Today is Saturday and they are likely closed for the weekend. Drill the hole 180 degrees from the dent that goes over the tab in the housing cover, and put the thing back in oriented correctly - like your first photo, not your last in the previous post, so the dent in the rim of the thermostat goes over the now ground off tab.

Check the hoses - they need to be firm when depressurized. Not hard as a rock, but they can't be soft either. Soft means they can be collapsed under certain conditions, likely during warm-up.

Does your system hold pressure? Once warm, or hot in your case, the system should be pressurized above atmospheric pressure, everywhere. Which should help in keeping hoses inflated. Once cooled down the system should depressurize.
