235 to 250 water temp measured in the correct location and verified with two gauges is quite hot. Too hot. 200 to 205 rolling and maybe 220 at a long stop might be typical or OK.

Infrared guns are a rough approximation... the factory location measures actual water temp which is what matters.

Next question is why is it so hot? Is it like that at idle? How about going down the road at speed? A few more specifics on radiator/fan/shroud setup would help diagnose.
