I don't recall this ever being an issue in the past.
Not a good sign ! If you did not swap it ahead of your trip, I would carry a spare (OEM).

I'm wondering what I should expect from my radiator. It is original and has never been touched, flushed or anything.
So you have the original coolant in it ! That would make me nervous also. Dexcool turns to sludge if it gets too hot. Really hard to clean out.
I do all of my own maintenance including radiator "flush". Drain, fill with fresh water and Prestone Flush chemical. Drive for at least 30 minute. Drain, refill with fresh water, drive for 30 minutes. Drain and refill a second time and a third 30 minute drive. Drain, fill with coolant.
The problem is, it is pretty much impossible to drain all the old coolant/water out of your system which is why I do TWO fresh water rinses. When putting new coolant in, I use 100% non-diluted. Use your favorite procedure to remove air. Check the strength. Adjust with water or coolant to meet the strength requirements.
