It's a minor drip leak and tolerable, so I live with it.
Detailed replacement video is on YouTube. Repair is too expensive and risky.
Radiator core sprung a leak and fogged up the cab. I was able to limp it back home and spent two days to replace it.

replace heater core
I had this too, had to pull out dash and change out heater core, about two days work, plus every time the heater was turned on it smelled like antifreeze inside the cab, that lasted more than a year.
