Sounds good. You hotwired a fuel pump and you don't know how to hotwire a radiator? it's almost the same thing. lol.

Dave from manti seen you with one before. so that's not going to work. lol.

I see one major thing missing. A fuse on the positive wire coming off the battery.
Heavy gauge wire + short to ground = Large fire

I was going to add a fuse to the whole deal, but then I decided a fire would be more fun. I know I talked about a fire in my first post.

That made me LOL!

Happy b-day by the way.

It's not nessaccery if you use a smaller size wire. About the one I'm using. The switch controls when you want it on anyway, I haven't had any problem with mine for the last two, almost three years of running my radiator like this at all. Eitherway, the switch can only draw out 12v at the most, otherwise it burns out. That's why I'm using a wire that is a lot smaller. For got what gauge it was. But if your wire is too big, or more then the switch can carry, the switch will die on you, but it won't blow or lit something on fire. lol. At least it hasn't happen to me yet.

BAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAH.

Well it's you car you can hook it up however you want.

Wow.

Really?

I mean really?

wow.

oh my.

seriously.

no, I'm seriously serious.



First off. Don't argue with the electrial engineer. As much as us mechanical engineers think they are bottle sucking babies, they usually know what they are talking about.

Second. In this particular instance he knows what he's talking about. You see, the fan will draw whatever current it wants to reach it's proper watts. You need the correct sizing of wire to keep the current from overheating the wire to the point where it will ignite, start on fire, and burn your car up.

ie: smaller wire = more current, and more current equals more... let's just call it "friction" and more friction equals more chance of fire.

So. Use a big wire. the larger cross section means more available copper for more available electrons, for less heat in the wire.

Also,use a breaker or fuse, so if you do have a wire, let's say heat up, from using to small of a gauge, or because it cut itself open on the fire wall, and grounded out, instead of the wire starting the plastic coating on fire from the heat and melting everything in your engine bay, you will just pop a breaker or burn out a fuse.


Or, fix the problem that your car actually has, and let the ECU run the fan speed and let the fuses that a TEAM of ENGINEERS figured out handle the electrical fun stuff.

Oh well, that's fine by me, or however you "so call smart people do it" as far as I know, the switch will burn out if it the wire gets too hot. I've noticed and it's done it about 4-5 times depending how long I leave it on. I've done it for my car for the last 2, almost 3 years and been perfectly fine. And that's what I noticed/learn, and know.

Not to challenge you, and Not saying that you're wrong, just what I've done and what I know, and what has happened. Experience or brains, I choose experience over brain.

Also, reread what I said since you're so "smart" I didn't tell him to do it, it's what "I" did. I'm not the one saying it's the only way to do it. I see why most people with these car hate being on forums like this. It's as if, sharing my experience is nothing, when some "so call smart ass" bitches about everything when he couldn't really help out much or make a simple diagram but "talk/typed", if he's so damn "smart?"

Much like Ver Fer above me, I really don't care how you hook up the wires on your car.

But this thread is about someone else hooking up a radiator fan for high speeds.

And in order to supply him with the most information possible, and the OPTION of not accidentally burning his car to the ground, we choose to speak out about the fuse, breaker, or possiblity of electrical fire.

I really don't care what you do to your car.

Ver fer thought I was a bit off my rocker when I decided to put one big turbo on my car. But I did it anyway because it was my car.

But if you think that we are "smart people" with no experience you obviously haven't met us.

If you are lucky, your car will never blow a fuse in it's lifetime.

If you are unlucky, and electrical fire can happen, even with a fuse.

But when you do something to your car, you try to minimize the bad.

I'd add the fuse. It's not even expensive.

can oil cooler, mounted in front of the radiator, cause higher water temps?

Yes.

The heat from the oil transfers to the air, which would otherwise only have to pass through the A/C condensor, and the radiator. (and the power steering if you count that... I guess.)

So the air temp will theoretically be higher before it even reaches the radiator.

But it probably won't matter, and will work just fine.

so all I did was, grounded "green with black" wire and my fans working on Hi speed now. no need for a switch or fuse or any other extra wires. but I'm still running kind of hot. new antifreeze (mix). water was evaporating too fast.

water shouldn't really evaporate. It's a sealed system. (up to about what, 10 psi is it? then it forces the stopper up) Have you changed your coolant cap lately? perhaps the rubber seal is kind of sh*tty and is allowing some to escape in the form of steam?
