Losing coolant but pressure is normal

[Jam007]

Hi,
New to the site. For the last 2 months my 2017 Ram 2500 6.7 has been running odd with coolant. Gradual decrease in coolant level with no signs of residue anywhere. Normal pressure. Dealer service tested and normal. They replaced warrantied turbo actuator last summer.

Thanks for any suggestions.

has a vacuum been pulled on the system?

Pressure tested myself and the dealer but not a vacuum.

Did you check your oil for dilution . Milky color etc.

I'd drain the coolant and pull a vacuum on the system.. see if it holds. you should be able to tell where the leak is, if there is one.
