What year altima for e-fan swap?

[MELLO*SOS]

Hello

What year altimas are you guys getting e-fans from to swap onto your s13 KA24DE w/ stock radiator?

Please no comments about how much better clutch fans are. I need to replace my clutch fan, shroud and electric fan, and the cost of doing all that will outweigh replacing all of it with a set of altima efans.

[aznpoopy]

just do a quick search.

iirc its just the altimas with the ka24 in 'em. i believe stanza fans from the mid 90s work as well.

[MELLO*SOS]

You know I have searched quite a few times, the best I can seem to find are people saying "JUST SEARCH" or "maxima/stanza fans". One person said, "mid 90s", but damn that covers quite a few years.

Let me specify, will 96 or 97 altima fans fit?

At least you didn't link me to the rx7 cooling page again

[WilloW]

To my knowledge 93-94 Altima dual electric fans will work with about 3/4" trimmed off each side of the shroud.

[aznpoopy]

^^ there's your answer for altimas.

lmao.

as for stanza, someone used a 96 stanza fan which is pretty much the same thing. better?

[MELLO*SOS]

Awesome thanks for the response guys. Can't wait to get my drift burro back on the road

Altima/Stanza, and Maxima fans work.. pretty much anything from the newer FWD VG30's. Through my friend's experience using these fans, rather than worry about stock fitment with bolts and such, just buy some strong zipties and make it tight. It wont be going anywhere. Oh yeah, and, use the clutch fan because it is better.

not this again...

the ONLY reason i would say the clutch fan is better is b/c the mechanism is just so much simpler. the clutch fan is BAD b/c it takes up so much damn room in the engine (and it just goes bad on our old ass cars).

e-fans work perfectly fine for drawing in air. otherwise people wouldn't run them on heat sensitive cars (rotary) and manufacturers wouldn't put them in their cars.

e-fan and clutch fan are only useful when the car is moving slowly or idling. neither can match the airflow you get while the car is moving.

Good summary poopy I was going to elaborate but not necessary. Damn I love when you post..............shakey shakey shakey mmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmboobs

[MELLO*SOS]

Yeah

So 1993 altima fans fit after some dremel grinding. They are wedged between the frame rails now, the top held on with a bolt on the driver's side and a ziptie on the passenger side. If there is anything more than a .25" gap between the fans and the rad then cooling is nonexistant. I wired my fans in to the ACC relay, so they're on when the key is on... Definitely no problems with overcooling.

Thanks for the input everyone.

I understand why people like the clutch fan more, but this setup is working fine for me and is 100% more quiet. I am thinking of buying some weatherstriping to use to seal the fan cage to the radiator, as I have a feeling I am loosing a good amount of cooling due to the poor sealing of the efan "shroud".

[aznpoopy]

thanks for the input. now when ppl ask what year altima e-fan we can all just yell at them and tell them to search for the mello88 thread! wewt.

[Andrew Bohan]

so i went lookin for altimas and the junkyard. didn't find any, but me an westborough pimp ended up bringin 6 fans out of there.

i got the AC fans from an AW11:


not done installing em yet. ima have a switch on the dash. i was gonna wire em so they're on when the ignition is on, but with high compression my starter struggles enough as it is...
i just hope i never forget to turn em on
haahaha

[mikespeed95]

i have a bunch of electric honda fans. i was considering diong this. does anyone that drifts have any setup like this? my car runs fine giong straight but without the fan shroud on the clutch fan it overheats like a mofo. i was wanting to switch to junkyard electric fans but didnt know if it woudl work.

i think it was johnny5 in the old e-fan thread that had problems with e-fan set-up at drift events.

uiuc also had alot of good info... i think he basically said it wasn't a problem if you set the fans to come on before they get to hot.

shrouding is very important... if its un-shrouded, neither e-fan or mech-fan will work properly.

[MELLO*SOS]

I'll post a picture of my fans soon too.

The AW11 fans shown installed above look good, because it has a nice shroud. They look 1-2" thicker than the altima fans though.

If I had to swap to efans again, I would not use the altima fans. I think that there has to be something better out there (shroud, slightly smaller width, included temp sensor?, etc). I just figured that since the altima and 240 share the KA24DE that the fans and radiators should be pretty identical..

