I set out to do a more thorough cleaning of the reservoir threads, so I removed the plastic cover at the oil and coolant station. I saw that the ventilation (purge) valve top had a light yellow corrosion build up on it. So, I cleaned it off and vacuumed out the residue. I figured that something must be loose to cause the corrosion. I checked the nuts on the top of the valve and found that a few were relatively loose. I carefully snugged them up.
The next morning I did the pressure test. No pressure loss.
I took it out for a drive yesterday afternoon. Mid 70s air temperature. The engine coolant temperature improved from historic marks and stayed consistent. Very pleased.
This morning I see that there is still condensation on the underside of the rear trunk. Plus, I did notice the smell of coolant in the garage after my 15 return evening drive.
Improved situation, but I have to do the additional leak checks that others have suggested.
