Tid Bit. Is my radiator up to the task.

[Bob Dunahugh]

Many Many years ago. I wanted to know if my radiators cooling capabilities had decreased over time. Because of deposit buildup from leaving anti-freeze in more the 3 years. So, I pulled the thermostat out. Put the coolant that I had drained out, back in. Then went for a drive. If the temps are much lower. Then I knew that the radiator was up to the task.
There are many more areas to cover on this topic of cooling the engine/trans. As to the cooling of our GMCs. And those can be covered if there's interest. In short. Buy the things that you find you need. Not the things that you think you need.

Are you saying that the radiator and old fluid were up to the task because the thermostat was limiting cooling capacity?

Did you put the thermostat back in after your test?

The flaw in the test you did is is if the conditions are just at or below the capacity of the cooling system, then removing the stat will cause the
system temp to drop. Only because there is no lower limit set point This does not prove the ability to shed heat and prevent temp climb in severe
conditions.
