Well, to me it sounds like your battery is weak.... seems like a slight hesitation on start like it is not getting the CC Amps it needs.

This could be causing stress on your belt? Sounds like the belt to me.

Definitely from the engine/front engine area.

Do you have a warranty?

Battery is not even 1 year old, 85k miles so no warranty. I guess ill change the other two smaller belts and see, Keep you posted.

Hmmm... well there seems to be some sort of drag on the engine the way it lugs down on first crank.

Hopefully someone else can chime in soon

Here is an easy way to determine if the belts are causing the problem:

1) Take belts off

2) Start engine

Note: Do not run the engine for more than 30 seconds at a time without the belts on (water pump).

Well, took out starter cleaned it greased the hell out of it and noise is gone!

was it for sure the starter causing that start up squeak? I’m having the same issue on a 2016 silverado 1500 5.3

I, myself, seem to be having a "squeaking" noise coming from the belt area in my 2015 Silverado 1500. I've included a link to a video so you can hear it. Not too sure what it is, but any thoughts or solutions to try would be very helpful! *** Side Note *** If you own a 2015 Silverado and haven't replaced your Vacuum pump, I'd highly recommend replacing it yourself before it goes out. Seems to be a common problem with this year model, yet GM won't put a recall in for it. If you're unlucky enough for it to go out while you're driving, you'll lose your ability to stop. You'll have to have it towed in, and GM will charge you roughly $800 to get you a new one. -_- ***

I had both a startup squeak and also lugging on start on my 2014 6.2

The lug ended up being the starter. I originally thought battery too but after I replaced the battery and the starter began to smoke it confirmed the battery was not and issue...

The squeak was the bearings in the alternator.

Hey bud, did you figure out a fix? I have the same exact thing with my 2015.

I haven’t yet. Should have some more free time later this month to try to dig a little deeper though.

Thanks bud.

Anyone had a solution to the squeaking? I have the same issue on my 2014 Silverado 5.3L. Changed the serpentine belt and it still squeaks. Anything else i should try?

Gonna revive this thread, I’m having the same issue upon startup. It clears up within 5-10 seconds, however when I pick up rpms going down the road it will start squeaking again..

I also have this same squeak on my 2015 5.3. I cut out the flapper valve and put on a Flowmaster. Eliminated v4 to v8 squeak, but I still get the squeak on startup. Anyone know what to use to grease the starter as someone mentioned before? I started my truck while laying underneath and the noise seemed to be coming from the starter.
