‘22 ZR2 coolant smell

[landpilot]

So for the last few hundred miles or so, my truck has had a coolant smell when I park after driving for a hour or longer. I don’t see any obvious leak, and there’s no puddle under the truck. It also doesn’t appear there is any loss of coolant from the reservoir.

Anyone else noticed this on their truck?

I noticed it on my 2023 but it was after they put in new lifters.
Never had the smell before
At first they said it was burn off from the work.
But it was always there and I noticed the over flow tank was over filled.
I had it scheduled for service but decided to trade it in
