    HINT:
    1. 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 consists of a combination of low phosphates and organic acids).
    2. Please contact your TOYOTA dealer for further details.

    NOTICE:
    Never use water as a substitute for engine coolant.

  1. Fill the radiator reservoir with TOYOTA Super Long Life Coolant (SLLC) to the F line.

  1. Bleed air from the cooling system.

    1. Warm up the engine until the thermostat opens.
      While the thermostat is open, circulate the coolant for several minutes.

    2. Maintain the engine speed at 2,500 to 3,000 rpm.

    3. Press the inlet and outlet radiator hoses several times by hand to bleed air.

      CAUTION:
      When pressing the radiator hoses:
      1. Wear protective gloves.
      2. Be careful as the radiator hoses are hot.
      3. Keep your hands away from the radiator fan.

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

    CAUTION:
    Do not remove the radiator cap while the engine and radiator are still hot. Pressurized, hot engine coolant and steam may be released and cause serious burns.


    A112081E01

  1. Check the coolant level in the radiator reservoir.
    If the coolant level is below the L line, add SLLC to the reservoir F line.
