Also, if you R&R the alternator, replace all of the idler pulleys, too.

I know of three Boxster fires caused by idler pulleys that seized and caused the serpentine belt to catch fire.

When I bought my 2004, she only had 25,000 miles on her. I replaced the serpentine belt at that time, and one of the idler pulleys had already started to fail.

Good luck.
