Once you have done that take car for a good run with the OBD on 19 then 7 so you can read the temp as you drive once it get to the 92 -96 if it does open the A/C on HIGH then watch the reading go down.

Once back home let engine run on tick over again watch the reading if fluctuation then use the bleed screw again.

Thanks Arctic.
Yes, header tank was raised as high as it could go, bled through FBH bleed screw and then engine run with expansion tank cap off for a while until temp reached 60, before putting cap back on. But I’ll redo at the weekend anyway, using the bleed screw with engine running.
