With bleeder valve open, the engine must be off. After coolant flows out of bleeder valve, tighten it and start engine without radiator cap. When coolant level at radiator neck drops, top up. Repeat until coolant stabilises and close radiator cap.
Run engine till radiator fan comes on and when engine cools down, check coolant level again.
