May 28, 200916 yr What is the purpose of this thing. When i had my green wagon with the bad t stat it didnt help cool the engine one bit when i drove it home. When my t stat is sticky in the white car it doesnt seem to keep the car any cooler until the t stat kicks on. If this thing is pretty much useless on keeping the car cool im dumping it. But since im trying to get my ac possibly working is this necessary to have or could i replace it with another electric one. Not that it will fit there, but i might make something work.
May 28, 200916 yr Is Guido an EA81 or EA82? This is for Guido, right? Anyway, you sould be able to find a good EA82 slimfan in the jy, an EA81 will probably be harder to find though. And if you have a sticky t-stat, then there is going to be reduced coolant flow in the radiator, so the extra fan won't do anything but blow more air over the engine And for these subaru engines, its enough in a pinch, but I would not recommend that you try it (trust me, you don't want to try it.) Good luck on finding a slim fan! (So I guess this means I recommend getting rid of your clutch fan ) Twitch
May 28, 200916 yr Got rid of the clutch fan on all my EA series cars. I also found a nice EA81 slim fan on ebay that I wired up to a fun button. Take the thermostat and throw it. Just my $0.02
May 28, 200916 yr Author Sorry EA82 twitch. But what does that fan half to do with the ac system since it obviously doesnt help cool the car. Ive been wanting to replace the t-stat for a while but once again its on the backburner. Edited May 28, 200916 yr by The Dude Abides
May 28, 200916 yr I agree with Evildead, if you t-stat is dying, chuck it. It'll cause you more problems having it in there, than not. Plus, going into summer you won't really need it until about september. It gives you just that much more time to get around to it. I would suggest putting a sticky note on your steering wheel about it. And the fan helps pull that much more heat off the radiator. It actually does something that the engineers designed it to do, amazing!! :-p But yeah, dump the clutch fan and the t-stat. You'll be better off without them. Plus you'll be able to replace that clutch fan with a better quieter slim fan! Twitch(ing)
May 28, 200916 yr Yeah those ol a/c fans sound like a damn jet plane when the clutch goes out on them anyways. Plus you may see an addition to 1HP gain!
May 28, 200916 yr or get a new propeller. That'd be funny. A propeller on the front of an EA82 wagon... Put fake wings on the doors The ss Guido! Twitch(ing)
May 28, 200916 yr The A/C fan is there to cool the A/C compressor - nothing more. They are not designed to cool the engine, but on a 100 degree day in traffic the compressor needs airflow or you WILL be replacing it..... and till you do you'll be the guy with his windows down and sweat beading up in that 5 mph traffic jam. GD
May 29, 200916 yr Author Im not doubting you GD but the fan is no where near the compressor, how can it cool it.
May 29, 200916 yr The ac condensor is in front of the radiator. The condensor is a heat exchanger; that is, it throws off hot air....right into the radiator. The second fan is there to get more air flowing through the radiator to keep the car from overheating while running at low speeds or waiting for the light to change while the ac is on.

May 29, 200916 yr The ac evaporator is in front of the radiator. The evaporator is a heat exchanger; that is, it throws off hot air....right into the radiator. The second fan is there to get more air flowing through the radiator to keep the car from overheating while running at low speeds or waiting for the light to change while the ac is on. isnt the condensor in front of the radiator and the evaporator in by the blower motor under the dash and the drier is along the shock tower, with the compressor on top side of engine next to alternator why do all these accessories end with "or" radiator evaporator condensor compressor alternator Eeor meteor band head more Edited May 29, 200916 yr by bheinen74

May 29, 200916 yr Author If i swaped the clutch fan for an electric fan i should be ok though for ac. right
May 29, 200916 yr There's a bit of misinformation here so let's get that cleared first- That fan is only on EA82 cars with a/c. It's there because the condenser increases the heat load on the radiator, since it increases the temperature of the air going through the radiator. However, this is not the case if your a/c is not on, so if your a/c doesn't work and the electric fan does work, you should be -ok- without that fan. Pull the nuts off the hub, let it drop under the car, and put the nuts back on to keep the pulley in place. Nothing done to the radiator will fix a bad t-stat, but just chucking it is not the answer. If it wasn't needed, no car would have one. It regulates the temperature of the engine by slowing the flow of coolant. If the coolant goes through the engine too quick, it won't pick up the heat, and if it goes through the radiator too quick, it won't dump the heat. Replace the thermostat with even a cheap one, and it'll be better. Oh yeah, I'd like to see you cool a squared off chunk of metal with a fan. The compressor is cooled by the fairly cool refrigerant it's pumping along with the oil in that system, and you'll be replacing your heads a very long time before you replace the a/c compressor due to overheat. If you put an electric fan in place of the clutch fan, I would put it on a relay. Signal the relay off the a/c compressor clutch circuit.
