Remove the drain tap on side of engine, there is a small passage that goes up
to water passage. Is always plugged with debris, will take a lot of fiddling to
get a stiff wire to get up into water passage. I always had the same problem
and gave up, however on the last rebuild I decided to figure it out, with head
off I dug out the top portion of passage to verify that it was really there,
then it took so time to bend wire right and up thru drain hole. It is there and
will drain just takes patience to work a wire up thru to clear passage.
