Scheme 26

1. Remove the radiator cap, fill the radiator with engine coolant, and then install the tester to the installation position of cap.
2. Apply a pressure of 157 kPa (1.6 kg/cm 2 , 23 psi) to the radiator and check the following points

1. Leakage from the radiator or its vicinity
2. Leakage from the hose or its connections

Scheme 27

1. Attach the radiator cap to tester.
2. Increase pressure until the tester gauge pointer stops. Radiator cap is functioning properly if it holds the service limit pressure for five to six seconds. Replace the cap if it is opened under a pressure less than the service limit value.

Standard

93 - 123 kPa (0.95 - 1.25 kg/cm 2 , 14 - 18 psi)

Service limit

83 kPa (0.85 kg/cm 2 , 12 psi)
