Leave the coolant cap off, let the engine get to operational temperature and see if bubble come up into the coolant reservoir. Compression testing of
the cylinders will tell you more ....Pressurized coolant system is so the boiling temp is higher when pressurized. Releasing the cap when system is pressurized it's normal theses bubbles.
