Thanks, Steve. 

Just for the sake of having the info here in case the other forum tanks sometime down the line... this was posted over there today:

The cooling system on the 2.0L Solstice/Sky is completely different than anything you may of seen in the past. Drilling a hole, of any size, in the thermostat will not correct the no heat – over heat condition. When your DIC is reading 245 deg, turn on your heater blower. If cold air is coming out of the heater, the problem is the result of air in the cooling system that will not purge. In every case I’ve reviewed the cooling system was opened on a warm/hot engine when the engine was turned off. When you open the coolant recovery system on a hot engine, you can hear the air being sucked into the system.

This condition can be corrected by installing two check valves in the cooling system. The information and part number for the valves will be available to your GM dealer sometime towards the end of December.