If anyone is wondering how to wire up their fans, I spliced into the ACC relay, taking power from the blue wire. It is on whenever the key is on, and seems to support the load of the fans quite nicely. I don't know what it's fused at, but since it's accessory I'm guessing 15,20 or 25A... More than enough... I don't even use the cig lighter outlet in my car, so yeah.. I wanted something as automatic as the mechanical fan with no switch to forget to flip on until it's too late.

i used stanza fans from a ka24e stanza, circa who knows year, they have been in the car for like a year or 2, temp never creeps, and yeah, saves a lot of space in the engine bay, i can throw up some pics..they fit perfect with a lil trimming.

[superman0234]

240driver: Throw up the pics, I'd like to see how these compare to altima fans

[sr240mike]

I have 91 stanza fans I planning on installing too. Im just waiting for the adjustable temperature switch to get here from summit. The stanza fan shroud is slightly larger than the ka/sr radiator so it needs to be cut on the sides. The shroud on driftaholic's AW11 fans looks far superior than the stanza's though. Here's the stanza fans

[MELLO*SOS]

sr240Mike those fans are IDENTICAL to what I have on my 240 right now. Since the above posts I made, I have had no cooling problems at all, and the car doesn't sound like a UPS truck during accel.

I have since replaced my radiator, so after I reinstalled my fans I just used zip ties on all four corners. Above I mentioned that the fans have to be very close for good cooling, but I think that might have been due to the fact that I was a little low on coolant at the time. Since these fans don't have the best shroud I think it's still important to get them as close as you can to the radiator for max cooling.

Also, watch out for the AC line (iirc) on the passenger side, as it will sometimes interfere with the passenger side fan. If it's touching the blades (you'll hear it) then your fans aren't close enough to the radiator (or they have slid back!).

When you do the wiring, each fan will have 4 wires. I think they are similar to dual-voice-coil subwoofers, having 2 power pairs (+ and -) for each motor. At first I thought they might somehow control fan speed, but after I played with them a bit I found that was not the case. Just wire up one pair for each motor and you'll be fine.

Here is the lamest wiring schematic you've ever seen:

M = Fan Motor (left/right)

chassis ground <-----[LM]+++++\___ blue ACC relay lead (on with key)
chassis ground <-----[RM]+++++/

Good luck to anyone doing this project, my advice is to do your homework and find something that fits, because you aren't going to enjoy this install.

I have Altima fans (minus the shoe!!) but my fans have pins at the lower part and screws at the top. Minus a small trimming done at the sides (the small strip at the sides) they just dropped like stock, even using both lower pins and top screws!!
I swapped the blades from the AC fan and now both are 5 blades.
Do you guys knew that Altima fans (at least mine) have 2 speeds?
I wired one circuit to an adjustable temp sensor and the other circuit to the AC fan relay, just like stock.
The work superb, even overcools when they are on. The benefit of usingboth circuits independently is that when the sensor activates and the AC is on, they will run on high. If only one condition is met, they will run on low.
They will lower the coolant temp from 192F (after a good highway heatsoak) to 160 in just 2 minutes!! using a MDM-100 as temp gauge
Dunno if this is hurting my engine or not but I have to be carefull at night when running AC or I will frezze inside!! (I live in the tropics, so no winter here!!)

Okay I would like more info on this, because when I got my fans I was surprised that each motor had 4 leads. I thought it might be 1 ground and three hots for 3 speeds each, but after testing I found it to be 2 circuits for each fan (two hots and two grounds). I ran power to each of the circuits and got the same fan speed, so I have them installed and using 1 circuit on each side running 100% of the time.

Do you have to run power to both circuits to get the high speed or what? Until I have some sort of temp switch I think my setup is fine as-is, but I like the thought of wiring the other circuit to the AC fan relay, that makes a lot of sense... I just didn't know that the fans were dual speed!

[240Driver39]

oops forgot bout this thread, but, sr240mike posted up pics of my fans so there ya go for someone askin me to post up pics. they are still chuggin along after like 2 years of using em. And mello is correct, the stanza fans i have are exactly like the altima fans, i looked at a set of altima fans 5 minutes b4 i grabbed mine from the jyard, same thing.

[pr240sx]

Yep, you got that right, each set of wires is one circuit, now beware to wire them correctly so you dont short them!!
Check each wire polarity, the only easy way is to supply power to each set of wires. I even went to the junkyard and use a factory connector. Is the easiest way!!
At least my setup looks, sounds and work like factory.
the leads are one positive and one negative for each motor. Each set of wires activate a different set of windings inside the motor. For high speed the 4 wires must have power. this is when the factory harness helps. Instead of wiring 8 wires, the connector doeas that for you and now you have 4 wires!!
