Burping a cooling system

[Quadcammer]

lift ass end of car as high as your jackstands will allow. Open the bleeder and coolant cap.

Run the car, revving occasionally, holding at 3k rpm for a while, repeat a few times.

If you still aren't getting consistent coolant flow, you may have another issue.

PS, perhaps you want to leave the heater valve open as well..
