I flushed my coolant a few weeks ago. I went to run just water for the 3rd flush and filled the system from the cap hole and my system was all messed up, temp started climbing and it was gurgling and I burped it from the valve. When I put coolant back in it I fill the radiator from the upper hose, then filled the motor through the heater core from a heater hose. Covered the ends with my hands and got them on without much coming back out. Topped of the tank, bled the valve with the cap off till I felt warm water then bled it with the heater on. Long post I know. Maybe it helps? My car runs just under 1/2 unless I'm in traffic then it goes over 1/2. Not over 3/4. In the summer though a/c on and climbing it will get over 3/4 tell I stop climb or turn the a/c off drops quick with the heater on.
