      5. Pump the radiator cap tester several times and check the maximum pressure*.

        Pump Speed

        1 pump per second

        *: Even if the cap cannot maintain the maximum pressure, it is not a defect.

        Result

        Item Specified Condition
        Standard pressure
        (for brand-new reserve tank cap (for Intercooler))
        93 to 123 kPa (0.9 to 1.3 kgf/cm2 , 13.5 to 18.0 psi)
        Minimum pressure
        (for used reserve tank cap (for Intercooler))
        79 kPa (0.8 kgf/cm2 , 11.5 psi)

        If the maximum pressure is less than the minimum pressure, replace the reserve tank cap (for Intercooler).
