There is a write up at

If your coolant is more than a few years old I suggest changing before bleeding. It is only a little more work but quite a bit more mess to change the coolant.
I used a pressure tester to bleed the coolant, then started the engine and let it get to operatinging temperature at which time I turned on the heater so the all of the cooling system was active then opened the bleed valve again very carefully to allow the remaining bubbles to exit.
After researching coolant I decided to use Zerex G-05 because it was the right stuff and available locally. Next time I will use the premixed version to avoid all question of whether the right kind of water was used with it.
You can see the bleed valve in this picture where the top radiator hose connects to the engine directly above the blue clip.
If you change the coolant, it is a good time to change the HCV, or at least a much better time than on the side of the road.
