Hose connections for leaks.
^
Surge tank cap for loss of pressure using cooling system pressure test adapter and cooling system pressure tester. If the cap does not hold the rated
pressure, replace the surge tank pressure cap.

Make sure that the correct cap is being used.
PRESSURE TEST
CAUTION: Pressures above 138 kPa (20 psi) should not be used when testing the cooling system. Pressures over 138 kPa (20 psi) will damage
the radiator.
1. Inspect the connections for leaks. Repair as required.
2. Remove the surge tank cap.
3. Attach cooling system pressure test adapter and cooling system pressure tester to the surge tank.
^
Follow the instructions supplied with cooling system pressure tester.
4. Build up pressure to no more than 138 kPa (20 psi).
5. The system should hold the pressure for about two minutes.
