Guest HBDad Posted July 11, 2003 Share Posted July 11, 2003 I own a 2003 LL Bean Subaru Outback. Anyway, I often get a weird whining noise (think Chewbacca from Star Wars) when I first shut off the car after a long drive with the Climate Control/Air Conditioning on. It lasts about 3 to 5 seconds and then goes away. Does anyone have any clue what this might be? Quote Link to comment Share on other sites More sharing options...
Guest Strakes Posted July 12, 2003 Share Posted July 12, 2003 Could it be the cooling fan(s) that stays on after shutdown? I know that many times, mine stays on for a few seconds after shutdown. If that's it, then it's perfectly normal. Quote Link to comment Share on other sites More sharing options...
Guest 1 Lucky Texan Posted July 12, 2003 Share Posted July 12, 2003 If not the fans, maybe just a weird orifice tube/expansion valve issue as the pressure in the A/C system equalizes? let us know when you find out OK?

Guest tomrhere Posted July 13, 2003 Share Posted July 13, 2003 Could be pressure releasing from radiator cap too......Tom Quote Link to comment Share on other sites More sharing options...
marinesgt Posted September 21, 2003 Share Posted September 21, 2003 HBDad, I have a 2000 Outback 2.5 with the same issue. Good analogy by the way, Chewbacca. It happens when the ambient temp is above 85 degrees. It happens on up-pressure conditions, such as throttle lift-off at a stop light or passing gear acceleration or when it is above 90, when I turn the engine off. In the last example it will whine / groan for a good 15 - 30 seconds. Any ideas would be helpful. There is nothing on the Subaru tech site nor has the dealer found anything.
