Right then. I have taken the radiator off and gave the whole coolant system a flush through and also the new radiator took the thermostat out put it all together and bled it all up with the bottle method and touch wood everything seems to be ok atm. No overheating and no pressurising :-). Very happy
I'm going to run it without a thermostat for a week to make sure it's fine and then get a new one.
