no fan on a koyo radiator? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Tidoxp · 09-16-2010, 05:56 AM

two people told me it wasnt a big deal to have a radiator fan with a koyo high performance rad, since it cooled just fine for them. any experience with that?

and does anyone have any reviews on cx racing radiators for an s14 ka24?

You should always use a fan on a radiator. Even with a high performance, thick radiator. Any time you stop....your radiator isn't cooling. I have a CXr rad and it works wonderfully.

no. it might be ok for dding but as so as you go spirited driving your fucked.

A friend of mine Lives there in SD,and he has only been running 1 fan on his CXracing radiator for a little over a year with no over heating problems at all. He has a Kouki Ka24de

Get a fan.

Okinawandrifter87 · 09-16-2010, 06:13 AM

Don't be cheap get a fan. Even if its a clutch fan. Some debate that they even work better, it just takes up more space is all.

i experience this first hand. Before i deleted my clutch-fan, I did not have any problem of over-heating , let alone running a lil hotter than normal. Then i put in an E-fan and my temp would very slightly move above normal before going down to its running temp, it even gets worst when A/C is on.

I think it could be the coolant, wasnt bled right maybe after i change the fans and fluids.

Before or after were you running a stock or nismo thermostat or no thermostat at all?

i was just running stock thermostat and everthing else.

I have a CXR radiator with stock clutch fan and shroud, I had electric fans but I didn't want to deal with the wiring, car idles great, cools fine, just recently replaced the temp sensor for the gauge so I know it's accurate! And when I beat on it it's steady warm.

I totally forgot to ask this question lol.

Sam_Well.13 · 09-16-2010, 09:35 AM

the cluster. HUD have a dot on the temp gauge where it should be at warm running temp. and i would slightly go over that.

Okinawandrifter87 · 09-16-2010, 09:37 AM

Yeah but the cluster gauge is usually not that accurate if I'm not mistaken. I assumed you meant aftermarket.

Sam_Well.13 · 09-16-2010, 09:41 AM

No, i have no aftermarket gauge on my car.

but i see what you're saying, the thing is though, I never had a problem with the gauge needle going over its normal running temp when i had the OE A/C fan, and clutch fan along with the shroud. Now that i have a Ford escort/Taurus fan with its own shroud, my temp would slightly go above normal and gets even worst when A/C is on.

Okinawandrifter87 · 09-16-2010, 09:43 AM

True I know what your saying. However it is only in the general vicinity if it is the oem gauge. You probably want to use an aftermarket of some kind if you want an accurate reading.
