    1. A01CGE1

      Measure the valve opening pressure.


      1. If there are water stains or foreign matter on O-ring 1, clean it with water and finger scouring.

      2. Check that O-ring 1 is not deformed, cracked or swollen.

      3. Apply engine coolant to O-ring 1 and rubber packing 2 before using a radiator cap tester.

      4. A01CBSCE01

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

      5. Pump the 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.

        Judgment Criterion
        Item Specified Condition

        Standard value

        (for brand-new cap)

        94 to 122 kPa (1.0 to 1.2 kgf/cm2, 13.5 to 17.8 psi)

        Minimum standard value

        (for used cap)

        79 kPa (0.8 kgf/cm2, 11.4 psi)

        If the result is not as specified, replace the radiator reservoir cap sub-assembly.
