New Truck Question

Hi

I just bought a 2010 chevy duramax 4x4. I love it. I noticed though after I turn it off it buzzes under the hood.

Is that normal?

Thanks
joAnn

let it idle down the turbo is still spinning give it a couple mins to cool down and relax after running it

You're hearing the Air Intake Valve move, It's normal.
