Radiator: Testing and Inspection

INSPECTION





1. Remove the coolant filler tank cap and fill engine coolant to coolant filler tank, then attach the tester to radiator in place of cap.
2. Apply a pressure of 122 kPa (1.2 kg/cm2, 18 psi) to the radiator to check if:
^ Engine coolant leaks at or around radiator.
^ 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 tester.
^ Be careful not to deform the filler neck of coolant filler tank when installing or removing the tester.
