Run the engine with the radiator cap off, while you watch the coolant through the filler neck.
If you see bubbles in the coolant while it is running, you have a cracked head, block cavitation, or leaking head gasket causing combustion air intrusion into coolant system. IF, as engine temp increases, the bubbles increase to the point coolant is surging out of the filler neck.. certainly combustion intrusion, and always overheat will follow if the system is sealed. I suspect the original loss of lower cooling hose clamp was due to over pressure from combustion gas into coolant which simply blew off the hose at the weakest point, which happened to be a weak hose clamp, rather than the radiator hose. Further, I suspect all efforts since have not addressed the original issue, thus cured it.
