Just to update this thread, we have new advice for the users:
  • Every oil change, suction out about 8 ounces (250 ml) of the power steering fluid and replace with Dexron VI ATF
  • Every five years (or so), when you replace the two lower oil-filter stem o-rings, also replace the o-ring in the power steering fluid reservoir cap
  • Likewise, every five years (or so), remove the T20 Torx bolt holding down the circular screen filter in the bottom of the power steering fluid reservoir and flush with gasoline (off the vehicle!) to clean the screen
