Ok my heater is not working, so i think i have air in the line, whats the easiest way to get the air out of the coolant system

 

Turn the heater on high and hot and add coolant with the engine running. Then once topped off I manually throttle to about 2000 RPM and add coolant the rest of the way full and hurry and replace the cap before it starts to heat and pour back out then let off the throttle.
