Converting to an electric fan

myol blue4x4 -> Converting to an electric fan (6/5/2008 8:35:55 AM)
Well I have been pondering about converting the mechanical radiator fan to electric. I read a few posts about it on here and they wernt that informative but I did come up with somethings online. They basically had it hooked up to a relay, it consisted of ignition wire to relay, ground to relay, positive to relay and then to fans, and finally grounding the fans. I dont know if any of this makes sence but I think it should work fine but I came across something that stated you needed to have the fan run faster when you turn your AC on. So, If thats the case would have to wire it up differently, if anyone has any comments your help is appriciated, thanks.

Keep you stock clutch fan, the electric fan will not move as much air. I have done this on a Dakota I had a few years ago it was good in the cold months but ran hot in the summer. I put the stock clutch fan back on.

If you put an efan on it, then I would put 2. One that turns on when it reaches a certain temp and one that turns on when your ac is on. For the 1st one, I would put a temp probe in the radiator and wire it up to that so it kicks in when it reaches a predetermined temp. As for the one that turns on with the ac, just ground it and run a relay that taps into the ac clutch circuit.

Look into the ford taurus e-fan. Best bang for you buck. Here is some good info e-fan and here is a good write up- http://s-seriesforum.com/how-to-efan.html Also for the 2 comments posted previous. This fan will def. move more air than you manual fan. Also since this is a 2 speed fan you don''t need 2 fans. I was able to get my fan from the junkyard for either $25 or $30 bucks(dont remember). Then probably another $30-$40 for the temp switch. relays, wiring.... Well worth it in my opinion.

I did it in mine and seen zero improvement in anything. Just a big waste of $$$ in my truck cools great, but no power or mpg gained with it.

Blazin_Jason -> RE: Converting to an electric fan (6/13/2008 6:06:37 PM)
What fan setup Clay? I still want to convert my jimmy to electric fan. Should allow the engine to warm up a little faster in winter, cool better and more consistent in summer. If I can get any more free HP or mileage that would be a bonus.

95_4door -> RE: Converting to an electric fan (6/13/2008 7:26:19 PM)
I forget about the 2 speed fans. But 2 fans would probably move more air than a single two speed.

myol blue4x4 -> RE: Converting to an electric fan (6/13/2008 8:00:25 PM)
Well thanks for the opinions and info. Im kind of stumped weather to go through and do it though. Im not looking for big improvements, just a setup possibly more efficient but, like jason said hp and mpg increases is a plus. So is it worth it to go through and do it or should the stock fan and clutch stay on??

swartlkk -> RE: Converting to an electric fan (6/13/2008 8:06:43 PM)
I have to ask... Why does everyone think that an electric fan is more efficient?

myol blue4x4 -> RE: Converting to an electric fan (6/13/2008 8:18:44 PM)
Well I came up with the thought of doing it through others opinions and so forth. So really I dont have a specific opinion towards e-fans and thats why I posted on this subject. But swartlkk, what would you say about electric fans because I dont want to waste time and money if the stock fan is more efficent.

The Slacker -> RE: Converting to an electric fan (6/20/2008 8:37:07 PM)
Stick with a clutch fan! There are few reasons why you will ever need to convert to electric. Maybe if you run through high water and need to shut it off or if you overheat at idle. Clutch fans will reduce energy consumption at operating temperature so I woulnd''t worry about any "performance benefits"

djdrew010 -> RE: Converting to an electric fan (6/20/2008 11:35:04 PM)
the more electronics the more problems you have to worry about. and if it takes a crap on you while you are driving your sol.

The A Team -> RE: Converting to an electric fan (6/29/2008 7:14:46 PM)
Ya like i said i put one in my truck, basicly just wasted $260. No gains in any areas, power or millage, no probloems with it either. The thing is the stock fan works just as good, and doesnt cost you anything. lol Bottom line its a pointless upgrade.

ChevyBoy413 -> RE: Converting to an electric fan (8/4/2008 9:37:19 PM)
ok first off these guys have NO clue what there talkin bout...i have 2 10" fans on my 97...works great!...hook it up to a 25-30 amp switch with an in-line fuse run it to the inside of the truck and good to go...u gain power and about 2 mpg...the reason u gain power is ur removing that heavy ass fan and clutch...therefore taking stress off the engine making it faster...common ****ing sense!....second off if ur too worried about things just go to summit and get a flex-a-lite fan...its a very light fan that will fit ur stock clutch...and with that being said...ur good to go...have fun!

swartlkk -> RE: Converting to an electric fan (8/5/2008 3:06:07 AM)
Common sense eh. Well good for you! The stock plastic fan and clutch don''t weigh much at all so don''t know what tree you are barking up there. And I do know more than a thing or two about fan setups.[;)]

quote: ORIGINAL: ChevyBoy413 the reason u gain power is ur removing that heavy ass fan and clutch...therefore taking stress off the engine making it faster...common ****ing sense!... Stock fan: Mechanical energy -> mechanical energy e-fan: Mechanical energy -> electrical energy -> mechanical energy Every time energy is converted, you lose efficiency. If you can find a fan that''s more than 100% efficient in order to cover the conversion losses, then you might do alright. I wish you luck in finding a fan that''s more than 100% efficient...

Blazin_Jason -> RE: Converting to an electric fan (8/5/2008 4:03:34 PM)
You engineering students think you''re so smart. I''m still gonna do an efan swap though.

swartlkk -> RE: Converting to an electric fan (8/5/2008 5:36:31 PM)
With a v8 swap, you have very few other choices.

Blazin_Jason -> RE: Converting to an electric fan (8/5/2008 5:49:06 PM)
I already have a taurus fan on the v8, but I want one for my 4.3. That was it''s just one less thing to do when I v8 it, hah.

Taymacjack -> RE: Converting to an electric fan (8/6/2008 4:35:52 AM)
Go efan, that way it doesnt sound like a F-16 taking off when you use your AC...
