8. CONNECT CABLE TO NEGATIVE BATTERY TERMINAL


9. PERFORM INITIALIZATION
  1. Perform initialization (Click here).

    NOTICE:
    Certain systems need to be initialized after disconnecting and reconnecting the cable from the negative (-) battery terminal.


10. ADD ENGINE COOLANT
  1. Tighten the radiator drain cock plug by hand.

  1. Tighten the 2 cylinder block drain cock plugs.

    Torque:
    12.7 N*m{130 kgf*cm, 9 ft.*lbf}
  1. Add engine coolant.

    HINT:
    Add engine coolant until coolant overflows from the vent plug.
    Specified capacity:
    11.0 liters (11.7 US qts, 9.7 lmp. qts)
    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).
    1. Please contact your TOYOTA dealer for further details.
  1. Install the vent plug.

  1. Slowly pour coolant into the radiator reservoir until it reaches the FULL line.

  1. Press the inlet and outlet radiator hoses several times by hand, and then check the level of the coolant.
    If the coolant level is low, add coolant.

  1. Install the radiator cap.

  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.

      HINT:
      Adjust the air conditioner set temperature to MAX (HOT).
    2. Maintain the engine speed at 2,000 to 2,500 rpm.

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

      NOTICE:
      When pressing the radiator hoses:
      1. Wear protective gloves.
      1. Be careful as the radiator hoses are hot.
      1. Keep your hands away from the radiator fan.
  1. Stop the engine, and wait until the engine 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.
