240 electric radiator fan

[foolthrottle]

is anyone useing other than the stock fan in their Z I'm thinking of converting to a single or double electric fan set up for desert driving. Any thoughts?

I dont know about all electric set-up's. I do alot of off road and rock crawling. I did the all elec. on my off road truck because of the low speeds with that stuff. But, after almost blowing a motor because of a bad fan motor I went back with the belt drive fan. Then I added a dual elec. fan set up on the outside as a pusher. One elec. fan stays on all the time and if I see her getting warm I turn on the other fan.

I have found that the late 80's and early 90's ford taurus had a nice dual fan set-up on them. One that runs all the time and a backup fan thats made to kick on with the AC on. Real easy wire up and good shroud that should be a nice fit on a Z.

Here are the pusher fans on my off road rig. They are the ford ones and thin enough that you could fit one or even two if you like.

On my 78 280Z and on my 79 810, I have single electric fans mounted on the front of the air conditioning condenser that come on when the compressor is on but I still retain the stock belt driven clutch fan. With that setup, my temp gauge never goes higher than just below the center even on 100+degree SoCal summer days.

I replaced the stock fan with an electric one. Didn't have any problems with overheating till head problems ended up with coolant leaks and then it would run a bit hot. Bought a fancy controller for the fan that would turn it on at half power when the temp hit one level and then full power when it hit a second level. But never got around to installing it before that Z wound up being a parts car :disappoin due to rust. I also had switched it over to a crossflow single row aluminum radiator (I think out of a full size chevy van or something like that). Used the JTR V8 conversion bottom mount for the radiator and then slightly custom top mounts. And the hoses listed: http://240z.jeromio.com/camaroradiator.html

It would have been nice if it had a shroud but I was able to mount the fan so that the blades were really close to the radiator. So that helped some.

I liked the setup, but just decided on the replacement Z to keep things a bit more simple.

I have the same set-up as sblake01 on my '71 Z with AC and have no problems in 110 degree summer driving in Palm Springs. You probably won't be driving in weather too much warmer than that.

Any issues removing the stock fan blade and clutch? The clutch is just for stabilizing the blades and correcting fan wobble - correct?

Other members have used the Taurus fans-280~Master to name one, and sing its praises all the time, you might also look at a dual fan out of a mid 90s Maxima-that is a common Z32 upgrade-nothing like keeping Nissan under the hood!

Nope, just 4 nuts and the fan assembly comes off, unless you have a shroud, then it's a little tougher. Just put the nuts back on with an addition washer to clear the stud more, and hold the pulley on properly.

Got it - Thanks

If you want to spend the money, here is the setup that I am going to be running. I am VERY close to firing this up for the first time!

I bought the full kit (Radiator and fans) from MonsterRadiators on eBay ( http://stores.shop.ebay.com/Monster-Cooling__W0QQ_armrsZ1 ). Total cost (with fans) was about $250 shipped! The radiator bolted right in with NO MODIFICATIONS! He does not have any listed right now, but you can contact him if interested. Each fan will pull 8.5 amps - it is worth doing the ZX alternator upgrade.

I am guessing that I should not have any cooling issues...

Here are pics of the radiator and fans and the clearance between the pulley and fans.
