  2. Apply a pressure of 122 kPa (1.2 kg/cm2 , 18 psi) to the radiator to check if:
    1. Engine coolant leaks at/around radiator.
    2. Engine coolant leaks at/around hoses or 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 to prevent engine coolant from spurting out when removing the tester. 
  • Be careful also not to deform the filler neck of coolant filler tank when installing or removing tester.
