i heard that you can take off the clutch fan and still be ok cause you already have the e-fan. is that true. and that by doin so you reduce stress on the motor. so......

 

I wanna know this too..

Honestly, I don't think the efan is big enough to handle all the heat load.

 

yea i feel the same. i dont know if its just me but it seems like ka's produces hella heat.

 

remove the clutch fan and upgrade the mechanical fan. a few hps on the butt dyno. the stock electrical fan kicks in when the water temps gets too hot. it moves enough cfm but id upgrade to be safe

 

The OEM E-Fan that is in your car, it is for the a/c condenser. It only kicks on when the a/c is running to cool the system. You can use this fan it is adequate but still on borderline if you ask me. You need to install a thermatic switch to the fan so that it kicks on, just like you would a normal electric. So why not just buy a real aftermarket fan.

 

i removed my mechanical fan and wired of the efan to run all the time. been thru one summer, this comming summer will be my second. works fine, no overheating issues.

cuz i'm poor

 

Sounds like you've been very, very lucky. The pusher fan isn't nearly big enough to move sufficient air to keep the car from overheating under 30 mph. Even an aftermarket pusher that covers the full height of the radiator is marginal.

 

What if you have a Koyo aluminum radiator and dual 12" Flex-a-Lite fans with a NISMO 149 degree thermostat? Would that sufficiently cool a KA-T?

 

yes.

 

 

^ huh?

 

i have a an oem electric fan on my s13. well i have a s14 radiator, and it cools hella great because i dont have a ac condensor blocking it. to its air cooled and fan cooled.

 

i removed the fan no overheating problems nothing the electric fan only turns on when im idling for a long time at a light or somthing. i noticed a little faster reving nothing spectacular

 

oh god
so you guys wantting to use you ac fan to cool your whole system
good luck on that
clutch fan >any efan
there are some good e fans out there
don't be a cheap ***

 

Also remeber, Aluminum radiator poses no advantage over Coper, sicne coper transmit more heat, So if you have an aluminum radiator, don't remove ur clutch fan. The aluminum one's work better because they make them bigger. And if its thinker than 1 inch, then u better upgrade the fans, not downgrade them.
