SPAL fan wiring...2gnt HELP!!

Dude that title post makes it seem like you are in dire need or very frusterated. It is very, very simple. If you installed a turbo kit, this should be a breeze.

If you mean, 'isn't possible tto do through the factory harness', I'm assuming you mean they clip together. They should, and if they don't or didn't, cut the harnesses off and solder up the wires. It's 2 basic wires of what you previously stated. Black=negative. Blue/Red usually means positive.

Have you tried hooking it up yet?

 

He said the passenger side, that harness has 4 wires. I thought that was the AC fan harness. Blitzs correct if you are referring to the driver's side harness... that only has 2/3 wires.

 

Why would you need your fan on all the time? If you have a poper cooling system it doesn't matter what you throw at your engine. Even if you were close to 800HP you'd just need a methanol injection kit. You don't need your fan on all the time.

 

*proper cooling system*

 

Also if you are having cooling issues, you might want to check the whole system and maybe check your head gasket or your head for warpage. The only thing that would raise your temps that high is a weak link in you Cooling sys. or head problems. Even a stock cooling system will handle a turbo setup so long as your water pump is in good condition.

 

Are you taking a look at the OP's question? He bought a new radiator and it came with the fan. He wants to know how to hook up the fan, not how to run a proper cooling system...

 

Yeah, I sure did. He wants it to run all the time. That's an easy way to fry a fan in no time. I'm trying to save him that headache. I know if I just spent a bunch of money on a visteon w/fan, I wouldn't want to spend money on another in the near future. Especially if it was due to bad advice from the internet. If you can cover your back from the get go, wouldn't you want to? Wouldn't it be better to let you know whats gonna happen before you shoot yourself in the foot? Not to mention that his grammer and spelling were questionable.

 

I don't know we went from a fan wire up to cooling system. You need to realize that the fan won't be on the entire time if he hooks it up the way I stated earlier. You also need to realize the fan kicks on after a certain run/heat time, so don't assume they're on all the time. On top of that, the OP requested for how to hook it up so it will run properly under operating temperatures, he didn't ask how to have it run ALL THE TIME under extreme temerature. Don't twist it up.

As for proper cooling up to 800HP, you obviously aren't boost. 420a's are plauged with alot of underhood heat, any extra cooling you can get is worth it.

The passenger side is the A/C, driver's side is the radiator. If you are hooking up both, use the same method as I stated. I reccommend push style.

Don't be so critical. You've got some misinformation going on yourself there, champ.

 

Actually he does state that he wants to know how to make the fan "come on at the time" I thik he meant to say all the time so that's where he got tha from. His next sentence confimsthat because he says If he can't do that THEN he wants to know how to ake it come on when the car comes up to temp. Anyway I wonder this too because both harness's on the driver and passenger side have 4 wires and the spal van that the visteon comes with is a two wire get up. Blue and black and the blue is marked possitive. Now Easy way I can hook up the blue wire to the ignition source that goes to my boost guage(It's the tinted kind with light) and hook the ground up to a sepreate ground on the car and be done with it but like it was stated that's not good for the fan. So the big question is which side harnss to do you hack and which wires do you use when you do hack.

 

OK, like I said earlier, and I'm not repeating this again, is that you can't hook it up to the factory harness and have it on all the time, therefore you would need to wire it for operating temperature. Refernce to paragraph two of the original post. Rather then LD criticizing him about why NOT to hook it up to be on all the time(something that can't even be done- so why talk down about it?), I was pointing out that it isn't possible to hook it up all the time with the factory harness, therefore it would activate when the operating temperature is reached. No need to criticize someone over something that isn't possible with the factory harness; but to help constructively and adress the next issue stated in paragraph three. So yes, you are correct, he did ask for all the time with the factory harness, but as I stated it wouldn't be possible and you'd need to wire it differently. You just reiterated what we already clarified and moved on from.

Slippi: So the big question is which side harnss to do you hack and which wires do you use when you do hack The driver's side. I just literally cut off the harness (had a universal push style fan) and re-soldered the black and blue wires together. The harness doesn't control when the fan is on, the ECU does. So you don't even need a direct clip on.

Any other questions we haven't covered?

Oh and Paul thanks for that configuration, it's clear cut, and I'm sure it's more helpful than any of our posts. .

 

I wasn't really concerned about the debate about how to hook it up al the time to be honest I just wanted to know which side pigtail to cut and T into. The problem is there are 4 wires and you just say black and blue. There is a blue/white, black/white and two black wires on the driver side harness. Which wires did you hook up to the blue ad black wire?

 

Let's see, if there are black/white, then blue/white, which two do you think I'm referring to??? They both have white, so why would that need to be clarified if the difference between the two are blue vs. black wires?

Either way, I don't recall white wires on the driver's side. Yes, I did say there is just black and blue and I don't know what 4 wires you are referring to with that problem.

Here are pics. Notice both sides, one side is from the factory wires (blue and black) and one goes to my fan(blue and black also). No white wires involved. Just cut, solder, shrink wrap, and tuck.





Yeah I know the soldering isn't so great but it was done in a frantic rush as my car was overheating in an empty lot. Haha. Hope this clarifys the driver's side atleast..

 

Not to sound like smart ass, but...

 

Very interesting... cause mine looks like blitz's. I know for that the stock fan is a multi speed fan so there should only be one ground and the rest you can solder together as a single positive... But I'm not sure which one that ground is.

 

Same as mine.... Follow VelocitàPaola's post thats exactly what i did with my 2 knock off ebay slim fans and it works just fine

 

Two things which fan was on the driver side the condenser fan? EVen with that said I'm not the best at reading wiring diagrams how do you distinguish between the two black wires?

 

Not sure i understand what your asking...?

You don't have to, you just solder the two neg's together then to the neg wire on the fan and solder the two positive wires together then to the positive wire on the fan. Do that on both sides and your done.

 

Git ya well let me give it a shot. So in a nut shell connect both negs and hook them up to the black wire and hook both the other wires up and hook it to the blue wire.

 

Sounds like ya got it!

But just to simplify things,

Drivers side,


Connect White wire with blue stripe, and White wire with black stripe, to blue wire on fan, Then connect the two black wires to the black wire on the fan.

Pass. side,

Connect blue wire, and blue wire with white stripe, to blue wire on fan, Then connect black wire, and blue wire with black stripe, to black wire on fan. There ya go

 

Makes sense.... Good luck!
