If anyone damages (even scratches) his fan with the insulated screwdriver method, I will send him a fan for free

The cause for damaging of the alternator shaft splines is no different than those so called "soft" socket head screws holding down the valve covers.
The tool used must be inserted fully (overcoming any rust that has formed on the fastener), kept square and a quality tool should be used in the first place.

So.... I ordered the Snap-on tool (triple square head socket ) and managed to get off the bolt , but only after positioning the 24mm wrench against something immovable in the engine bay and putting a large pipe over the ratchet handle for more leverage. It finally broke free with a 'crack' and I though it was the tool again but thankfully not.
I proceeded to remove the outer pulley and shims and then tried to loosen the three bolts on teh inner pulley with my 5mm hex tool. Guess what? The tool broke. Yeesch! Who is tightening these bolts? Tarzan? (Yes, I tapped them with a hammer to loosen.) Anyway, I figure I have to go out and get a better hex head unless you guys have a better idea. Wow. I thought this was going to be fairly straightforward. Ha!

Jim,
Get a good quality Allen key and grind the end of the 5 mm completely flush. Since the bolts have a shallow head, you want maximum bite and insertion; grinding the end flush will do that.

Good luck with finishing the job!!! We all have battled through it......Hope it gets easier!!!
I got 36,000 miles out of my V-Belts and 12 years before pro-actively changing and 26,000 out of my A/C belt before it snapped after 8 years........
Car was third car for 14 years and daily the last 2 years....
What had been the experience from guys that seem to know?

Get good/high quality tool. Even Sears Craftsman can be crap. One 10mm allen socket I have was actually 9.6mm and immediately rounded many of these cheese-soft hex bolts Porsche likes to use.
When you put the 5mm (or any other allen/hex in), if it wobbles or feel loose, get another 5mm. A loose hex/allen key would strip the bolt easily.
