Electric Fan(s)

Post by **scotty-2-forty** » Tue Aug 17, 2004 3:02 am

Interested to know what brand of electric radiator fan(s) you guys are using on your KAT if you've switched from the clutch fan. Please share your brand, size and specs and any complications or praises.

you shouldnt need a dual setup unless you like overkill

but--i have used my a/c fan ahrdwired for a LONG time and not once had a problem with over heating. And i live in cola , s.c. and the summers here are HOT and HUMID.I have thought about switching to the FAL 12 or 14" though--if youre looking for an aftermarjet brand go with FAL. check their Black beauty fan. its slimlineand black and very stealth.

What kind of cfm should I be considering?

Also, what about brands like Perma-Cool, TCI, or one's like Summit's own?

I've had FAL in the past and yes while excellent, they are also expensive ... and my budget has gone to sh*t lately.

I have the dual flex-a-lite 210 in my car for over two years and haven't had a problem. The only issue was installation as the fan is a tight fit on the stock radiator.

get the summit brand one. Unless your car is prone to over heating, then aANY fan should do the trick. Like I siad--ive been using the stock a/c(condensor fan) for almost 2 years. not one over heating probelm yet.

my boy and I just installed an altima dual fan on his s14. Its a tricky install but works very well.

Post by **nab911** » Tue Aug 17, 2004 3:02 am

I just picked up one sitting at the shop the other day for $20 and threw it on and wired it to a switch and havnt had any problems scince.

Post by **WDRacing** » Tue Aug 17, 2004 3:02 am

http://store.summitracing.com/ part # is FLX-210 I like these cause they fit well and are low profile for plenty of working room and 2500 CFM is alot of cooling power. A tad expensive, but my first choice.

Part # PRM-19126 is a single thats affordable. No adjustable thermostat though, you'll have to wire your own. Those would be my 2 choices. I use Summit for everything possible. They have the best customer service and shipping out of anybody I've ever used. But I'm sure you used them for a ton of stuff being in the performance world.

Let us know what you pick and how it mounts up.

The stock A/C fan works for me, I have enen used stock GM fans found at most all local junkyard for about $20 if not cheaper. Nick

Post by **scotty-2-forty** » Tue Aug 17, 2004 3:02 am

Thanks for all of your insight(s).

Here's something else ... First, why or why wouldn't I need an "adjustable" thermo-sensor?

Second, what about that A/C fan? If I leave it, how's the radiator electric fan to be installed?? Ideas???

Fans are NOT my expertise! I appreciate all of your help.

Post by **WDRacing** » Tue Aug 17, 2004 3:02 am

Well you could hard wire it to a constant on or a toggle switch, but then you have to remember to turn it on. Or the car takes alot longer to heat up.

I'd really prefer for it to operate on it's own. So I know that I want to install a thermo-sensor; I just don't see the benefit of the "adjustable" one. Also, I edited my post during your answer. Any thoughts on the later??

Post by **Smurf6x6** » Tue Aug 17, 2004 3:02 am

About the a/c fan. Couldn't you just hard wire it into a switched power on the car. I'm guessing if I do this it will take a longer time to warm up. If i wire it into a constant and put a switch on it, I just turn it on when the cars warm. Right?

Post by **WDRacing** » Tue Aug 17, 2004 3:02 am

I never thought of the AC fan, I haven't done the elec fan mod on mine yet. I'm probably just going to lose my AC fan. The 2500cfm elec puller will more then compensate for it.

Post by **MaxType 240** » Tue Aug 17, 2004 3:02 am

Check out my FLX-210 setup on my cardomain site. I took the time to make a mini-install guide w/ photos (page 7). I've had it running for 1yr now (1 fan full-time, the other w/ A/C).

It's a great fitment w/ the GReddy rad, I only used one zip tie to secure it.

How 'bout ...

Do you think a dual fan unit is necessary due to my keeping the a/c? Or do you think I could wire a single fan to both the radiator temp sensor and the ECU for controlling the a/c?

... in other words if the fan is not in operation due to lower radiator temps and I turn on the a/c, it would then activate the fan. But, if the fan is already running due to higher radiator temps and I turn on the a/c, well it's already running.

Thoughts??

My fan stock fan pops on once in a while in heavy traffic. I get going the intercooler keeps the air going to the engine cool enough. The temp doesn't rise higher than half way up. If I run into cooling issues then I will deal with it. For right now my car is fine.

