you'd think that wouldn't you? I mean, it only makes sense right?
nah, antifreeze is corrosive, (i think mostly to alum.) which is partially why you don't want to have too much of it in your system.

No. The battery will drain within about 30 minutes once the car is shut off.

well i didnt mean peremantly leave it on but like somehow hook it up to a switch of somesort, i was also thinking of hooking it up to the alternator, that would work as well right?

If you are going to use an electric fan, connect it throuh a thermostat so that it only comes on when needed. The electrical system is already overstressed from the factory, and you want to avoid overcooling the car.

im assuming u dont mean the thermostat for coolant right? where is the temp sens relay that turns the fan on? is there something in or connected to the AC compressor that i could hook that fan to?

ermhuh... no... not a good idea, the current that comes out of the alternater is very dirty, the battery smoothes it out so it's useable for the electronics, it's never a good idea to hook up anything directly to the alternator unless its another battery, or a capacitor.

The alternator is connected directly to the battery at the + terminal. Makes no difference if you connect to the battery or the alternator. The battery, however, is a much more convenient spot. I could draw a schematic to prove this, but I don't have that kind of time....

To the original poster, if your car was originally equipped with an e-fan, you can use that signal to activate a relay to run your aftermarket fan. But that is NOT reliable sine the stock e-fan is only used once the engine gets too hot, or when the A/C is on. Best bet is to get an aftermarket fan thermostat. Summit Racing has a bunch.

I beg to differ, connecting to battery and connecting to alternator are to different objects, yes they are connected to the same line, but the voltage at the alternator is no smoothed out, its a on -off -on dc (almost the same idea as a/c) voltage instead of a nice flat line.
And a schematic won't neccessarily prove it, I understand what you are thinking, (its the same wire, weather or not you connect it at one point or the other doesn't matter, this is true). but the battery itself is a device.

I'll stop writing before I make it more confusing

I'm not confused at all...And I doubt you could confuse me unless what you were writing is wrong. I happen to know a little about electronics, so I'll just leave it at that, sigh and say "whatever".

where is the AC relayt at? my ac stopped working and i assume my fan was hooked to the AC line because it would go on when i turned the AC on. how could i double check if my AC system still works and where is it located? is it possible that i take my ac compressor off since i dont use it and rig my fan to it?

First things first. Grab a copy of the service manual from http://www.fc3s.org

As mentioned before, use an aftermarket thermostat to run your fan. Don't jump it to the stock fan or A/C system.

*sigh* whatever...
right back at ya

I kinda figured you knew "little about electronics" j/k j/k
