  1. INSPECT RADIATOR RESERVOIR CAP SUB-ASSEMBLY

    1. A005T6IE02

      Measure the valve opening pressure.

      Text in Illustration
      *1 O-Ring
      *2 Rubber Packing

      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.

      4. A005V2TE01

        Attach a cap tester to the reserve tank cap.

        Tech Tips

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

      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 does not necessarily indicate a defect.

        Judgment criterion
        Item Specified Condition

        Standard value

        (for brand-new cap)

        93.3 to 122.7 kPa (0.95 to 1.25 kgf/cm2, 13.5 to 17.8 psi)

        Minimum standard value

        (after using cap)

        78.5 kPa (0.8 kgf/cm2, 11.4 psi)

        If the maximum pressure is less than the minimum standard value, replace the radiator cap sub-assembly.

  2. INSPECT FINS FOR BLOCKAGE

    A005VUO

    1. Check that the radiator and condenser are not blocked with leaves, dirt or insects. Clean the hose connections.

      • If the fins are blocked, wash them with water or a steam cleaner.

      Note

      • If the distance between the steam cleaner and core is too close, the fins may be damaged.

      • Keep the following injection distance.

        Standard Injection Distance
        Injection Pressure Specified Condition

        2942 to 4903 kPa

        (30 to 50 kgf/cm2, 427 to 711 psi)

        		 300 mm (11.8 in.)

        4903 to 7845 kPa

        (50 to 80 kgf/cm2, 711 to 1,138 psi)

        		 500 mm (19.7 in.)

      • If the fins are bent, straighten them with a screwdriver or pliers.

      • Never apply water directly onto the electronic components.

    2. Dry the fins with compressed air.
