What plug is that?

When pressure builds up in the cooling system, any area that is weak would give way.

You should test the cooling system for excessive pressure which could possibly be due to a failed head gasket.

From the overheating, you may have damaged the head gaskets from constant overheating.

The thermostat may have been the original issue but has gone beyond that now.
