pics of electric fan intall
 

i've been a member for a while, and just though it's time that i contribute to the forum. hope this help out people who haven't done this conversion yet.

The fan is from a mid 80 pontiac fiero bought at pick and pull for $20, and the adjustable temp control unit was bought from auto zone for $15. seems to work pretty good. it's been in my car for about a month, and no problem so far.

Thanks for the pics, I'll be doing this mod soon. How have your temps changed since the install?

since the temp control is adjustable, i set the fan to go on at about half on the temp gauge. works great, the temp is always half way. but i'm planning to set the fan to come on at a third when summer hits.

Could you do a write up on how to wire it up? I suck at wiring!! Looks good!!

So is this more EFFECTIVE than the mechanical clutch-type fan?

I am thinkin about doin something similar when I get a Fluidyne for my nice FC.

here is a simple wiring diagram
 

that has to be one of the smartest installs ive seen done w/ electric fans..hooking the power up to the ignition...ingenious...Im practically on my way to the junk yard :)

THANKS!

what's the estimated hp 'gain' with this mod?

Time to go to the j-yard!!!! Thanks a lot!!!! Archive this damn post!!

and which pin on the green plug are you tapping?

damn thats pretty kewl, I see you have an upgraded radiator....is the install the same with the stock?

your lucky I have a 87 t2 and I have tried every high CFM fan out there and nothing will keep my temp down and I run evens coolent. The onlything that keeps it cool is the stock belt driven fan.

:confused: do you have to install the brake fluid bpttle next to the coils ?
:doh:
or was that added for looks :dunce:

vmb, dude the brake bottle give me like another 100 hp. lol:D :D

blackrx7, the install should be pretty much the same with the stock radiator.

It looks as though the plasic under tray is missing. You know, the big piece of plastic under the engine. I hear that thing helps airflow through the engine compartment. Going with that, wouldn't having one help with keeping your car running as cool as possible? Just wondering...

what size fuse did you need for that job?

i'm using a 20amp fuse

cool, ill probably be doing something really similar in the next month :)

Grinchy, The wire you are asking about is the one closest to the locking thing. And I think it's black/yellow. Hope this helps.

do you have a write-up on the brake fluid bottle mod??:D

cool dude i am doing the same thing rite now just wit a probe fan how did you rig fan to come on at difrent temps i just have a switch

the temp control unit that i bought had an adjustable switch that lets you control when you want the fan to come on.

grinchy, i tap it to the green plug. there is six hold on the green plug, it's the middle hold closest to the locking device on the green plug.

Sorry to bring this up, but i live in canada. I would love to have that temperature control unit. Would anyone be willing to ship it to me if i paypaled them the money?
Thanks

One more thing... I know you have a 5 blade fan... would a 7 blade fan be any different? pull more air? can it also be used?
Thanks

Thanks for directing me to the correct pin on the connector. Nice install and a great idea for here in the valley.

The mechanical fan is still better only if the fan clutch is good. Once the clutch starts slipping - this is the way to go.

I just finished my Electric Fan Install...I used a 96 Honda Civic A/C Fan..The fan that mounts to the Coils on Civic A/C..It works Fine..It is a smaller fan but it pulls alot of air...My next Task will be making a cold air intake for my 86 N/A...Details soon...

nice idea, a future mod for me, thanks . ex...

I have exact details and parts if you need them...Contact me at zaxfire@bellsouth.net Very Easy job...Not hard at all with the right parts..

DO NOT WIRE YOUR ELECTRIC FAN LIKE THIS!

That green plug is the diagnostic computer plug. The ignition feed that's been used has NOT been sized to handle the considerable current draw of an electric fan. If there is a short, all of the thin wire before that fuse (ie in the car's looms) will experience very high temps and could catch fire before the fuse blows! High-current items like fans, air horns, fog lights, etc should always be wired directly to the battery via a 30A relay, with the fuse mounted as close to the battery as possible. The relay can then be switched by the temp switch, which can by fed by any ignition source because of the low current draw.
Vulteiv, I suggest an immediate rewire!

I agree 100% with NZ...
Use a relay. Then, you could take advantage of the situation and wire up a switch so you have an option of whether you want the car to cool while it's off or not.

I live in Tucson, and it's gonna get real hot, real quick. I am gonna find myself a Fiero fan, but I need to see detailed pics of how the unit is mounted.

I did the electric fan mod too. Freaking easy. The only tricky part was that I had to hack some of the plastic battery holder base, only a small piece though. I bought this fan from summit racing. just go to www.summitracing.com and search for SUM-320716
It was like $100 bux shipped and pushes out 2300cfm and its reversible. The fan is really flat and it actually kept temperatures slightly cooler than stock mechanical fan. Mine was running all the time wired through a relay directly from the ignition.

Here is my pic of it:

hey trurx7 you r link doesnt work!

http://home.insightbb.com/~hellbird.79/fan.jpg

OOPS :P

Trurx7 you need a shroud around that fan. Once summer heat comes your gona have problems driving around town. IT'S GONA OVER HEAT!!!! (Speaking from experience)

I would do that. Too bad I sold that one already :) maybe for my T2

Where exactly do you hook up the fan to the ignition??

You don't! Read my post above. You hook up the fan relay to any switched power source. In the one above he's used the green diagnostic plug. Here's a diagram showing the only safe way to wire a fan up:

I relayed mine off the ignition. Generally electrical components last a little longer when they are not shut on/off constantly. Thats just my opinion though. I wouldnt even mess with the connector near the Igniion coil for diagnostic connections. I found my switched voltage near one of the relays behind the front bumper.

Follow the wiring diagram! Trust me!

ok i know absolutly dick about the electrical wiring, can you put it into plain english term and parts from radio shack and what not please??

i am selling my feiro fan for 70$ (canadian) if anyone wants it.. it pulls great just make sure u use a shroud...
i wired the fan right up to the battery.. the fan stayed on untill the engine was at a decent temp! it was sweet.. pm me if your intrested

You need a 30A automotive relay, a fuse holder with a 20A fuse, a fan thermoswitch and some suitably sized wire, all of which you can get from a decent auto parts store. Once you see the underside of the relay, my wiring diagram above will make perfect sense. :)

That's a bit backwards... :confused:

Shit NZCovertible! You suggested the 12v diagnostic plug as an Ignition source! Thank god no fire was started. I guess I should find another Ignition source to use for my Black Magic #150.

Before you go off at me, you should understand how these fans work. There’s a big difference between the ignition source used to switch the relay (low current) and the battery connection used to run the fan motor (high current).
If it bothers you, don’t use it. But it certainly won’t be causing any fires... :rolleyes:

NZConvertible///No offence! Just playing with you. :D

With my fan drawing 13.9 amps from the Battery, I would consider that to be way high. So what would be an alternative to use as an Ignition Source that will allow me to splice Into an existing wire within my 88 n/a Engine Bay?
