Electric Fans

Post by **spec-v5150** » Tue Jul 01, 2003 9:52 am

I have a few questions on electric fans.

First off...how much will running it ALL the time (while driving) affect your battery??? LWhen I had my Isuzu Rodeo when my Bass hit, my battery gauge would go fluctuate. My **** never died out, but......

My 01 Altima has electric fans and they dont run all the time. IS this where the adjustable thermostat comes into play??? How do you wire the thermostat to read the temp and kick on the fans. I was going to do it simple and just run it whenever I dirve. BUt I also dont want to buy new batteries all the time. Ihear these things suck up juice

THE THERMOSTAT IS USUALLY EITHER AN SEPERATE INLINE ONE, OR IT TAPS INTO THE OUTPUT LEAD OF THE CURRENT THERMOSTAT. IF YOU HAVE A STRONG ENOUGH ALTERNATOR YOU WILL NOT HAVE A PROBLEM. OHH AND WITH THE THERMOSTAT METHOD GET ONE THAT'LL COOL BELOW 180F. IF YOU DON'T THE WATER HEATS UP CLOSER TO THE ENGINE AND IT LOSES ITS EFFECT. ALSO GET A FAN IN THE 2000CFM+ RANGE.

Okay.....I think I will just run it all the time.....LOL easier for me.

IF IT RUNS ALL THE TIME GET A SPEED CONTROLLER WITH A MEMORY SETTING. THIS IS SO FOR DAILY DRIVING IT IS A SLOWER SPEED SETTING THEN WHEN YOU DECIDE TO HAUL ***, SWITCH IT TO TOP SPEED FOR MAXIMUM COOLING EFFECT.

ALSO IF YOU PLAN ON RACING LOOK INTO A CRYO PLENUM THAT SITS IN YOUR LOWER RADIATOR HOSE AND COOLS THE OUT GOING WATER BY ABOUT 20-50F.

Hmmmm what would that cost??

THEY HAVE THE INTAKE ONES FOR ABOUT $450 FOR THE WHOLE KIT BUT THATS A SILICONE BOOT, YOU COULD TAKE THE PLENUM OUT AND WELD IT INTO A METAL PIPE FOR COMPLETE STRENGTH OR JUST MATE TO HOSES WITH THE SILICONE BOOT AND THEN USE WATER SEALER.

another question. I was browsing EBAy and came across some decent fans. NOw....do I want one the pulls or one that pushes or get both??? I was thinking both just to be safe but wanted some thoughts before I seriously buy. I want to do as much of this BEFORE I get ym car rolling.

YOU HAVE AN S13 CORRECT? THEN PUSHERS, BECAUSE THE FANS GO ON THE BUMPER SIDE OF THE RADIATOR.

Post by **spec-v5150** » Tue Jul 01, 2003 9:52 am

bumper side....... ? I thought it go would between the radiator and the engine

IT WONT FIT UNLESS YOU GET ULTRA THIN FANS. AND YES YOU CAN DO IT BOTH WAYS. I WAS CONSIDERING QUADRA FANS BUT THE UNDERDRIVE PULLEY IS ONLY LIKE 1.5 INCHES FROM MY RADIATOR.

Post by **PROJECTRB240SX** » Tue Jul 01, 2003 9:52 am

IF YOU PUT IT ON THE BUMPER SIDE AND PLACE A INTERCOOLER RIGHT IN FRONT OF THE FANS IT'LL SERVE A DOUBLE PURPOSE.

What size fans are you guys using?

Post by **PROJECTRB240SX** » Tue Jul 01, 2003 9:52 am

I'M GOING TO USE 2 10" FANS BOTH PUSH.

sounds good..........

I found a good set of dual fans...2780 cfm and thermostat....bu it was likr almost 300 bucks..gotta pay to play I gyuess

do you have to buy specific fans for the 240sx or any fan will do?

Post by **spec-v5150** » Tue Jul 01, 2003 9:52 am

My understanding is that they are universal...to a point. You cant go get an electric fan made for say motorhomes and expect it to fit in your 240. Just an example. I was reading a site that said you wanna cover at LEAST 70% of the radiator.

thanks

I heard pepboys sells some decent ones for pretty cheap so I plan to go there and get some slimline fans, then splice them into the stock harness. no switches...no bs, they go on when they should. this may be an even cheaper option for you.

Or look for someone parting out a later model Altima (98-01) dont know about 93-97 or 2002+. My 01 Altima has electric fans. Dont know the CFM though

Post by **PROJECTRB240SX** » Tue Jul 01, 2003 9:52 am

IF YOU GET 2 10" FANS IT SHOULD COVER OVER 70% OF THE RADIATOR. THE REASON I DON'T THINK I HAVE ROOM IS BECAUSE I AM USING STOCK MOUNTS AND X-MEMBER.

Here's a nice set from Summit http://store.summitracing.com/...=ecat

Should work real well, get the set with the adj thermostat.
