2. Install the remaining sealing plate and tighten it securely.
3. Apply 40 psi (276 kPa) air pressure to the water jacket and
gallon of permanent type antifreeze. The antifreeze will
maintain this pressure for at least two hours to give the water
penetrate small cracks and its color will aid in detecting their
and antifreeze mixture ample time to work its way through any
presence.
cracks which may exist.
4. At the end of the test period, examine the cylinder bores,
air box, oil passages, crankcase and exterior of the block for
presence of the water and antifreeze mixture which will
indicate the presence of cracks. A
