- Wet the radiator cap gasket with water. Wash off any sediment from the sealing surface.
- Install the cap to J 24460-01
- Pump up the pressure to the pressure stamped on the cap by operating the plunger handle of J 24460-01
- Note the rate of decrease in pressure.
- The pressure reading should remain within the corresponding pressure segment of the scale for about 10 seconds.
- If the cap does not hold the corresponding pressure, replace the cap.
Remove the radiator cap.
