Our 2003 Forester makes a dog-whistle-ish noise right after its shut off.

 

Not really sure how long it lasts but (never stood there and waited) but I have heard it still going a while later.

 

Anyone have a clue? A solution?

 

 

Thanks,

Is it a turbo forester?

Perhaps it simply is lonely for the open road, and wants to keep driving?

Maybe a small vacuum leak, maybe in the brake booster?

its saying WAAAAAAAAAAAAA DONT LEAVE ME!!!

 

 

its a vacume resevoir with a leak, my firts guess. Can be the booster, can be the small can that is there for the HVAC controls. Pop the hood next time you park then shut the car off, and listen

LOL!

 

 

It's a non-turbo 2.5X. Will do on the open hood/listen.

Take a spray bottle of water with you and spray the usual suspects while it is whining (or a can of WD-40, if you want). the part you spray that stops the whining, is your prime suspect the next time, until you find the part that stops it all the time. Then you know where the leak is, and can start on making the leak stop. . .

well you can also do this with the car running, as the engine rpm will change when it sucks in whatever your spraying.

Oooops, double-post. That'll teach me to do this when I should be asleep.

As has been mentioned already, this "sounds" like a vacuum leak or some sort of pressure equalization happening. Spraying a fluid at suspected areas may or may not help localize the culprit.

 

Since the noise is evident with the engine off, it's probably safest to work that way. First try to get a sense of the general area the noise is coming from. Then, a tool I've used that often helps to home in on things like this is a stethoscope, or something equivalent. A piece of tubing (vacuum hose, etc.) works well; just hold one end to an ear, and move the other end near the apparent source. You'd be amazed at how much easier it often is to pinpoint the sound that way.

sorry, couldn't resist.....

Ranger, do you pass those shirts out to the drivers that cannot keep up with you ?
