Hello all!
2007 Tahoe LTZ has ~ 281K miles on it.
I was in my room getting ready and my wife was leaving for work...I heard her start up the Tahoe and I immediately heard a loud whistling noise coming from the vehicle. I was in the house and heard it through our thin windows, lol. So upon start up it was pretty loud, then it kind of died away, but as soon as she backed out of the driveway I heard it a little more, then when she drove forward and accelerated away, I heard it again and its consistent with vehicle RPM.
Almost two weeks ago, I changed the air filter and removed and cleaned the MAF. I did do a test drive afterwards and did not hear any noise that was out of the ordinary. I will check the air box and MAF and air intake connections when she gets home.
But it def. sounds like air leaking, and its def. a whistle.
I do have the original water pump still in the vehicle. Can a failing water pump or power steering pump or any other accessories along the belt drive make a whistling sound? This is def. not a WHINE, its a WHISTLE.
I just replaced the both main drive belt and a/c belts and all tensioners earlier this year in the spring.
Thanks in advance!
