Once it’s warmed up and the thermostat is opened, I rev it with the cap on. If you rev it hard with the cap off you’ll get coolant everywhere. I find it shoves any air out that way. A few blips of the throttle should force coolant through all the pipework. You don’t need to go mad.
 
Water boils around 100c at sea level.
With a 14psi cap that increases to around 120c. If it's 50/50 antifreeze then it rises further to around 130c. If i recall
 
The pressure and also the running temp depends greatly on the level being correct in the expansion tank. It will run a few degrees warmer if it's even a bit low
 
I believe I followed the RAVE method:

- Drained as much as I could via rad plug
- Slowly filled expansion tank with a hose on a small stream
- Started engine, monitored level, waited for thermo to open
- Stopped engine, waited for it to cool, topped up expansion tank again.

I believe that's how it's done it RAVE? Maybe without the garden hose.

Oh and I also blew through the return pipe to clear it
