no: just that electric fans can be set to rotate both ways. you want the fans rotating so that air is pulled into the engine bay, pulling the air through the radiator into the engine bay.

i still havent found anything that compares the stock clutch's cooling capacity to an electric fans capacity ='( with a newer/bigger radiator it will be better regardless but id still like to know, for knowledge sake.

yeah i think so, mrnickleye uses 3 as he has mentioned before becuz he lives in the "desert", i used 1 on mine and it was overheating but where i live it can be real hot outside sometimes 2 so i had to add another 1......
but i think with the 2nd you will be allright depending on where u live.... just my 2 cents......

Some cars actually come with one on the front and one on the back, as a pusher and puller. I don't know why, I just think they would be better as just pullers. If you're getting a bigger radiator be sure to get a large enough fan. If you live in very hot climate I'd go for a dual fan. I just have one large fan, but like MrNickleye, I have an override switch so I can keep it running whenever I want during hot days. In fact I think I might add another fan. Hot weather sucks. As far as the stock fan, don't worry about it, I guarantee it doesn't come near 2950 cfm. Take the load off your engine. It takes a much smaller load to recharge your battery.

sounds good ill definantly go with the electric. This cooling system upgrade is starting to get costly heh. ;)

But im also relocating the oil filter and changing to 2 filters, redoing the lines, adding a oil cooler, redoing tranny lines and prolly use'n the old oil cooler for the tranny fluid

No Fan
 

Will an 87 NA supra overheat if the single electric fan is not functional? Thanks

Your fan for the engine is powered by the pulley not electric. I believe what you are talking about is for the a/c and not cooling the engine.

the stock fan's cfm is measured from engine rpm, it varies. in case you didnt know CFM means cubic foot per minute
so if the fan is rated at 5900cfm that means it pushes/pulls 5900 cubic feet of free flowing air and each cubic foot of air is 1 unit of mass

Ok
 

Please understand I have an NA NON turbo. The fan is on the radiator it does not cool the condensor. I can't seem to get a straight answer as to if the fan not working can allow the car to overheat, from what I have read it is tripped either by the AC or the Temp sensor. Mine does not work at all, works if I hook it up direct to power, I swapped fan relays from my other car NO DIFFERENCE. Where do you guys run wires into the cab so I can switch this fan, I see no easy openings on the firewall. I don't have fans on my condensor I have one big 8 inch electric fan shrouded against the radiatior on the motor side just like an older MK2 celica supra non turbo. Thanks for your help I broke the tang thingie off my thrromostat and now am about to drill it.

You should have a fan powered by the engine pulley. If you do not it must be aftermarket. As far as I know every mk3 came with a belt driven fan and not electric.

Of course I have a pulley driven fan, I also have an 8 inch electric fan on the radiator not the condensor.
