РАДИАТОР (кроме моделей с кузовом типа "седан") ПРОВЕРКА БЕЗ СНЯТИЯ С АВТОМОБИЛЯ

PROCEDURE


  1. INSPECT RESERVE TANK CAP


    1. A00YA9CC03
      *a O-ring
      *b Rubber Packing

      Measure the valve opening pressure.


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

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

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

      4. A00YBATC05
        *1 Reserve Tank Cap
        *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

        Tech Tips

        *: Even if the reserve tank 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, 13.6 to 18 psi)

        Minimum standard value

        (for used cap)

        78 kPa (0.8 kgf/cm2, 11.3 psi)

        If the maximum pressure is less than the minimum standard value, replace the reserve tank cap.
