Q: Car over heats

The car overheats but when I bleed the bleeder above the water pump it returned to normal. When the engine is cold and not running if you remove the radiator cap you will have a vacuum that sucks the coolant and Air into the system. No oil in the coolant no cloud of white smoke. If it runs at idle with the radiator cap off the thermostat will not open and the coolant reservoir overfills. It runs with no problem as long as I keep bleeding the bleeder above the water pump every 10 minutes or so. Pressure testing the coolant system to 15 PSI for 30 minutes. It held pressure. I tried to block tester with the liquid, but the Reservoir would overfill before I could complete the test. I have changed the thermostat and I change the water pump.

My car has 137000 miles.
My car has an automatic transmission.
