Tools Required

Caution: To avoid being burned, do not remove the radiator cap or surge tank cap while the engine is hot. The cooling system will release scalding fluid and steam under pressure if radiator cap or surge tank cap is removed while the engine and radiator are still hot.

1. After the system has cooled, remove the surge tank cap.
2. Wet the surge tank cap gasket with water. Wash off any sediment from the sealing surface.



3. Install the cap to the J 24460-92 .
4. Install the J 24460-92 to the J 24460-01 .
5. Use the plunger handle of the J 24460-01 in order to obtain the pressure that is specified on the cap.
6. Note the rate of decrease in pressure.
7. Determine if the pressure reading remains within the corresponding pressure segment of the scale for at least 10 seconds.
8. If the cap does not hold the corresponding pressure, replace the cap.
