How do I "burp" the coolant?

[Crazy E]

Hey guys, I just wanted to know how to burp the coolant on my 1st gen. I changed the headgasket and had to drain and refill the system, and I heard before that it is a good idea to burp it when you fill it up.

How is this done? Is it really necessary? How do I know its full?


P.S. yes, i know its strange I could change a headgasket but not know how to burp/fill coolant....

idle the car with the radiator cap off so all the air bubbles can escape.

Just fill it and run it. The system will work the air out after a few heat/cool cycles.

You can also crack the radiator cap and squeeze the lower hose, then tighten. 3-4 times ought to do it.

Whenever I drain or do anything with the cooling system........and have to refill it.....
I grab the lower rad hose and squeeze it while filling....you can pump the air out by doing this and should remove most of the air.


I do this on everycar I work on and it seems to work well.
