Coolant: Testing and Inspection
Radiator Leak Test
LEAK TESTING PROCEDURE (ON VEHICLE)
^
Tools Required
-
J 24460-01 Cooling System and Cap Pressure Tester
CAUTION:
^
Under pressure, the temperature of the solution in the radiator can be considerably higher, without boiling. Removing the radiator cap
while the engine is hot (pressure is high), will cause the solution to boil instantaneously, with explosive force. The solution will spew out
over the engine, fenders, and the person removing the cap. Serious bodily injury may result. Flammable antifreeze, such as alcohol, is not
recommended for use at any time. Flammable antifreeze could cause a serious fire.
^
In order to help avoid being burned, do not remove the radiator cap while the engine and the radiator are hot. Scalding fluid and steam
can be blown out under pressure if the cap is removed too soon.
1. After the system has cooled, remove the radiator/surge tank pressure cap.
2. Connect the cooling system tester J 24460-01 to the radiator/surge tank.
3. Apply normal system operating pressure. Do not exceed 138 kPa (20 psi).
4. Watch the gauge needle for an indication of a leak. Examine all cooling system connections and components, including the radiator and the heater
core, for leaking coolant.
5. Tighten the hose connections or repair as required.
