RADIATOR ON-VEHICLE INSPECTION

PROCEDURE


  1. CHECK RADIATOR CAP SUB-ASSEMBLY


    1. A002BC3C03
      *a Rubber Packing (1)
      *b Rubber Packing (2)
      *c Rubber Packing (3)
      *d Valve Seat

      Measure the valve opening pressure.


      1. If there are water stains or foreign matter on the rubber packings (1), (2) or (3), clean the part(s) with water and finger scouring.

      2. Check that the rubber packings (1), (2) and (3) are not deformed, cracked or swollen.

      3. Check that the rubber packing (3) and valve seat are not stuck together.

      4. Apply engine coolant to the rubber packings (2) and (3) before using a radiator cap tester.

      5. A002A2BC11
        *1 Radiator Cap Sub-assembly
        *a Radiator Cap Tester
        *b 30° or more

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

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

        Pumping Speed
        1 pump per second

        Tech Tips

        Even if the radiator cap sub-assembly cannot maintain the maximum pressure, it is not a defect.

        Result
        Item Specified Condition

        Standard value

        (for brand-new radiator cap sub-assembly)

        94 to 122 kPa (1.0 to 1.2 kgf/cm2, 13.6 to 18 psi)

        Minimum standard value

        (for used radiator cap sub-assembly)

        94 kPa (1.0 kgf/cm2, 13.6 psi)

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

      1. Check that the washer nozzle is not clogged.

      2. A002BKQ

        Insert the washer nozzle into the space in front of the cooler condenser assembly and spray it.

        Note


        • Clean the fins of the cooler condenser assembly by spraying the entire area for 150 seconds. Repeat this process twice.

        • Set the air pressure to 0.4 MPa (4.1 kgf/cm2, 58 psi).

        • Check that water sprays in mist form from the nozzle.

        • Keep the nozzle parallel to the cooler condenser assembly.

        • Do not allow the nozzle to contact the fins of the cooler condenser assembly.

        • Keep the nozzle moving while spraying water.

        • Do not spray the cooler compressor assembly or generator assembly excessively.
