Engine Fan Delete

[christophbmw]

check out: www.autoloc.com they have some pretty sweet cooling stuff.

If I wire the stock "pusher" fan to a switch to turn on/off, will it be enough without the engine fan to keep it cool if I'm sitting still? I'm contemplating doing this.

[X2theZ3]

Is that ultra thin one adequate for daily driving?

don't know - the list CFM's I think - Most of those fans are for street rods - BIG american blocks...I think they can handle a m20 at idle during the summer.

George,

Are you using an electric fan for you m30 swap? I'm still deciding on doing the electric thing or stock fan?

I think it would be, the stock M20 clutch fan isn't going to be moving that much air at 650rpm anyway. $75 plus $20 for a mounting kit sounds like a good deal.

My A/C compressor is dead, took out the mechanical fan, cut the compressor belt, and just let the auxiliary fan do the cooling. Been working fine for about 2 years now, plus I can turn it off when I'm on the interstate.

So you use the A/C button to "flip" the aux fan on and off?

Yes, you can only use the m30's crank/normal fan in "engine position 3" The puts the motor really far back - almost sitting on the firewall, and expect to have to pound out some clearence on the tranny tunnel.

"Position 1" has no room for a raiator in it's normal place(engine TOO far forward) - a custom radiator has to be made to fit behind the grill..

Position 2 is where it's at - 3 is just too tight for comfort.

go with a flex-a-lite black magic. i think it pulls more CFM than most other fans and it looks the best and is pretty thin. Also, it fits my radiator very well. i just wired it straight to my battery and hooked up a toggle switch right next to the shifter in the console. the problem there is that you have to remember to turn it on/off. lets the car warm up a bit quicker in the winter though. (for those of us that have snow)

Yup. The only problem with this that I have is that the idle raises maybe 50-100 RPMs to account for the added load the compressor would normally add. I tried unplugging different wires from the back of the switch, but none of them fixed the problem.

While were on the subject what is a good replacement radiator that is thinner than the stock unit and cools at least as good?

My AC is gone, when i press teh switch it does nothing at all. My Gf's dads e30 a/c also deleted but his raises idle...duno what thats all about

[parkerbink]

Beej are you using the ac fan in it's stock position in front of the radiator, or did you move it?

I would love to do this if I can just remove the fan & clutch.

[Skafrog]

Wow, this is an old ass thread.
I removed all my A/C components, I took everything out, the ziptied the fan on the front side of the radiator, and hooked the A/C fan back up to its stock harness.
Works great.

[parkerbink]

So, in order to use the air conditioner's electric fan it is necessary to move it to the radiator side?

Thanks
