Seems as my degas bottle either cracked or hose is not sealing well. Did some towing, got her hot. About to buy new bottle and maybe trim the hose a bit. Tried a better hose clamp, still drips. Any words of wisdom? Can it be too much pressure in the system? Place to buy mopar parts? Thanks guys

You'll definitely want to get that changed sooner than later. There check rockauto.com (forum sponsor) or there is a bunch of Mopar stores online.
I think the pressure cap on these trucks is 22 psi, you could replace that at the same time.
If you don't use the premixed OAT coolant, remember to use distilled or deionized water to mix the coolant.

Doesn't look like a bottle problem unless the hose connecting nipple is cracked or has a surface defect.
I would start with refitting of trimmed hose and a new clamp.
And go from there.

Those spring clamps are near worthless.. Ny loosening in the hose material or degradation of the end results in problems. As well-stated above, pull, plug to save fluid, cut a teeny bit off the hose and replace the clamp with a screw-type stainless hose clamp that will hold.

Not sure where you are located, but I have a brand new Degas bottle that I'm not going to use. (Ontario)

Thank you for offer. Bought at rockauto, about 75 bucks, should be here tomorrow. Just need to pick up oat antifreeze and will do it. Will avoid dealer at all course, no flashing ECM for me.

Walgreens stores of all places carry a PEAK coolant that carries the correct spec number at a very reasonable cost.
Peak Global Lifetime

See attached spec sheet...

I would also start by replacing the hose clamp there , if it was about pressure above 21psi ,
the coolant would come out of the tube that starts under the bottle and drains down in tube
that looks like wire loom and ends at mid height on passenger side of the rad .

.
bits of info :
1-that bottle has negative pressure when cold , very hard to turn cap , some have even broken the cap ,
unlike regular vehicules you need to get a little temperature in the coolant for the cap to come off
easily . ... threads about that :

---
2- never mix OAT coolant with HOAT coolant , the resulting mix turns coolant to a jello like substance .
see images and imagine the whole engine clogged by that crap , ouch .
.
3- never use stop leak in an Ecodiesel :

.
4- never let the coolant go too low , you will have coolant in the bottle , but it will have started to go down
in engine and rad , next thing you know you overheat and bust a head gasket .

I had problems with those spring clamps 3 days after I bought my 2017. I had coolant leakage on the rubber hose that runs from the oil cooler to the transmission thermal regulator deal.

Stainless steel screw clamps solved the issue.

Every now and then, it could be weeks or months, my coolant will drop a tiny amount and then stay constant for a long time. Maybe a cup or less.

I have no idea where it's going or why except for perhaps a small amount gets by the bottle cap from time to time. I recall a post about someone having a psi gauge on a running Ecodiesel, and revving up the engine would momentarily cause a couple psi's jump over the rating for the cap.

And thinking about cars and trucks in general, it seems to me when I recall, my past vehicles would, over a long time, lose some coolant. All the problems with the EGR cooler is making me a bit paranoid and I "forget" these past things.

It's probably ok, but I'll keep an eye on it anyway!
