I have bought a new ECTS from my local parts store put have noticed that it doesn't have a connector on the end, its just simply a probe with a large thread on the engine side and a small thread on the connector side.

Second stupid question; If I were to replace this sensor wouldn't coolant come pouring out? If so would this not introduce a pocket of air in the system? I haven't had to work on the cooling system yet and I wouldn't know where to start if I had to bleed it.
