I think the stat is ok, and the rad cooling is okay too as logically if either were poor the temperature gauge wouldn't return to normal in less than 5 seconds if the engine is revved to just over 1000 rpm, that aside, maybe a pump and belt change combined with stat change is a good preventive measure so all comments are appreciated.
On a negative side, I may have to let the Coupe go, very reluctantly, as the wife is really struggling to get in and out, her parent (old farts) can't even get in the back (bonus) so on the lookout for an accord v6 saloon or estate. If I can I will keep both of course 🙂
