I used a NPT tap - it was either 3/8 or 1/2" dia (its been
over a decade).
I simply tapped it for a threaded aluminum hex nut plug of
that diameter and
screwed it in tightly and its still there after over 10
year of running.
Not bad Ed. I'll
give you full credit in consideration for your aging brain
:-)
BTW, a good log and
search engine makes up for that. Imagine how I know this :-)
From my
log:
Tapped
the bypass hole in the water pump housing with a ½” NPT tap. This worked pretty darned well. Installed an aluminum ½” pipe plug, with
just a bit of high temp RTV on the threads.
