I had the whistle in my alternator, and the dealer replaced it. Much better. Dealer said there was a preliminary TSB?
Good luck. :chevy

Re: Alternator Whistle (redbob)
redbob,
If the noise you're hearing is in the A.I.R. pump, as your dealer indicates, then it should only be noticible for a few minutes at start up. How long the pump runs is dependent on the coolant temp.
Good luck.

I'd like to know this too. Mine has the same whistle and it is definitely the alternator(confirmed with stethoscope).

Re: Alternator Whistle (redbob)
The A.I.R. pump is electric...all you need to do is find and pull the fuse and see if it still happens. :yesnod:

Re: Alternator Whistle (redbob)
could you possibly be confusing the whistle with a supercharger? :D
