240sx Radiator and Fan Test

[rico05]

I've had my Alty fans in for a few weeks now. Pretty easy to wire in. And YES, you have to trim the shroud to get it to fit. My tems are about 5-8 degrees cooler according to my water temp gauge un the upper rad hose.

someone tell me where to get a under panel?

IF you still have the black plastic under the engine bay that yo have to remove to either get to a CAI filter or anything in the front underside of the car then I believe you already have the underbody panel. Underbody panel = splash shield I think they just made one for their purposes, but could have bought it.

well the reason I ask is because when my fan clucth went out my fan was constantly on. When I would rev it the engine would sound like it does when it first starts up. U know the loud whrirring sound. Anyway the fan puts tremedous load on the engine. So after I noticed I was only getting 180 miles per tank , I noticed the fan noise. Upon inspection with the engine off the fan was immovable , no free spin at all. That is a broken fan clutch. Free spin is good , as long as your KA is not overheating. That weird noise might be your timing chain tensioners (rolling rocks in a bucket). So I went to the junk yard , found one with very smooth free spin ( when the engine gets hot the fan clucth "locks up" hence the clutch part , so if it locks up when it is cold , its broken) for $25 bucks. Pls bear in mind that thing is a beehive to get on and off so don't mis- DG. Good luck.

are you sure? i thought it must be a one way clutch since it is connected to the water pump? it freewills back and forth so... damn i dunno what to think now...

I have looked at the fan clutch before, I thought it was an electronicly controlled clutch originally but it is just a copper coil that expands and when it unwinds enough it freezes the clutch. Just like an oldstyle thermostat.

And that site is bookmarked!

Sure as rain dude. If your car is not overheating it is not the fan. On the other hand if your fan is making alot of noise and your getting crappy gas mileage , it is the fan. Also if your fan doesn't spin (either which way) when the engine is off , it is broken. trust me .
