2007 Rav4 cooling system overheats. Replaced water pump and thermostat. Still

What is your question?

My 2007 Rav4 Still overheats. Maybe air pocket blockage in system? Special way to add coolant?

What makes this problem better or worse?

When it overheats and the dash temperature needle goes to red zone, I rev the rpm's to about 4000 rpm and after a little while, the temp drops. I have to do this every 4 minutes if I'm driving the car.
