        *a O-ring
        *b Rubber Packing

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

        Note

        Always perform the procedure by hand so as not to damage the O-ring.

      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

        *: 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).
