"Fan delete mod"

[dude8383]

I dont see how not having any fan is even feasible for a street car.

You are running the electric fan though right Matt?

My post was somewhat misleading :)

What I meant to say is that I want to run the stock AUX fan that is in front...without having to add an electric fan like a Spal or something.

If its a bad idea I'm open to suggestions because I'm still in the process of building.

Matt, where did you get all your parts for the conversion?

-Abe.

Through my work of course. :)

o0o0 too bad i already had that fan relay from jegs.... nice sig pic btw

I'm also running no fan with the 75* temp t-stat, Water Wetter and lower temp 80c e36 318i aux fan temp switch. I also used the stock aux fan without the a/c condensor. So I had to mount them using euro brackets.

Here is the post on how to mount stock aux fan with euro brackets:

Make sure you get the correct one for your plug type. See picture below.

Great mod!

btw - I have a set of euro brackets that I never used, so if anybody wants them please PM me. Just a few bucks plus shipping.

In my 318 rad i used the 75* t-stat, 80/88 switch and water wetter. Works great.

I have a nice Spal on the front of the radiator wired in to the stock wiring. It comes on by itself as needed. :)

what model fan do you have

[btec116]

Basic, but what temp does the standard T-stat switch at? Is this mod OK in summer traffic? Does anyone keep the original AC rad and electric fan with this combo?
Cheers.

so i was in traffic yesterday with 99deg heat wave, and with my electric fan on and the above mods, my car almost made it to the half-way mark.

[BeirBrennerE30]

Oh, I think the thermostat I got is the 75 degree also.

I thought you were running no fan at all. I tried that for about 2 weeks until I hot some traffic and almost had a nuclear melt down.

You need at least an Electric fan if you do this mod!

Nah, you have to have the elctric fan. It really barely ever comes on though.

Yea, but I think carbon fiber lets more heat through... :p

I have a 14" Spal with the Understeer kit. It pretty much has to kick on whenever I come to a stop, and the needle does creep up a bit.

Have not taken my e30 out into the heat wave yet...

Which Part # are you guys using for the 75 degree t-stat?

-Charlie

[clavinZERO]

Part numbers for the thermostats, via WorldPac:

71 degree: 11 53 1 466 174/71

75 degree: 11 53 1 466 174/75

80 degree: 11 53 1 713 040

Part numbers for the radiator-mounted thermo (temp) switches (aka Aux Fan Switch):

91/99 degree (stock on late model E30, 3-pole @ top-right of radiator): 61 31 1 378 073

80/88 degree (from E36/M42 motor apparently, same connector as late model E30): 61 31 8 361 787

SIDE NOTE:

I am doing similar mods this week, and I am putting a SPAL 16" Puller fan in on the engine side, mounted to the fan shroud somehow. I am going to wire it to the LOW speed power for the aux elctric fan, but I will bypass the resistor. I will let you guys know how she runs on some hot days. I have the 80 degree thermostat but the lower temp fan switch.

Matt and Cary... how have the HOT days been?

[nando]

if you are going to bypass the resistor, I would wire it so only the high speed comes on - I'm not sure the low speed circuit can handle the current draw. 13amps has been no problem for my high speed circuit though (I carry spare relays too).
