Chirp at start

[Blackcar]

I have 2017 Yukon Denali that when you start there seems to be a slight belt chirp I have noticed this for awhile doesn't get worst stays same just wondering if anyone else noticed this vehicle has 17000 miles on it bought new.

Have you had dealer look at? Thanks

could be the belt tensioner, take the belt off and spin the tensioner see if it makes any noise, spin anything else to check as well, then start it up for a second and see if the noise is gone. sometimes the tensioner may only make noise under a load.

Will do Thanks for suggestion.

I looked at tensioners and accessories didn't see anything . Had to take truck in for shutter in transmission for which they had to change trans fluid while it was there had them address chirp they also didn't find problem.

looked at it? or actually took the belt off and started it up without the belt on and/or spun the tensioner by hand? did the chirp occur with the belt off?
