INSPECTION

1) Remove the coolant filler tank cap, fill the coolant filler tank with engine coolant, then install the radiator cap tester to the filler neck of coolant filler tank.





2) Apply a pressure of 122 kPa (1.2 kg/cm2, 18 psi) to the radiator and check the following points:

- Leakage from the radiator or its vicinity
- Leakage from the hose or its connections

CAUTION:
- Inspection must be carried out at the side of coolant filler tank, not at the side of radiator.
- Engine should be turned off.
- Wipe engine coolant from check points in advance.
- Be careful of the spurt of engine coolant when removing the radiator cap tester.
- Be careful not to deform the filler neck of the coolant filler tank when installing and removing the radiator cap tester.
