Electric Fan

Found this on Amazon while looking for something else the other day.

I've been thinking about electric fan ever since I took mine off the water pump. I'm doing alot more in town driving now, so I reluctantly put it back on.

Thoughts?

I would think this would be a better choice. But maybe it won't fit, I just like it because it has more CFM

i would think a 2 fan setup would be better. is there anywhere that sells electical kits for em so they only go on when the coolant is x degrees hot?

That's what this controller unit is for.

FWIW, I would just stick with the stock fan setup for a couple reasons. One is that these truck don't lack for torque, so driving the fan isn't a big deal to our motors. The other, and this is just me, but I don't want to compromise the durability of my truck in the name of such a few horses. Sure the stock fan is a bit noisy at times, but it works and I don't have to worry about the controller not cycling the fans on correctly, or the motor on the fan going out and leaving me stranded someplace. That's just my personal preference, though.

I always thought highly of flex-a-lite until the fan kit for my off-road ranger started taking a crap. No mud, all rock crawling and the wires right out of the electric motor started melting together.

It cycled on and off great. Just not happy with the wiring issue.

Just find a ford taurus fan and throw it on there. Those fans move a ton of air

if you tow anything at all or live in 100*+ summer conditions, an electric fan isnt adequate. i did a taurus 2 speed e fan swap and took it off after a week. just didnt do the job

I'm on my phone so can't look at the specs. If I remember right the elec. fan will move about 1500CFM. I don't know about our fan but I did read that the 6.0 fan is supposed to move about 10K CFM. I can't imagine our trucks are much different 10% of stock? Don't think that's going to cut it. I don't tow anything and live in a cooler state (or so I thought until last week). I have had the fan off for a couple years and haven't had any trouble ubtil recently. I was driving about 90% highway so getting plenty of airflow. Lately I've been doing alot more in town driving so I put it back in. I think the clutch is messed up though. Seems like the fan is on almost all the time.

forget that.
try one of these instead.don't forget you'll want to find the two wire plug,pigtails:
http://cgi.ebay.com/ebaymotors/95-98...Q5fAccessories
(fabrication of another slimmer motor in place of the large extruding one, may be required for your engine.alternatively,the fans can be installed upside down as well,so the larger fan motor has more open room.)

i had a 2nd fan installed, and the alternator wouldnt keep up with it. even with 2 of them in summer a/c on and towing heavy loads as i do everyday, they couldnt keep the truck under 230*F or so.

but just for the sake of asking, why would you want to spend over $300 on an electric fan unit that gives you no additional benefit when the stock fan does more than a good job? it is a diesel truck, not a racecar so is the unnoticeable gain in power really worth over $300 bucks?

ive installed numerous electric fans and have just come to the conclusion that with a heavy duty vehicle such as a diesel truck, electric fans just dont do a comparable job to a clutch fan for cooling in hot weather with a load. sure they work great for 4 cylinders and racecars and whatnot, but not for trucks made for work purposes.

just for some more perspective.... i run a taurus fan on my bronco rockcrawler. there is rarely a time i get up to speed to cool the engine so the fan does all the work. we go wheelin in some pretty hot weather and the taurus fan is more than enough to keep the motor cool. no i dont have a built motor and no i dont tow with it, but i do beat on it hard. all i do in it is low ground speed, high revving/tire speed, crawling.

my question to you towsrus is how sealed was your shroud? if it does no seal well then of course it will be like trying to cool a screen porch with a window unit.

i have messed with a lot of different combos of fans, radiators, and controllers and am very pleased so far with this one. i have $100 in my setup using this controller http://www.flex-a-lite.com/auto/html/vsc.html

i am not condoning one method or another, i like the idea of less complexity of the clutch fan but i also like the idea of having control of the elec unit. everything has its advantages and disadvantages.

I had a custom shroud i built out of 16gauge sheet metal and it was pretty well sealed. in summer we get 115* out and thats when i would start getting problems especially hauling loads up hills. like i said before i dont disapprove electric fans. i have them on m ls1 1954 chevy project and it works great. its just a little different with the diesel cooling systems i tend to believe. the strain on the alternator is another problem ive hit on these powerstrokes. sure you could run a 2nd alternator ambulance setup for most of the trucks, but i dont have that option as i have to run an engine driven hydraulic pump for my tow beds.

At what temp do gasser electric fans cycle? I've heard they come on as low as 170 (off @ ?), but since our trucks are supposed to run 205 t-stats what temp "should" the electric (or mechanical fan clutch) kick in/off. Been thinking of this mod, already hav a few electric fans from other projects over the years.

i do not run a t-stat in my bronco. due to the elec fan controller there is no need. it does not see any kind of speed, certainly not highway speed so its not like i have a hard time warming up. now i know this is not typical but it works great for me.

what i would probably do on a PSD is keep the stock t-stat intact and run a controller similar to the one i have in the bronco.
