Everything is back to normal. Temperature gauge is reading normal again. The only time it rise above normal operation temperature is first thing in the morning. It rises from 158oF to about 194oF, and drops back to 158oF. The thermostat is 195oF. I suspect that it must have opened which resulted in the drop back to normal operating conditions.
P.S. I did bleed the system again. Guess it must have helped. I am going to hold off on replacing OEM radiator. I will do it only as preventative maintenance in the next 2-3 months. I have never had a problem with the original factory radiator (no leaks or overheating etc....). My only motivation to replacing rad was due to gauge fluctuation.
