Coolant nipple on back of block-type 44-removable?

[Kneale Brownson]

I think the same basic nipple is used on my 20v, which looked to me to have
been pressed in.  Why not clean up the corrosion with a strip of emory
cloth?  you can "saw" it back and forth by holding both ends of a longer
strip (say 8") and pulling on them alternatively.  Change your hand
position and you should be able to get to all of the nipple.   I can't give
you a spec on the size, but I'm sure it's metric.  The hose between that
nipple and the heater valve is a molded one.
