Resurrecting an old thread to crow that I have popped my AOS cherry as well. :dance:
PITA but with some patience it was accomplished. So far in two years of ownership Im up to; brakes, power steering pump and AOS. Water pump was covered by my extended warranty, otherwise that would have been on the list as well. Heres a pic of the diaphragm of the old AOS, hard to believe such a little crack created such a huge plume of smoke!!!!
