Your picture shows no shroud, BIG no-no, and your looped together heat hose is returning hot water right back into the block. You basically need more airflow through the radiator, and fix some of the "hacking" there
I should’ve looked more closely at the picture. The lack of a fan shroud by itself could be causing the issue.
Really, 200+ degrees is not unusual in traffic. And that assumes your temp gauge is dead on. If it stays under 220 I wouldn’t consider it a big issue. And the missing shroud really hurts fan efficiency.
