RADIATOR ON-VEHICLE INSPECTION


  1. CHECK RADIATOR CAP SUB-ASSEMBLY


    1. A01E22Z

      Measure the valve opening pressure.


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

      2. Check that 1, 2 or 3 is not deformed, cracked or swollen.

      3. Check that 3 and 4 are not stuck together.

      4. Apply engine coolant to 2 and 3 before using the radiator cap tester.

      5. When using the cap tester, tilt it more than 30 degrees.

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

        Pumping speed
        1 pump per second

        *: Even if the cap cannot maintain the maximum pressure, it is not 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.
