It has been suggested before , you need to pressurize your cylinder with 120 lbs or air.
Get a fitting or modify what you have, I knocked out the center out of the spark plug and welded a air chuck that fit my hose.
Fill the radiator flush to the top...If you have a leak to the water passage you will see bubbles.
Valves have to be closed when testing.
