I am planning to install an electric fan on my s14 soon but I don't want to have the A/C rely on the new fan so I am trying to decide if the stock e-fan will fit on the other side of the A/C condensor and I'd like to know how hard it would be to get it in there before I start taking apart the front end.

I don't know if anyone else has thought of this or attempted it but any ideas would be great.

You want to install puller or pusher electrical fans? If your installing puller fans, you will not need to relocate your stock-e fan. FYI, I did not need to remove the front end in order to remove the stock-efan...

I guess its a bit confusing. I have a pusher e-fan that I want to install but I don't want to remove the stock e-fan from the car. I want to install the stock fan on the other side of the radiator (check out the pic) and reverse the direction so that it is pulling air through the radiator and condensor. That way I can install my other fan on the engine side of the radiator as a pusher.

I also don't know how exactly is the best way to squeeze the fan into that area.

This is where I want to put the stock fan.

Can't see pic, but you don't want to put anything in front of the radiator (on the bumper side).

Don't underestimate the cooling power of the clutch fan.

The stock a/c fan is already in that location....

If you put a pusher fan on the engine side of the radiator... you'll be blowing air out of through the front of the car....

Ugh, let me try to explain again:

I know all about what direction I need the fans to blow. I know that they both need to be bringing air into the engine bay and not blowing out the front of the bumper.

What I want to do is take the stock fan from its stock position and put it on the other side of the radiator and condensor which would be between the bumper and condensor where the arrow points in the picture.
I specifically want to use the stock e-fan because it doesn't have a shroud on it and therefore will not restrict the radiator. The fan that I will be using on the engine side of the radiator has a shroud and so I can't use it in the other location.

I also know that to do that I will have to reverse the direction of the fan so that it pulls air into the engine bay so don't worry about that aspect of the plan.

What I want to know is has anyone done this before, how hard is it, will it fit there, and is there a way to get the fan into that position without removing the radiator and condensor or the entire front bumper assembly?

I don't see the point. Incoming air is gonna be moving a hellofalot faster than that fan pushes. If you're parked and it's overheating, you've got other issues.

The clutch fan more than does its job. It works just peachy. If you want better cooling, get a quality e-fan setup and a water temp gauge to monitor the differences.

It's a different idea, I just think it won't help in the slightest.

It wont cool any better - in fact it will probably make it worse by dragging one of the fans back.

i was also thinking of doing this when im sitting in the staging lanes @ the track waiting to run.

I think he wants to run a EFAN that pushes towards the motor.. IF its to cool while you wait at a motor sports event, do it. Otherwise the OEM clutch fan is plenty good enough.

A quality (mishimoto, koyo, etc.) radiatior will be loads better imo.

Well I don't do events nor am I some street racer or something and I've never had a problem with my car getting too hot, and I live in north GA and run the A/C pretty constantly. I just like working on my car and squeezing a little more power from the engine is always fun. Plus I like trying new things that haven't been done much.

The main reason I want to install an e-fan is for the room in the bay. And I don't want the A/C to rely on the new fan because I figure it has its own fan on top of the clutch fan for a reason and therefore I just thought I'd keep the systems seperate. I will be installing a dedicated temperature switch for the new fan anyway, so I won't be using the wires or relays from the original fan.

But my question has been answered in that nobody has done it before and its probably gonna be a bitch to get it in the space. Guess its time to crack my knuckles and jump on it or rethink the design.

The AC fan is separate so it can come on when needed and not run 24/7.

Installing a quality e-fan setup in place of the clutch fan is perfectly fine.

Our issues aren't the space. Our issues is A: You really don't need it, and B: More than likely it will HURT your temps, and you don't have a water temp gauge to tell.

Removing the clutch fan will free up a tiny bit of power, but you don't want to try this. You don't do any tracking, I can't see this working. You're putting a large object in the path of the airflow.

We're just trying to be helpful.

Oh don't think I am not listening to what everyone is saying and I do appreciate the feedback. I haven't jumped on it yet and I am not on a deadline, I just wanted to know what people thought. I'm not acting like some we know around here (*Cough cough* rbdrifter...)

I guess I might just do the usual e-fan setup when I get around to it.

Good call :) Would really recommend the water temp gauge at that point. Only way to know if the E-fans help or if you should put the clutch fan back on.

Just out of curiosity, does anyone know which stock temperature switch everyone uses? I've read in several places that you can use ones from old GM and Cadillac coolant systems but nobody specifies which ones.

I don't want to use the ones that Advance and AutoZone have for aftermarket fans because they all use the probe that goes between the fins of the radiator and I want to use one that actually taps the coolant hoses.

I have just about decided to drop the e-fan I had in mind and pick up the usual dual altima/maxima fans that everyone uses and wire one to work with the stock A/C wiring and the second to the thermoswitch I am trying to find.

Still haven't found the switch that everyone refers to. If anyone has used OEM thermoswitches please let me know which ones you've used and at what temperatures they turn off and on. I am aiming for ON:185*/OFF:175*.

What temps does the s13 lower radiator hose sensor work?

The s13 lower radiator hose temperature switch is honestly useless. It will turn on or 'close circuit' at around 200F.

Oh no, thats way too hot for normal driving. Not even close to what I was aiming for. I've been looking through NAPAs database since they seem to be the only ones who have the actual specs for individual sensors on their website but I haven't really found much that is in the temperature range. Most things are either up in the 220* range or down in the 160* so I am still looking.
Please if anyone knows of a specific model car that is in the range of 185-190* let me know because I know that plenty of people have done it before this way. I know someone knows.

HEY I had heard a rumor that taking out the clutch fan and replacing it with a 17' e-fan was way better power wise and milage wise ? If any1 could give me more feedback oh this id b great I alos had thought about doing but I wanted way more info on the subject b4 i do something like that!?

Research would have been your friend....

It will free up a sliiiiiiight drain, but most e-fan setups aren't nearly as effective.

Odds are if you're asking this, you're not at the power level where you need to worry about it.

^agreed.

On most cars, the OEM clutch fan and shroud is plenty effective. Im not sure about the efficiency of the KA shroud and fan, but on 2JZ motors (NA and turbo) the stock oem setup flows more CFM and is more efficient than any electric setups, up until the 1200+hp, 8-9sec 1/4mile range.

Unless you are 500+whp and race/drift/time attack/etc. the stock setup + upgraded rad/thermo should be sufficient.
