There are a lot of other bits and pieces concerning engine cooling systems that are not understood or misunderstood than what you mention but what you listed is good stuff. The part about no stat is great. I would however take exception to the 240 degree reference. The upper end might be 240 but 210-220 degree operating with a 195 degree stat which is most common today. Systems will handle 240 it but not an area of usual operation. One of my IC engine textbooks, which is old technology, has engine performance graphs relative to coolant jacket temp. Temperature at 180 degrees was the pivot point for efficiency. . We now run higher jacket temperatures for efficiency but mainly for emissions reasons. I put 180 degree stats in anything with a carburetor (unless feedback controlled) and factory recommended in everything else if for no other reason, just to keep the computer systems happy. We have a high bug count here right now. Dead bugs are plugging up our radiators. Another neglected area. .
