Radiator: Testing and Inspection

INSPECTION





1. Remove the radiator cap, top off the radiator with coolant, and then attach the tester in place of cap.
2. Apply a pressure of 157 kPa (1.6 kg/cm2, 23 psi) to the radiator to check if:
^ Engine coolant leaks at/around radiator.
^ Engine coolant leaks at/around hoses or connections.

CAUTION:
^ 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 radiator when installing or removing the tester.