Post by **Projex240** » Tue Aug 17, 2004 3:02 am

I have heard the altima fans work well....

they can be had for cheap.

Post by **S14tat** » Tue Aug 17, 2004 3:02 am

i have a 90 sentra fan working. one is a 12 inch fan and the other is a 11 inch fan. they work really well and can be had for dirt cheap. its simple to wire up too, just wire both fans in series, and wire it up to the power and ground for the a/c fan.

the stock a/c fan turns on when it sees a certain temp being reach and it will shut off on its own when the temp cools down. the temp that it turns on is not even noticable on the temp sensor. and my car use to overheat all the time, even in a 68 degree day where i'm stuck in traffic the temp would creep up. with the new setup i have sat in traffic for 3 hours with the a/c on at full blast in 90 degree days and the temp needle doesn't even budge.

the only downfall for hte setup is thawt you need to make custom brackets to mount on. the fans are only 70 bucks at a junkyard. they sure beat spending over 200 on a FAL fan.

Same here...

My choice ... recieved it today

... FLX-210B (twin 10" fans with adjustable thermostat and a/c control). I also bought a used FSR aluminum radiator, however for an SR20 setup. It came with a crossover tube since it was being used on a KA setup by the previous owner. I will not be using the new fan brackets and I will also have to cut the bottom of the fan casing for use with my radiator. But hey, I saved about 2-300 bucks over a new aluminum radiator ... even though I'm now on a tighter budget, I still believe in quality

. Once it's installed, you'll never know the fan casing was modified. It'll be a few days before installing, but I'll post pics when it's done. Thanks for everyone's input.

Post by **scotty-2-forty** » Tue Aug 17, 2004 3:02 am

Here are the modifications I made to install the fan assembly on the FSR radiator.

If anyone has tips on polishing the upper radiator tank to a mirror finish I would greatly appreciate it.

First I cut out a semi-circle to fit around the bottom port and cut a notch for the coolant drain ...

Then, I shaved the bottom lip and corners to flush against the core ...

Finally, I cut the outer rubber trim to fit and installed to the radiator resulting in a flush and tight fit ...

Hope this information is useful for anyone trying to fit the largest possible dual fans on a smaller radiator core.

Who'd you go through to get the 210's?

Post by **MaxType 240** » Tue Aug 17, 2004 3:02 am

I hope you didn't spend extra for the temp sensor box. I paid $210 from Summit w/ the box and that thing is a POS. It's bulky, requires a lot of wiring, it's failed twice on my buddy's SR. Use the wiring already existing in the car.

Have the 2nd fan kick on w/ A/C or when the coolant temp sensor hits 90C.

It's about time you got some decent cooling... Go w/ straight distilled water and Redline Water Wetter or Royal Purple's version.

Well, I got the 210B which comes with the thermostatic control and A/C relay. Yeah, it's not a real pretty box, but there are ways of making it less visible. Sorry to hear about your buddy's experience. I'll take your suggestions to heart though, thanks. And yes, I already have a bottle of Water Wetter waiting to be used.

Oh, and WDRacing ... Summit, who else?

Not to thread jack but, Jesse I have been trying to get to you for a while now, could ya e-mail me at [email protected]

On topic= I just have a single electric fan hooked up to a manual switch for my KA-T. Has worked fine for me in 90+ degree weather.

What did you use to cut the fans? I have to do something very similar but I don't know what to use to cut them

Post by **WDRacing** » Wed Sep 01, 2004 5:34 am

A jig saw works wonders, cheap one from home depot for 38 bucks will cut any plastic or wood. High speed die grinder will work to.

Post by **scotty-2-forty** » Wed Sep 01, 2004 5:24 pm

I used a hole saw for the port cut-out and a handsaw for the rest of the cutting (fine tooth). Very simple to do ... BTW, I am selling the radiator shown here in the pics due to my receiving another one from my wife for my birthday; go here, http://www.nissaninfiniticlub....80755 for info (no the fans are not included). Guess I jumped the gun on that purchase ... thanks hun (wife)!!

Post by **Aaron_9349** » Wed Sep 01, 2004 9:03 pm

You guys with your straight water and redline suck, I hate livin in Wisconsin and having antifreeze!

Good info on the fans and fitment though, helps a bunch. Did you run into any problems fitting it to the Greddy Radiator though, cause thats what I'll probably go with.

Thanks
