Coolant leak

I have a 2015 F250 diesel with 165k. Just recently noticed level was low and I have to keep adding coolant. I do not see any leaks in the coolant system. Anybody know what my next check should be. Note: Its the primary system not the smaller one.

If you see white exhaust then your coolant is getting into the cylinder.

A coolant system pressure test will show if the system is holding pressure or not.

follow the hoses coming off the degas bottle. There is a T in line there that has been known to leak a bit in the past.

Any smell of coolant? What about white residue around the cap?

Look on the main radiator along the driver's side seam where the plastic end piece is crimped to the aluminum section. It's a great place for a seep leak that will never hit the ground, but you might smell coolant in that area when it's hot.
