Until you can put a real number to the temperature its just guessing.
Mechanical temp gauges are inexpensive.
Not boiling over is a good indicator of not having a problem, or not a serious one.
Got a reading with a heat gun. Running 220-225 in traffic. It’s okay when nit in traffic. If I go to 22” radiator will I have to change hoses and where the transmission lines go in?
