2019 Z71 Pulley/Bearing Noise

[Tahoecrewcar]

Recently had a noise when I would cold start my 2019 Z71 Tahoe. It sounds like a pulley or bearing but would like some opinions from the group. It does not do it every time I start the vehicle and once it warms up, the sound seems to go away. I've included a YouTube video so you can see/hear the issue. Thanks all!

Take the belt off temporarily and see if the issue goes away. If it does, you've narrowed down the possibilities. Also with the belt off, check that idler pully by spinning it to see if there is any play or noise.

run by the autoparts store or harbor freight and grab a $10 stethoscope, then you can narrow it down in a couple minutes. that noise should be easy to find with a stethoscope

89,000 Miles on the odometer.

This is a company owned vehicle, so I dropped it off at the dealership today to let them play with it. Hopefully, they can diagnose and replace whatever is causing the issue. The hard part is that the noise is not present all the time, so diagnosing could be "interesting." I've mainly noticed it on a cold start and then it goes away after a few minutes. My hope was to solve this before it worsens and leaves me stranded somewhere.

It's probably just pulleys or water pump. Nothing crazy

Winner winner! I just picked the vehicle up from the dealership and it was indeed a water pump and a tensioner pulley. They replaced both and commented that the belt was showing no wear and didn't need to be replaced even though I told them to feel free to toss one on if needed.

Good idea no need to pay for labor 2x for a 20$ belt
