Squealing noise

[Anthonydpt]

I have a 2014 Sierra with 5.3. Ive been noticing a squealing noise coming from the passenger side of the engine compartment. Usually happens for about the first five minutes of running. Here is a video of the sound. Probably more audible through bigger speakers. Incredibly embarrassing noise. Any ideas? Ive already locked the exhaust valve open. No change with that.

 

 

 

Thanks!

I had a squeal /squeek, and thought it was brakes. Ended up being a U joint. Replaced the u joint and the noise went away.. it sounded to me like it was only coming from only 1 side of the truck from inside the cab. Hope this helps.

But being a 2014, i wouldn't think a u joint would be bad. But they don't make vehicles like they used to. If the noise speeds up with acceleration, it's a good bet though. . P.s. I didn't watch the video due to being at work, but mine was definitely a squeel.

Mine definitely is coming from engine compartment. It happens sitting still. Much worse at start up.

Are you running the Air conditioning? Could be the compressor bearing going bad.

 

Or maybe it's the actual accessory belt.

AC doesnt make a difference.

Well, I'm pretty sure I'm dealing with something serious. It has drastically gotten worse over the past couple days. I'm guessing I may need a new camshaft. This video is a much better represntation of what is happening.

Sounds like a belt issue

Ended up being a broken manifold bolt causing an exhaust leak. Dealer tried to blame it on me.

@anthony so what exactly ended up being replaced? 

Having same exact noise with my 2014 thought it was a belt but it’s not.
