Hi all,
Anyone have an issue with your 2017 Colorado diesel exhaust manifold leaking? Started hearing a whining, belt like sound, was able to take in a week later, and they diagnosed it as the above issue.

New vehicle...???
Thanks,
E

Thanks for the link! Interesting.
Please give us an update on what the dealer did to fix it. Thank you. I will have to check mine for that bolt.

Will do! It's going in the shop next week.
Well, You got it buddy! 4 manifold screws were extremely loose, so they applied screw glue and tightened them up! Problem solved. Glad it was that simple of a fix. Cheers, and thanks for your input

So, I have another update on this issue!
Just had it back in the shop for the same sounds coming from the vehicle, and this time they informed me that the manifold is warped and needs replacing. Part is on order...!!
Anyone else hear of that?

Also, sorry for the very delayed response, Rockcrawlerdude, no pics taken
Having the same issue, Only after a few weeks of cold weather here in MN.....have to bring it in....Also have a weird burning smell (not in regen) dealer said it is normal....
