I was able to fill up and bleed the system a few times using the methods mentioned here. After that my idling temperature decreased and stabilized to around 207°.

I also did some troubleshooting on the auxiliary electric fan and discovered my low speed relay is bad. The high speed fan works but I never let the temperature get high enough for it turn on. I did test it using my old sensor and a heat gun, it worked fine.

Some notes/observations:

• The scanguage reads from the OBDII so the water temperature I am reading is from the sensor in the engine not at the radiator. Not sure what the differential is but at 227° the high speed fan was not on, I assume my low speed would have come on if it was working. Note that my dash gauge was at 12o clock but around 230ish jumped up. Supposedly the fan temps,at the radiator, are:
  195° low speed on
  210° high speed on

• For testing the Aux fan I shorted the terminals of the radiator sensor plug, you can do this to check both low/high speed. Additionally I plugged in my old sensor, removed from the radiator and used a heat gun which eventually turned on the fan at high speed.

• My upper radiator hose now feels like there is water flowing through it when at temperature BUT it does not feel full. Should the hose be full and hard to squeeze?

Thanks again to all for the help, I plan on some more testing today to make sure the system has no more air in it.
