I will try removing the thermostat and see what happens. I didn't notice any moisture at idle but it doesn't overheat when idling.

After filling it I let it idle and watched as the thermostat opened, the fan kicked on and it idled without getting too hot. Start driving it and it doesn't take long to overheat. There is a lot of pressure in the cooling system when it does. I'm going to test the coolant with a combustion leak detector. Hopefully I can rent one from a local parts store. If not I'll have to buy one.
