nkx Posted June 8, 2005 Share Posted June 8, 2005 my clutch fan is pretty loud. i dont have extensive with subarus, so i dont know if its supposed to be THIS loud. you can hear the fan over the exhaust! i want to get rid of it anyway, because its killing power at the crank. i want to get a new radiator and a new electric fan. so should this thing sound as loud as it does? can i take it out without overheating the car? is the other fan going to be able to perform cooling duties on its own? exhaust.zip Quote Link to comment Share on other sites More sharing options...

SuBrat84 Posted June 10, 2005 Share Posted June 10, 2005 single electric fan in my 1984 ea81 keeps it cool just fine in 110 degrees. Quote Link to comment Share on other sites More sharing options...
Numbchux Posted June 10, 2005 Share Posted June 10, 2005 ok, I don't have any help, but rather a closely related question my electric fan doesn't appear to be coming on at all, not with it idling, though I haven't run it too long, it might be coming on while I"m driving it. Anyway, I know my T-stat is opening properly, but is the other fan supposed to come on at the same time? Quote Link to comment Share on other sites More sharing options...

If you have a clutch fan and an electric fan.. wouldn't the electric be for AC? In all my cars w/ 2 electric fans.. they only both come on with the AC running.

Phaedras Posted June 10, 2005 Share Posted June 10, 2005 Try switching out the fan blade. For some freakish reason it might be making that noise. Otherwise, all I can think of is some bearing in the water pump having gone bad. Try wiggling the shaft of the pump around a bit. If there's any sort of play, chuck the pump. (and put in a new one) Quote Link to comment Share on other sites More sharing options...
TahoeFerrari Posted June 10, 2005 Share Posted June 10, 2005 It might be the water pump. They often make a loud knocking sound when broken/failing. Try this: Remove the clutch fan and put the nuts back on (might need some washers) to hold the pulley on. Then run the car without the clutch fan for a bit. If it still makes noises, it's something else and not the clutch fan. Most likely the water pump. As far as running the car without it (and without a substitute electric fan) - I'm assuming you're talking about an EA82 here - , the other side (right) fan should turn on full time if the a/c is running OR if the water temp in the radiator at the thermo switch gets to around 200F. Whether thats enough cooling is something else. The EA81s without a/c only had 1 electric fan (on the left) similar in size to the right side EA82 fan and they were cooled OK, so I'd say as long as you don't run a/c you should be OK.

nkx Posted June 11, 2005 Author Share Posted June 11, 2005 how long would the car be able to go with a bad water pump? it hasnt overheated, its just obnoxiously loud. Quote Link to comment Share on other sites More sharing options...
subynut Posted June 11, 2005 Share Posted June 11, 2005 Mine was that way before I swapped it for an electric one. Sounds like the clutch in your fan has failed. It prolly has sized closed, so it's running all the time. Yes, very annoying. Part time solution? Turn the radio up! hummmmmm............remindes me of a song..............

Numbchux Posted June 11, 2005 Share Posted June 11, 2005 well, depend's how "failed" the pump is.....if it's leaking water out of the weep holes, then you'd better change it soon, mostly cuz then it leaks the coolant right onto the timing belt, and those belts don't like coolant (learned from experience). Well, haveing driving it for 45 minutes or so, at freeway speeds, then turning on the A/C for the last 5 miles or so, I popped the hood, and the electric fan was still not spinning, but the A/C was on fine...any ideas why this might be? I bet that's why my AC isn't cold unless you're moving..... Quote Link to comment Share on other sites More sharing options...
nkx Posted June 11, 2005 Author Share Posted June 11, 2005 Turn the radio up! no radio! i slapped an accessory panel in its place. maybe i can pull a junkyard fan until i get a new radiator and electric fans. Quote Link to comment Share on other sites More sharing options...
subyrally Posted June 11, 2005 Share Posted June 11, 2005 i might have a spare fan around here if you want to use it. ill have to go look for it though. Quote Link to comment Share on other sites More sharing options...
4WDFrenzy Posted June 12, 2005 Share Posted June 12, 2005 By the "other" fan.. do you mean a clutch fan? If you have a clutch fan and an electric fan.. wouldn't the electric be for AC? In all my cars w/ 2 electric fans.. they only both come on with the AC running. I think he is refering to the electric fan. Sometimes they come on but as far as I can tell mine only came on after the car had been idling for a while(Longer than 10 minutes). I was told by the previous owner that the electric fan never came on with the air conditioner. He said it was more or less a fail safe to keep the engine from overheating.

nkx Posted June 12, 2005 Author Share Posted June 12, 2005 i pulled the clutch fan off, i dont know how freely its supposed to spin, but im pretty sure its not up to par. i might crack it open today, and see if i cant grease it up or replace the ball bearings or something.

sregor13 Posted June 12, 2005 Share Posted June 12, 2005 I dont recommend running without that fan. Try some three in one oil or something like Quick Lube. I have had firsthand experience with two Subaru's in Wyoming overheating because they were missing a fan. What Year is this car again?

PoorManzImpreza Posted June 12, 2005 Share Posted June 12, 2005 the car will run fine without the clutch fan as long as you don't run the AC it will get HOT if u run the AC without it..FYI cars not equiped with AC only came with the electric fan..

(radiator lookin thingy), the compressor, etc, so i cant really turn the AC on. im afraid that the electric fan WONT come on if im out driving around, because i cant remember ever hearing it start. ill have to check next weekend to make sure its operable.

That should hotwire the electric fan to run all the time. Quote Link to comment Share on other sites More sharing options...
