A little about thermostats. Contrary to what most think, they do not heat up and open and remain that way. What they do is flutter, opening and closing depending on the temp of the water going past. They open and as the water gets cooled and comes back by, they start to close some, restricting the flow. Then the water gets hotter going by and they open more, over and over. Had a friend that insisted on driving after the police told him to wait in a nasty snow storm. After a while the Rad froze while driving. Too cold for the thermostat to open and the water, with some anti-freze, froze in the rad, busting it. This was a 6cyl. Ford mid-60's.
