firsthand knowledge on these questions would be greatly appreciated.

One of the answers I got was

"There are many people here who have an UDP and live in Texas, Florida, and even SoCal and don't experience any issues with their A/C. Just remember that most of your accessories are designed to work at full capacity on about 1000-1500 rpms or less. I'll be honest, I have seen the actual numbers and believe they are even less, but don't have them in front of me at the moment.

This means the only time you MIGHT have any issues is at idle. The ONLY issue I've experienced is with the alternator. At night when I have the lights, stereo, A/C all on and am setting at a stop light, I will experience some dimming of the headlights. Not enough to matter and I've not noticed any appreciable decrease in the A/C cooling.

Some people have replaced their alternator, especially if they are pumping a huge wattage stereo, with an explorer alt. The Ranger alt is about 95 amps and the explorer one is 200 amps and, from what I've read, a pretty easy bolt on."

If you're interested, and want to read the entire tread, it's at.



Hope that helps.

 

My fan was designed for flat head ford hot rods, it's a 3300 cfm fan, from what I was told at the ford dealership, the stock fan only blows 1600 cfm. So I'm pretty sure it'll keep my truck cool. The best part is, I got it for $95 bucks from a guy down the street who decided to go with a dual fan set up on his '40. I am seriously considering the alternater swap, considering that the fan is so big. I don't run my A/C much......I prefer windows down when possible. I live in the mountains, too, so the temperatures never get too high.
