 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.

Thanks for the heads up! I ordered the extra parts. They will arrive next week and I’ll save the install for a rainy day sometime soon.
