HI to all.

Straight to business. My clutch fan is prety much dead. I was thinking about replacing it with a good electric one. What do you have to say about it?

Does it cool better? Does it free up any HP? Is stock alternator good enough? How hard is installation, and what is needed for it?

I wona know EVERYTHING, prefferably from the first hand experience. But will take theories, and speculations. :+). Most important thou - does it cool better, and frees up HP?

Thanks

OK - Lets talk!

Yes - it will free up horsepower because it doesn't have to spin that heavy fan / clutch combination any longer. Yes, the electric fan will cool as well, if not better than the original fan/clutch, assuming you buy one the correct size. Motorsport Auto in California sells the Toronado brand which seem to work well. It is all thermostatically controlled, so the fan will come on by itself, or you can override it with a switch. The stock alternator should work fine. The install is pretty straight forward, the kit comes with all the instructions and is fairly easy to install. Good luck!

Re: OK - Lets talk!

There are three other added benefits that I like from using electric fans too:

--you can adjust the timing without cutting your fingers off.
--the engine is much quieter without that turbine sound
--the water pump bearing has less strain on it.

Is there enough of a benefit to warrant taking out a WORKING regular fan and replacing it with one of these? I have one of the metal fans which ran into my radiator once when I slammed on the breaks - dinged up the fins pretty good but luckily didn't puncture. I'm also having overheating problems when idling.

Brian, your car could benefit from new motor mounts as well as an electric lightweight plastic fan. I really like the Spaal fan on my '78. it moves a ton more air than stock, but it moves so much air that it's pretty loud. it shocks people actually. if you don't like that sort of thing, just go for the curved blade model instead of the straight blades. they are quieter. if you overheat much your radiator may just need rodding out by the local radiator shop. does it leak anywhere?

I know, it's on the list :) I think the fan was a little bent and dangerously close to hitting the radiator at the time, now there will (hopefully!) be enough room.

Shocks people when you open the hood, or causes people to point and laugh when you're sitting at a traffic light? :)
I haven't noticed any radiator leaks. It takes a good 10 minutes of idling to overheat, going up hills the temperature guage stays dead-center.

Personal experience

I've had 5 Z's in the last 8 years, all 280ZX's.
The one I have right now is the one that works coldest of them all. I even thought that the gauge was bad. All the previous Z's ran just in the middle of the gauge, this one runs 1/4 of the gauge.
A couple of months ago I got a HAYDEN high-flow 16 fan from the local pep boys I even bought the thermostat kit. After installation, my Z worked in the middle of the gauge and rised above it when in traffic.
I felt no difference in power(maybe due to the aprox 280 hp on tap)
The fan and clutch were perfectly OK.
After a couple of days I reinstalled the original (belt) fan and everything went to normal again.

So, dont put just any 16 fan (though hayden was supposed to be good)

Good Luck
So I reinstalled

Have you ever checked out JEG's catolog? They have a great assortment of electric fans and super lightweight radiator's, a good setup is their Jester Alum. radiator or others a little bigger but they have a dual fan unit that is made for this unit that keeps my car very cool plus weighs less than half of what the stock radiator weighs. They also have some real nice other electric fans that kick out 2500cfm but the kit by motorsport is nice but I don't like the fan that much. I prefer fans that come with shoruds, makes better use of the fan than non-shrouded ones do.
The HP gain is pretty basic and slight, clutch driven fan's only turn the fan at low RPMs so you only see the gain at take off which is still a important area (if you do a lot of stop and go driving and you will see better gas mileage with them along with other benifits posted here.

it shocks 'em because it's sooooo big, and they laught at the sound at traffic lights because they're expecting an f-14 and all they see is this little car!!!
check your radiator cap for cracks around the seal and proper pressure rating. let me know...

fan clutches

What about fan clutches? I've heard that the aftermarket ones are a different design from the Nissan ones and don't work near as well.

any truth to that?
