Coolant Spray on grill

[Ramwishes]

Hey all, having an issue with my 2012 Ram 1500.
We could smell burning coolant over the winter, the thermostat has been changed last fall.
Yesterday I noticed blue/green powdery spray mostly on the upper front grills, both sides.
I was thinking it might be the intercooler, but that’s mounted at the bottom front of the radiator so I’m thinking it would have to be the radiator, hoses or such.
Problem is I never see any puddles or anything and it seems to only leak when it’s warmed up and running, but it doesn’t overheat.
Any thoughts as to how to find this leak?

Pressure test the cooling system.The radiators are known to leak where the plastic tanks attach to the core.Go to your local Crappy Tire and see if you can get a pressure tester under their loan a tool program

You can buy (rent?) a kit to pressurize the cooling system to test for leaks. That may find the leak without having the engine hot and running.
