Temperature sensor in engine block

[DonSTP]

Curious if anyone's removed the temp sensor in their engine block if they had to drain the coolant from the block first? 

Thanks -

There aren't any temp sensors in the engine block - only in the cylinder head or intake manifold. You need to drain enough coolant to get the level below that of the sensor before removing the sensor or you'll have a real mess to clean up.
