COOLANT REPLACEMENT

PROCEDURE


  1. DRAIN ENGINE COOLANT

    CAUTION:

    To avoid being burned, do not remove the reservoir cap while the engine and radiator are still hot.

    Thermal expansion may cause hot engine coolant and steam to blow out from the radiator reservoir assembly.


    1. A01HJBRC05
      *a Vinyl Tube

      Install a vinyl tube to the radiator drain cock plug on the radiator side.

    2. Loosen the radiator drain cock plug.

      A01HH3QC01
      *1 Reservoir Cap *2 Radiator Reservoir Assembly
      *3 Radiator Drain Cock Plug - -

      Tech Tips

      Collect the engine coolant in a container and dispose of it according to the regulations in your area.

    3. Remove the reservoir cap and drain the engine coolant.

    4. Tighten the radiator drain cock plug by hand.

    5. Remove the vinyl tube from the radiator drain cock plug.

  2. ADD ENGINE COOLANT


    1. A01HE1VC02
      B008IUL B Line

      Add engine coolant to the radiator reservoir filler opening until it is filled to the B line at the base of the reservoir filler neck.

      Standard capacity
      6.0 liters (6.3 US qts, 5.3 Imp. qts)

      Note

      Never use water as a substitute for engine coolant.

      Tech Tips


      • The B line is the lower edge of the inner wall of the filler neck.

      • TOYOTA vehicles are filled with TOYOTA SLLC at the factory. In order to avoid damage to the engine cooling system and other technical problems, only use TOYOTA SLLC or similar high quality ethylene glycol based non-silicate, non-amine, non-nitrite, non-borate coolant with long-life hybrid organic acid technology (coolant with long-life hybrid organic acid technology is a combination of low phosphates and organic acids).

    2. Press the radiator hose sub-assembly and No. 2 radiator hoses several times by hand, and then check the level of the engine coolant. If the engine coolant level drops below the B line, add engine coolant to the B line.

    3. Install the reservoir cap.

    4. Start the engine and warm it up until the cooling fan operates.


      1. Set the air conditioning as follows while warming up the engine.

        Specified Condition
        Item Condition
        Temperature Toward WARM
        Air conditioning switch Off

      2. Maintain the engine speed at 2000 to 2500 rpm and warm up the engine until the cooling fan operates.

        Note


        • Make sure that the radiator reservoir assembly still has some engine coolant in it.

        • Pay attention to the needle of the coolant temperature meter. Make sure that the needle does not show an abnormally high temperature.

        • If there is not enough engine coolant, the engine may burn out or overheat.

        • After starting the engine, if the radiator reservoir assembly does not have any engine coolant, perform the following: 1) stop the engine, 2) wait until the coolant has cooled down, and 3) add engine coolant until the engine coolant is filled to the B line.

        • Run the engine at 2000 rpm until the engine coolant level has stabilized.

    5. Press the radiator hose sub-assembly and No. 2 radiator hoses several times by hand to bleed air.

      CAUTION:


      • Wear protective gloves.

      • Be careful as the radiator hoses are hot.

      • Keep your hands away from the cooling fan.

    6. Stop the engine and wait until the coolant cools down to ambient temperature.

    7. Check that the engine coolant level is between the FULL and LOW lines.

      If the engine coolant level is below the LOW line, repeat all of the procedures above.

      If the engine coolant level is above the FULL line, drain engine coolant so that the engine coolant level is between the FULL and LOW lines.

  3. INSPECT FOR COOLANT LEAK
