Why don't you just flip the bleed valve open & drive the car for a few days (or at least a few heating / cooling cycles) to get rid of any air bubbles in the system?
The pathetically vague temp gauge will not indicate the higher engine internal temperatures caused by air pockets
Getting rid of any existing bubbles is nigh on impossible without the bleeder valve being open - certainly not by undoing the pressure cap when hot.....
