After 18 min idoling and bubbling slowly, it finally opened the thermostat and fluid dripped a bit, l refilled back to full and am watching. I wonder honestly if l am still just getting trapped air out.
It suddenly pushed coolant up to top of Cap hole and over slowed a touch then dropped back to about normal. When l turned it off, it over slowed a little and then dropped back to normal. Its warm but not crazy hot.
