Hi Folks,

I have the 3.0L with 3,000 miles and up in Canada itís gotten cold (-2F).

Now when I start the truck the rad fans kick on at full rpm. Even when itís warm after an hour drive theyíre still roaring. Basically theyíve been running at full tilt anytime the truck is on since it got cold out.

I popped the hood and itís blowing frozen air right in the turbo. Makes no sense to me but wondering what your thoughts are before making a warranty appointment.

Also I noticed this truck has plastic louvres in front of the rad which are open. Are these supposed to close when itís cold out?

Thanks!

hmmmm seems like it should have shut those louvers, isn't that why they are there? If this place is like any other forums there should be a gm person reading ALL the posts for feed back to GM????? If they were nice they should reply back to you on the issue with your fans

My experience with 2016 2.8 duramax has been dismal and getting worse by the day. However that appears to not be the norm. From the press the 3.0 looks good but not great compared to f-150 and RAM. I would not buy another one personally.
