Burping the radiator/cooling system

I need to put coolant into my E38 howver I was told I need to "burp" the tank before adding? Meaning I need to make sure there are no air bubbles. So if anyone knows how to let the air out could you help. Thanks.

-Fill up the coolant in the expansion tank and let the car idle, preferably with the front of the car up on an incline, and close the expansion tank cap.

-Let the car idle for a while and get warm.

-Open the bleeder screw (next to the cap) slowly until coolant comes out of it. If you see bubbles coming out of it, then you do have air in the system. If after a few tries, no coolant is coming out of the bleeder, then open the cap (VERY SLOWLY) and add more coolant to the system.

-Do this a few times until there is just a steady stream of coolant coming out of the bleeder screw (no bubbles).

-When only coolant is coming out of the bleed screw, turn on the heat and see if hot air comes out, if it does then you are finished.


Do this a few times over a few days and you should get all of the air out of the system. I have never had a problem bleeding air out of these motors.
