      *a

      O-ring

      *b

      Rubber Packing

      Measure the valve opening pressure.

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

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

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

        *1

        Reserve Tank Cap (for Intercooler)

        *a

        Radiator Cap Tester

        *b

        30° or more

        When using the radiator cap tester, tilt it upwards 30° or more.

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

        Pump Speed

        1 pump per second

        Tip:

        Even if the reserve tank cap (for Intercooler) 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).
