Radiator Cap: Component Tests and General Diagnostics
1. Use an adapter to attach the cap to the tester.
2. Increase the pressure until the gauge stops moving.
Main valve opening pressure: 81.4 - 108 kPa (0.83 - 1.1 kg/cm2, 11.8 - 15.6 psi)
Limit: 65 kPa (0.65 kg/cm2, 9.2 psi)
3. Check that the pressure level is maintained at or below the limit.
4. Replace the radiator cap if the reading does not remain at or below the limit.
NOTE: Be sure that the cap is clean before testing, since rust or other foreign material on the cap seal will cause an incorrect indication.
