Radiator Cap: Testing and Inspection
^
Tools Required
-
J24460-01 Cooling System Tester
The vehicle is equipped with an aluminum radiator. Use the outlined instructions in the Aluminum Radiator Diagnosis section in order to remove the
cap:
CAUTION: As long as there is pressure in the cooling system, the temperature can be considerably higher than the boiling temperature of the
solution in the radiator without causing the solution to boil. Removal of the pressure cap while the engine is hot and pressure is high will cause the
solution to boil instantaneously -possibly with explosive force - spewing the solution over the engine, fenders and the person removing the cap.
1. Remove the cap.
2. Wet the radiator cap gasket with water.
3. Wash off any sediment from the sealing surface.
4. Install the cap to J 24460-01.
5. Use the plunger handle of J 24460-01 in order to increase the pressure as specified on the cap.
6. Note the rate of decrease in the pressure.
7. The specified reading of the pressure should remain within the corresponding pressure scale for more than 10 seconds.
8. Replace the radiator cap if it does not maintain the pressure for more than 10 seconds.
