Thank you for giving us more information about your system and how it behaves.
The warm radiator confirms you are circulating water. You are over spinning the water pump, which is good. You have a 180° thermostat which I personally believe is the correct value. You say the temp sender is located in the “recommended location”, which I trust is on the front of the engine block.
honestly, all I see are some high temperatures. those are just numbers, and absent any actual performance/durability problems, the numbers just serve to cause concern.
you noted your temperatures rose after you let it idle in your garage, which is probably not a good thing.
despite you having a good radiator and good fans, it appears there is not enough air moving through the radiator at low speeds.
I would think that you would have a aluminum “box” shroud for both of the sucker fans. If you only have sucker fans mounted, then a large part of your radiator is not seeing air movement unless driving at speed. If that is the case that needs to be addressed.
I would like to know what temperatures you see after idling in your driveway for 15 minutes.
most sources indicate an operating temperature of 220° is not out of normal.
honestly, all I see are temperatures that might “appear” to be too high.
let me share a little bit of pantera service history. In the 1970s most cars just had temperature idiot lights, not an actual gauge. Many Pantera owners’ first experience with a temperature gauge was their pantera, and when they saw the needle swinging “too far” to the right they thought something was wrong. So many cars were coming in for cooling system service that Ford actually came out with a technical service bulletin to correct the problem. After the TSB was performed, the gauge needle did not travel as far and the owners were satisfied that the TSB had solved the problem. What was the TSB fix? The technician soldered a resistor into the gauge sender circuit, changing the resistance and thus changing the action of the gauge. Moral of the story? A number is not necessarily indicative of a cooling problem
