Did you burp it after replacing the thermostat?

51, Igor makes a good point, you may have a trapped air pocket, and that may cause an interruption of the coolant flow, which may have heated up and caused the pipe to give.

Questions I have. How far was the car driven during and after the overheat was discovered? Is the engine now toast? These little engines don't take well to any overheating situation.
