Noise From Cooling Fan ?
I think that’s where the noise is coming from. It sounds like the fan is rubbing against the housing. Is it my imagination?? Can I actually see the fan moving up and down?? I could prove my hypothesis by disconnecting the fan belt and running the engine for a short duration to see if the noise stops...RIGHT??
Question 1. What's the trick to removing the fan belt? Simply un-bolt the pulley? Question 2. If this is the sourc e of the noise, what's the solution? Bearings? New alternator?

Sounds like classic symptoms of alternator bearing failure. Lots of threads on this.
If you're going to run the car without the belt (and I would not recommend that you do do), only do it for a few seconds. Good luck!

Hi Larry,
You could go right here to find out about fan belt removal - I had to change mine on the second day of ownership. Keep track of the shim locations. http://www.pelicanparts.com/techarticles/911_fan_belt/911_fan_belt.htm If it's rubbing, the scrape marks will be very bright. Some shops specialize in alternator/starter repair, however, I am not sure if they'll handle Porsche alternators.
