When using the radiator cap tester, tilt it more than 30 degrees.

Pump the radiator cap tester several times, and check the maximum pressure.
Pumping speed: 1 pump/second
HINT:
Stop pumping when the valve opens and read the gauge. The gauge must be within the standard values listed below when the pressure valve
opens. The cap is considered OK when the pressure holds steady or falls very slowly, but holds within the standard values listed below for one
minute.
Specification:
If the maximum pressure is less than the minimum standard value, replace the radiator cap sub-assembly.
