I'd like to thank everyone for their help on this.
Essentially, the car was overheating. It has over 144,000 miles on it.
I drove the car to warm it up and noticed even though it was overheating, the larger radiator fan was not working. I have a Bentley and a Haynes and proceeded with the diagnostics for the fans. I purchased a new fan and installed it and took the car for a drive. Oh Oh, it was still going above the 190 degree mark but not to the red line. In 6 years it has never moved off of 190 degrees.
I checked the lower radiator hose and found it cool even though the engine was warm. As I moved my hand up the hose to the thermostat it finally started to get warm, near the thermostat it was hot.
After replacing the thermostat (thanks for the info on no gasket sealant!), all is well.
I should have paid move attention to the temp gauge as I noticed once several weeks ago, it did move up about 10 degrees in temp but I paid no attention. It's our daughters car and I only drive it every month or so to see how it's doing.
Next time I'll know better.
Thanks again, Dermott
