Fan clutch failed in on position

[Tools R Us]

Yeah but how do you take apart more than that? But I need to pull the flywheel out of the other housing. I am afraid i will need like a really good size hydraulic press to press the shaft out?

I haven't had them any further apart than that, don't know if the hub is threaded or pressed on? It sounds like yours lost the bearing, even if you did get it apart and got a new bearing, a new seal would probably be the hard part to get.

By the way the one that came out of the truck looks exactly like this one so I am confused about the POS comment, besides the oil being dirty.

Sorry, I saw Beno's pix and thought your old one was an original type?

All that for $122! Amazing.

So, you don't need to loosen the alternator belts? No chance of trashing any threads or getting the pulley catywompus?

Was it that much from CDan? now I do not remember,

Yup. Mine came in today.


Thanks Dan!

BTW - I could get the same price at the local dealer, but I'd have to pay 8% sales tax and spend an hour and a half of my time running to get it.

I owe Dan a

You are lucky that the fan clutch failed in the on position, as apposed to the off no workie position, like most of us.

I wonder. On the BMW e38 forum the "on" failure causes the fan to explode at high RPM, taking out the hood, radiator, remote oil filter, and many other fairly important parts. I saw one at Autosports Unlimited with a row of rusty bumps in the hood above the fan.

Most of the time the "on failure" is caused by the bearing locking up. Fans don't like full RPM's, when the bearing fails and the operator doesn't notice, then zings the motor they are known to come apart, violently! I have seen it on most brands of cars, the metal fans are the best, big holes in the hood where the blades came out!

This was pretty popular back when fan clutches first came out, some of the "old school" tech's thought they knew better and locked them with predictable results.

in the failed on position it sounds like you are driving a giant shop vac

I threw my new one in last night. Took about 15 minutes

tarbe, I didn't loosen any belts and the pully rubbing threads doesn't seem to be an issue. Once I put the nuts back on and tightened them down it all went right back into place. Oh, I did let loose the top 2 bolts on the fan shroud, push the shroud back then pull out the fan clutch between the shroud and the radiator towards the air filter side.

the pully is plastic

dam I thouight I had missed soemthing but went and checked my 96 is steel a magnet sticks,

[MaddBaggins]

Well, now you made me think, so I went out and took a magnet to it and it stuck. Ross and I both thought it was some kind of plastic the way it felt. Sorry for any cornfusion, I'm a ...

I'll edit my earlier post

the paint is thick, when I first looked at it I looked like it could have been plastic.
