Is the sensor in actual thermostat housing ( the lower part) or in the top half?
The top halfves are probably still cheap, the the lower part is a rare part and expensive if you can find one
Forget soldering, although you may be able to get it alloy welded and then re tap the hole correctly, if its not too corroded
Helecoils are no good for threads that seal on the thread
You could try building it up with Devcon and remachining. This worked for me on restoring a water pump housing with an ally housing on a RRC V8
another thought- enlarge the hole and tap it to suit a larger reducer?
