fan making some wierd noises

[carbed87]

i just have my oem fan on, but the other day i noticed that when i rev it up past, oh i dont know, 2k, the fan starts howling all loud. i got it to stop by popping the hood and spinning it by hand the other way (i think) and it didn't make the noise.... that was yesterday, and i had to do the same thing today. could someone tell me whats going on with it. thanks oh, and happy thanksgiving

you don't need a new clutch fan nows the time to upgrade to a electric fan.

 

[sjhm9102]

cause a new fan clutch is about 70 bucks

yeah, i have a3.8 tauras fan in my garage, but i havent really looked into mounting it and stuff. i guess that'll be something to do this weekend

 

[carbed87]

so would it be ok to drive around like that. im guessing the howling just means that the fan is blowing the whole time right.

yah sounds like the clutch mechanism isn't working. I would check to make sure all the bolts are tight however. But i'm sure its safe to drive like that provided it is succured properly.

How easy was it to spin the fan the other direction?

well, it'll get really easy sometimes, then it'll tighten up as if it was threaded, then later break away and be loose again. i noticed that if it's loose like i explained, it doesn't howl. however i think this also means that the fan straight up isn't working because it looked like my temp gauge started to clib a lot. say, would this sort of thing suck any power from my car. i dont know if the "placebo" effect, but it seems like from second gear up, it doesn't seem to have as much mid-range as it did.

either way. i AM throwing that tauraus fan on. would my local parts store carry a "wiring kit" with all the necesary relays and everything.

once again, thanks for all the replies on such a lame question lol

I gotcha. The clutch fans use silicone in a viscous coupling. A bimetallic spring regulates the flow of fluid (so it locks up when the clutch gets hot). You might find fluid leaking around the clutch hub when you remove it.

In any case, your plans sound great. You can make a cheap controller from the parts store work. Post up if you have AC and we can get you schematics.

The best way to control it would be a Dc Controller.

Good luck.

 

[carbed87]

yes, i do have ac. and schematics would be GREAT! thanks hissin

Depending upon what controller you use, this diagram might help.

Mr. Smith has a pretty good write-up that might help.

EDIT: some folks have said this article is helpful.

Good luck.
