Electric fans

Anyone run electric fans? I haven't seen any sign of it using the search feature.

I live in the great white upper peninsula of Michigan. I don't need a fan most of the time (can you say "cold"?). I have a high volume fan and heavy duty clutch due to the fact it's a plow truck (you want a fan roar, I've got a fan roar enough to make the grass lay down under my box).

Why? Keep the truck cool when I need it. Save gas by not having the clutch one run so much. Better throttle response. More horsepower. Be able to turn it off if I park my truck up to the headlights in the water again. Easier to change belts. Easier on the water pump. More room. Won't have to take off the radiator shroud when swapping motors.

Anyone have pictures? Do you run dual fans? If so, how big? Will a pair of 16" ones fit? Did you modify the shroud?

How well do they hold up to being submersed?

What are my plans? I want to run two of them off an adjustable switch. A single high-volume one isn't enough for me. I see they're getting inexpensive, Perma-cool ones in the Summit catalog are ~$90 each. That'd be around $250 for a pair of fans and a thermal switch. They'd probably pay for themselves in about a year if I can get 1mpg out of them. If my truck will warm up more quickly in the morning that'd be a bonus. Even 1 minute would make a world of difference.

I figure since I'm postponing a lift until spring I'd spend my money on something else (hey, I've already got all the bushings I need--I'm getting there). A Lock-right for the front axle is still in the near future but I want something to get my gas mileage past 10mpg.

Re: Electric fans

<font color="green"> I suggest doing a search on Colorado K5, this was a very popular subject a couple of months ago over there. </font color>

Re: Electric fans

Im runing a Ford Tbird V8 fan on the Blazer. Since this is my 1st post here Im not sure if theres a link to my pics in my sig. The Tbird fan is a 2 speed and I run it on low. I live in Fla and its a fairly brutal climate. I have only gotten above 160* maybe 3-4 times. And then its never been more that 170.

Shaggy was correct saying that a search on CK5 will give results. This was a hot topic off and on for the last yr or so.

Fan Pics Heres a link to the page of my pics the fan is on.

Re: Electric fans

I'm running a fan set up outa a 95(I think) Ford windstar mini van. Its a dual fan set up. Its pretty much a perfect fit on my 83. I know of a few bigblock chevelles(a 540) running around in texas that are bing kept cool buy it. I have the setup installed but havent really used it yet. I have set uo on a switch so I can turn it on or off at will or let it run of a thermometer. Beings its dual you can run them so one turns on at a specific time or temp and the other one comes on later. They are used in a daily driver mini van so they hold up to constant use and water and garbage splashed in there. I can snap pics and go into how I wired it if need be. Just leme know. I havent gotten a chance to see how it works since I havent swaped to the rat yet but leme say these suckes move some air [img]images/graemlins/cool.gif[/img]

Re: Electric fans

I'm running twin Perma-Cool 14" High Performance Electric Fans.

6000 est. cfm combined and they draw about 9.5 amps each

Wired them through a switch instead of a temp sender.

They seem to work well, but I haven't really had a chance to really try them out thoroughly yet [img]images/graemlins/wink.gif[/img]
