2012 Cascadia Cold water leak help?

Hey all!!
I have 2012 Cascadia and since the weather has changed here on the east coast going into the 40s at night my truck has sprung a cold water leak somewhere in the front around the radiator.
It does not leak while it is running but when I park it and come back in the morning there is a new antifreeze spot on the ground.

my guess is that it is a hose with a hole that is swelling when the motor is hot and shrinking and leaking as it cools over night. But I do not see any signs of the leak when I go to investigate.

Has anyone ever had to deal with this issue. Again the leak is a In the area under the radiator. It is a dd15 motor has 640k on it.

 

Bingo! Checked the lower radiator hose and it show coolant leaking. The upper and lower clamp were a little loose. Snugged them up and will have a diagnosis of the fix tomorrow once I go out. Will let you all know if that fixed my problem. Safe travels.
