2019 Magical disappearing coolant

Check around the radiator cap on the surge tank. Look for a dry white cakey substance on the sides and bottom of the tank.
When/If you have a small leak up front like that its hard to see a puddle as the liquid gets blown off by incoming wind and dries/evaporates so you don't see any puddles.
Should still show up under a dye test though.

I had a pressure check done on an old GMC I own. They removed the radiator cap and installed there fitting to the spout to add the pressure. My leak was the heater core. The cap function was not checked. Send in an oil sample, if there is a leak, they will know. Easy to see the chemical change in sodium and potassium.

Did ya ever find out where it was? I am having the same exact issue on my 18 and had it on a lift, looked everywhere. If it is a small leak I am guessing it disolves before I can find it!

Any idea what this was? Having the same issue on a 2017.
