Tools Required

Notice: Pressure above 139 kPa (20psi) should not be used when pressure testing the cooling system. Pressures over 138 kPa (20) psi will damage the radiator.

1. Inspect the connections for leaks.
2. Repair the connections as required.
3. Remove the surge tank cap.



4. Attach the J 42401-02  (3), theJ 42401-04  (2), and the J 24460-01  (1) to the surge tank.

Follow the instructions supplied with the J 24460-01 .

5. Build up the pressure to no more than 138 kpa (20 psi).
6. The system should hold the pressure for about 2 minutes.

•	If a measurable amount of pressure drops in less than 2 minutes, test for a leak.

•	Mark the leaking area. Remove and replace the radiator if necessary. Refer to Radiator Replacement .

Tools Required

1. Inspect the hose connections for leaks.
2. Inspect the surge tank cap. Use the J 24460-01 and the J 42401-04 in order to test the cap for rated pressure. Replace the surge tank cap if the cap will not hold pressure.
3. Inspect for damage or debris on the gasket in the cap and the inner sealing surface of the filler neck.
4. Use the correct cap.
