burping is a simple job - after the large amount or air is removed plug the cap back on and leave the engine running for about 10 minutes to let the system build pressure - then shut if off and top off the overflow container - leave the car alone for a while - you will notice any additional air is displaced into the overflow - there you go - job done.
Just check the overflow container for the next 2 days and top it off if low, do not open the radiator cap - If the system is air tight and the cap is good it will function perfectly normal.
If you want to make extra sure there is no air at all or if your car is a royal headache to bleed out then find a junked radiator cap and chop off the pressure head and install it on the radiator - this way any air will be expelled into the overflow container and coolant/liquid will be sucked back into the system. Make sure the cap's top seal is in good condition.
Do not leave this cap on the radiator - replace it with your good working cap once the job is complete.
