1983 240D Coolant Flush

[JEBalles]

I know there are already a million threads on this topic, but I can't seem to get the jist. Can someone give me explicit, step by step instructions on what to do? I'm not doing citric flush, just getting all the green stuff out and replacing with g-05 and t-stat replace. There are three bolts it seems: radiator, engine block, and block heater bolts from what I read. Which ones do I remove? How do I properly "burp" the system? I was told to run the engine up to operating temp and let cool all the way down with radiator cap off.
