2. Wet the pressure cap gasket with water. Wash off any sediment from the sealing surface.
3. Install the cap to J 24460-92 .
4. Install the cap with J 24460-92 attached to J 24460-01 .
5. Apply pressure to the pressure cap by operating the plunger handle of J 24460-01 .
6. Note the rate of decrease in pressure.
7. If the cap fails to hold 103 kPa (15 psi), install a new pressure cap.
