How do you bleed a Sporty?

Forum: 

I'm just in the process of re-building my Sporty after having it for only one week. The head gasket went on my way home from a private sale. What I need to know is how do I bleed the coolant system after the re-build? I don't want to repeat the process!

Also I'd like to know of ANY mods which can stop this happening again as it seems to be a common problem on here.

Thanks

Just fill her up and top up later.
