Electric Fan Convertion

Ok i wanna get rid of my mechanical fan and clutch, and put an electric fan instead, now ill im concerned is where do i do the wiring, and what do i connect it too, and what parts i need to buy, to make it happen
also i dont want to have to turn on the fan every time it gets a little high, i live in florida,and i need the car rather cool,

Please help with the wiring

there is a company that sells a external thermostat i have one but ill find out what the name was... .... when the thermostat reaches a certain degree... it switches the fan on.. very simple to do...

thanks a lot man,

here you go....http://www.performancetransparts.com...ROD&ProdID=393 you can get a 16in fan .. that should do the trick...

ok im gonna get it, and the instructions should be there right, it would be ,put fan in place and connect it to these and itll work right
oh i was planning to go to the junkyard and pick up a AC auxiliary fan from another e30 and put it in front of the engine, do u think i should get for now while i save up for the 16in fan or do i have to get the 16in fan now

The work to replace the aux fan is not hard but need more things removed to get to it. Is the aux fan bad? You never stated it was bad. My original died and then got a used one, and it froze after 2 months. So pulling a used one could lead to the same thing. And to do the work all over again would suck. So mayabe your fan is good and its something electrical. I have just gone thru everything to learn the aux fan system. I bought a new Spal 14 and replaced the aux fan. Used stock wiring and even the resister for 2 speed. I have pics on m42club forum under my profile. This fan is suppose to be enough to even cool my engine, so next stop is to remove fan clutch for a week to test it out. If the aux temp switch is working then as temp goes on, aux fan will turn on, if I am not using the AC. I am also in florida so that's why I am being careful. Already rebuilt it due to start of engine overheating.

my ac fan is working i just want another one for lower speed in front of the radiator becuz the ac fan has to go throught the condenser and the radiator before it touches the engine so that is almos no air going in

now I understand, you want to use a bmw aux fan as you electric fan. Good luck getting one and also they are heavy, will add more weight. But unless you add a resistor, the fan will only work in high which might be to much air or it will be very loud, especially if the fan is noisy to start with(since it used).

dont do that... go to ebay and buy and electric fan for like 20 bucks.... it works great...

you can also find a e36 318ti radiator fan which is nicer but not sure how much. I went with Spal, better quality and warranty but it is not needed. Autozone sells cheap ones also.

go for it.. make sure to get something that is 12 - 16 inches better cool down..

ok im gonna see if ebay has som spal fans, also i went to the junkyard today and man all the bmws had the auxfan taken off,
do you think this will work

Those would work, I got my Spal 14" High Performance with curved blades on ebay. Much cheaper than anything local or on internet.
