Which fan controller?

I just received my electric fans and I am kinda confused on which fan controller to use. I have two fans and don't want a controller that will use up too many amps cause i have some problems with my alternator and underdrive pullies that i'm in the process of sorting out.

It's not the co.stroller that's gonna draw amps. It's the fans. You need to have a controller with a big enough relay so the fans don't kill it.

P.s. if you are already having charging issues then I wouldn't even try to hook up the fan yet. They draw a lot of power.

Re: Which fan controller?

Shoot, well the battery is being charged fine but at idle it'll lose amps at a pretty decent pace. Tomorrow I am going to try to put the stock alternator pulley back on. I noticed that my stock alternator will rotate pretty easily but this new one doesnt. I was wondering if that could be affecting anything. I dont really have any experiance at all with this stuff.

+1000.


Toss those UD pulleys and reinstall the factory pulleys.
Also purchase and install a 130 Amp 3G alternator.
Electric fans will draw 20-30 amps running and can spike up to 70 amps when starting, so you need to size the relays accordingly. A good 60-70 amp relay should handle your fans ok.

Re: Which fan controller?

Thanks, Do you have any good links to find that part. I already installed the 130 amp alternator and the UD's are still making it read low amps

Do you think If i just replace the alternator pulley with the stock pulley off of the original alternator it would be fine? Also, what do i do with the rectifier plug that doesn't go into the 3g? I just electrical taped it and left it.

just go to summit racing.com and search fan controller. they have nice kits including adjustable ones. big selection

also you may still have charging issues if you leave the ud crank pulley and just change back the alternator pulley. but hard to say.

Summit has the 70 Amp relays, but they are expensive.
You can probably get them cheaper at your local auto parts store and not have to pay so much for the Painless name.

Here is a video telling how to wire the 3G alternator properly.

You can usually get by with as small as a 60 Amp.
I just tend to over do things because once I have done them I don't like doing them over.

Re: Which fan controller?

Cool, thanks a bunch guys. I kinda wanna get a more basic one that will turn on at a certain temp and turn off at a set temp. What temperatures would be ideal? or would this vary?

Yeah, that's why I went adjustable. It's gonna vary just by where you install your sensor. With an adjustable you can have it turn on and off where ever you want.

But if your set on a fixed one, I'm not to sure.

It needs to be adjustable and set to work in conjunction with the thermostat temp.
On around 195-200 & Off around 180-185.


You will still need the relay with the thermostatic control.
The relay is used to transfer the power to the fan motor and the control will trigger the relay as to when to do that.

Re: Which fan controller?

Thanks a bunch guys, hopefully this install goes well. is it a big deal if I just don't use the rectifier plug for the alternator?

If it shows it hooked up in the info I posted for you then you should hook it up or you may shorten the life of your alternator or it may not work properly.

Re: Which fan controller?

Alrite thanks a bunch, I have one last question, i have my smog pump bypassed but i have never removed it. What are the pros and cons of removing it and is it just a matter of taking off the hoses and unbolting it?

Pretty much. There are tubes on the back of the heads and to the exhaust that will need to be removed and capped/plugged off too.

Nice, how'd you recommend blocking those off? I wanna do it once well, so i don't have to worry about it later on down the road.

A short (1/2-3/4") length 5/8 11 bolt with thread sealant will plug the holes in the back of the heads.

Re: Which fan controller?

Nice, the fans i got say they draw 11 amps. I have two separate fans. Would this fan controller with built in 60 amp relay work?

It will work, I just don't like the ones that the probe just sticks into the radiator fins instead of being immersed in the coolant. Their accuracy leaves a lot to be desired.
If you use it, try to get the probe into the fins as close to the upper radiator hose outlet as possible. That is where the hot water returns to the radiator from the engine, so maybe it will help increase the accuracy a bit.

Re: Which fan controller?

They have the same controller with a thread in sensor instead of the rad probe. Is that what your recommending? btw thanks a bunch for all the help.

Yes. Thread in sensor is way better.

Re: Which fan controller?

Cool, and one controller will be alright with the 60 amp relay and a/c override circuit for two fans that draw 11 amps together.
