Is it possible to stop the clutch fan while it's running? A mechanic did it infront of me, and said that he shouldn't be able to stop it while it's running. He told me that I need a new clutch fan... it this true?

I suppose he stopped it (secured it before the engine was started).

It's fluid driven and has a thermostatic valve inside that opens and closesto "couple" the clutch halves to turn the fan close to the pulley speed.

If you got more than 70K on it, it's likely to need fixin' anyway, check forthe cracks in the nylon blades and hubs too.

^word. but for the cost of a fan clutch and possibly a new fan, you might as well get an electric. just my opinion.

He was trying to make $$$ off of you... just get some electric fans and be done with it... (do it yourself)

heh, thats what most mechanics do. i believe doing your own work is funner but.. getting the electric ones will of course be harder to run than the OEM unit but.. in the long run, its welll worth it.

What a dumbarse.... When it's cold it should just spin freely with a bit of resistance and when it gets hot it should lock up..

Usually when they go bad, you can hear it because the clutch is locked at all times so you sound like a huge garbage truck...

Ya, I just changed mine couple weeks ago when I started hearing that noise (stock one lasted 142k miles). I got a new one at autozone for 35 or so bucks and I changed it out in serioulsy 5 min. The new autozone one sucks crazy amounts of air that when I redline my car it serioulsy sounds like a turbo spooling no lie LOL.
