Hi=20 Thomas,

I used a NPT tap - it was either 3/8 or 1/2" = dia =20 (its been over a decade).
I simply tapped it for a threaded = aluminum=20 hex nut plug of that diameter and
screwed it in tightly and its = still=20 there after over 10 year of running.

Not bad Ed. =20 I'll give you full credit in consideration for your aging brain=20 :-)

From my=20 log:
 
Tapped=20 the bypass hole in the water pump housing with a =BD=94 NPT = tap.  This worked pretty = darned=20 well.  Installed an = aluminum=20 =BD=94 pipe plug, with just a bit of high temp RTV on the threads. =
