Bradley,

The ones that I have changed have been the threaded type as used on the 1.9L
and the Syncro.  With these, I had everything ready to go before I removed
the sensors.  By plugging the orifice with my finger between removing the old
and threading in the new, almost no coolant was lost.  Of course, you want to
do this on a stone cold engine.
