Electric fans, Yay!! and small update.

[YR240]

I just finished installing my electric fans from a 2008 altima. I am very thankful for everyone that has done a writeup on this subject because without them... who knows. It is wired off the ACCY that actuates a relay, then to a temperature sensor that kicks the fans on at warm. Here are some pics.

This is the coolant that I used, I am not sure how it will work out, anyone tried this stuff?This is the grill I did. I have posted it before, so re post I guess New rims, great deal on Craigslist. waiting for itchibans to correct offsets.I broke the little pins a while back on the shifter trim and finally did something about it thanks for looking

[YR240]

Just went for a drive and noticed that it pulls harder at lower RPM. I have a VLSD that I will be putting in next week. I guess that I am getting ready for the engine swap, just doing all the other stuff first.

Cool, no pun intended. Could you give a little more info on how you wired it up, maybe a diagram ?

[AZ89two4Tsx]

You can actually feel a difference? I know I'll be doing this when I go KA-T. I hate that loud clutch fan. Plus you've got alot more room, it's a win-win!

[YR240]

Here is a wiring diagram of what I did. Shame on me for using the Radio signal as my relay trigger, but my radio doesn't work as it is. I used the stock A/C fan harness to power one fan, the one that seems to move a little slower, and the diagram shows the rest.

Here is the Temp switch. http://www.oreillyauto.com/EW3...age=1

I noticed the difference when Accelerating at low RPM, something I had grown accustomed to is when on heavy acceleration, there would be a lag up to about 3000 rpms. I know this is only a shadow of what the engine swap will be like.

I can't wait to get the differential installed. Right now when I spin the tires around a turn the weight shifts toward the outside and the inside tire comes off the ground just enough to have all the open diff power transferred to it. The wheel with the weight of the rear end stops moving and the car grabs then straightens out.

[YR240]

Does any one know if they make a timer delay that will not send the fans signal for may 5-10 seconds while the car is being cranked. I think that the fans are a bit draining on the battery when the car is warm.

[MastaYu]

^ you can get a fan controller, which lets the fans kick in at a certain temp.

[Warped161]

yeah they even sell them at autozone its a simple fan controller that you can set the on temp for.

[YR240]

I have that already, that is why I said when the car is already warm. I am looking for a timed delay relay. that means that the relay gets power and from that point waits x seconds to kick on. I already have the one that kicks on at a certain temp, its posted further up in the thread.

[s13beast]

I think i passed your car in daphne a few weeks ago...

[locoluna825]

got my electric fan wired up to my cigarette lighter who uses it anyway i also run the temperature sensor so when its war it kicks on immediately when they key is in ON position. Dont really care about that id rather live with it than bother, i had quiet and experience with electric fans ( car caught on fire:oy: ), yea what your looking for is a timed delayed relay it would be the same kind your running now but when it energizes it takes about 5 seconds for the contacts to touch. instead of the normal kind which immediately touch.

you can probably poke around the internet and find something like that for electric fans

You're missing a header stud/nut.

[Nissan Junky]

No that we are on the subject>my s13 ka24e that i bought has a single fan that runs good but i think its not wired right,it is wired up to the fuel pump relay and so when the pump is on the fan is on also.So do you guys think that is right or am i just tripping

[Nissan Junky]

bump?

[numbnuts240]

solder and heat shrink those wires, that looks horrible as it is.

That is exactly how my car caught on fire, yoru running a relay and fuse on that fan set up to right? if so you should be fine but you really should have that running on the accessory, its stealing amperage from yoru fuel pump like that sooo... yea. i ran mine to the cigarette lighter like i said before 14v source ;D

[mrgreeneyes]

not to be a d!ck, but i hope you all realize "wiring work" isnt just finding a way to make 2 wires touch, its creating a quality connection, insulating that connection, doing the math to make sure you have the right wires/fuses/relays/terminals, and routing/wrapping it all cleanly.

this is an example of "i made it function on a basic level", not of textbook wiring work

Its not on its own relay its just wired up to the fuse where the fuel pump goes.So you think i need to relocate the wire and if so will you help me out on how to do it.Do i just find the cigarette lighter wire and just tap into it or is there more to it if that's the case is a no bran-er if i am wrong just let me know.

[locoluna825]

its a no "bran-er" run a wire to the cigarette lighter you never use the lighter anyways it'll be the best ""i made it function on a basic level"" thing you ever did and go get a relay and fuse for that

[mrgreeneyes]

its a no "bran-er"

b-r-a-i-n. brain. the thing that all of us (except for you, obviously) use to think good wholesome thoughts with.

not bran. oat bran is contained in some cereals and holds health benefits. why would you want something to be a "no bran-er"? i would love to reap some health benefits.

if its on ACC and not IGN, it should NOT stay on during cranking. cars temporarily turn the ACC off during the START condition, and let it come back on once the key has sprung back to IGN.

for instance:

Key in OFF: Nothing gets power

Key in ACC: Just ACC gets power

Key in IGN: ACC and IGN get power

Key held to START: Just START and IGN are energized until the key is released back to IGN position, then IGN and ACC are left powered on, until the driver turns the car off

That being said, make sure you are on a true ACC, and not an IGN, and your fans will NOT draw current during crank.

Im being nice and helpful as much as i can here. I will answer questions with wiring cus i do NOT want to see some wiring noob burn their car down, just out of sheer ignorance.

What size relay or is that base on the wire size?

[1KleenS13]

What size relay or is that base on the wire size?

I would use a 10ga wire and a 25-30 amp relay for the fans.

[Nissan Junky]

So let me get this right can i run it off my Acc that i do not use because i am not using a fan controller i just want to wire it direct but not to my fuel pump relay?and if i wire it direct do i need to use a relay or a fuse because the car comes with one anyway Right.I dont want to sound like a pain in the a-- but i just dont what to cach on fire if you now what i mean.

[zerepdivad]

Don't wire your fans to your cigarette lighter.... that's just stupid. Have you looked at the wiring size that's on that? If anything go off of your ignition harness, and use a relay.. The fuse for the cig lighters is like a 10 amp fuse, and lets say some jackass drops a penny in your cig lighter..... woops there goes your fans. And you should use the same size wire that your fans have on them. What good would using 10 awg wire do if you're wires off the fans themselves are 16 awg? nothing.

[1KleenS13]

I agree you dont want to run anything off your cigarette lighter, or fuel pump, or any other sensor under the hood. I would use 10ga for the fan motor only. You can trigger the relay with smaller gauge wire. FWIW I dont have a Clutch fan on my car anymore, only the electric fan for the AC and my car doesnt overheat at all, EVEN when its 95 degrees with the AC blasting. My stock electric fan turns on even without the AC on. I also havent really "raced" my car,but its not babied by ANY means.

[bryantkalagian]

i have a rb25 but i only have one fan, and want another one. can i just splice the wires of a new one onto the stock one? are all fans pretty universal?

[locoluna825]

im sorry about the cigarette lighter comment zerepdivad theelite wiring god has pointed something out i didn't even realize. i don't suggest wiring it to your cigarette lighter anymore. ALTHOUGH i have had no problems whatsoever with it setup like that for the past year and i will seek an alternative 12v ign switched source
