      My 1500 LM2 Duramax makes a lot of clicking and whirring under the hood after shut down. I don’t think there’s a problem. I’m sure it’s part of a normal sequence. But what is it exactly… does anyone know? Thanks.

      according to the manual it is closing and opening dampers and turning things off. Mine does the same thing and the manual does mention this.

        I will admit I haven’t read the manual cover to cover. Just a few areas where I had questions. I’ll have to look closer. Hoping it talks about specifics. But, it is just an owner’s manual. Thanks.
