1. INSTALL THERMOSTAT


    A110388E01

  1. Install a new gasket to the thermostat.

    HINT:
    When installing the thermostat to the gasket, be careful not to deform the gasket. Make sure that the thermostat is properly installed into the groove of the gasket, as shown in the illustration.

  1. Insert the thermostat into the cylinder block with the jiggle valve facing straight upward.

    HINT:
    The jiggle valve may be set within 30°of either side of the prescribed position.



2. INSTALL WATER INLET


    A097637E01

  1. Install the inlet with the 3 bolts.

    Torque:
    13 N*m{ 133 kgf*cm , 10 ft.*lbf }



3. CONNECT RADIATOR HOSE INLET


4. INSTALL AIR CLEANER ASSEMBLY


    A110353

  1. Connect the air cleaner hose.

  1. Install the air cleaner with the 2 bolts.

    Torque:
    14 N*m{ 143 kgf*cm , 10 ft.*lbf }

  1. Tighten the clamp.

  1. Install the clamp and connect the IAT connector.

  1. Connect the ventilation hose.

  1. Slide the clamp to the connection of the hose.



5. CONNECT CABLE TO NEGATIVE BATTERY TERMINAL


6. ADD ENGINE COOLANT

  1. Tighten the radiator drain cock plug by hand.

  1. Tighten the cylinder block drain cock plug.

    Torque:
    8.0 N*m{ 82 kgf*cm , 71 in.*lbf }



    A098989E01

  1. Fill the radiator with TOYOTA Super Long Life Coolant (SLLC) to the reservoir tank's B line.

    Standard capacity:
    9.0 liters (9.5 US qts, 7.9 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.

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

  1. Press the inlet and outlet radiator hoses several times by hand, and then check the level of the coolant.
    If the coolant level drops below the B line, add TOYOTA SLLC to the B line.

  1. Install the radiator reservoir cap.



    A099591E01

  1. Using a wrench, install the vent plug.

    Torque:
    2.0 N*m{ 20 kgf*cm , 18 in.*lbf }

  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 2,000 to 2,500 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.
      1. Be careful as the radiator hoses are hot.
      1. Keep your hands away from the radiator fan.

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

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



    G036768E01

  1. After the coolant cools down, check that the coolant level is at the F line.
    If the coolant level is below the F line, add TOYOTA SLLC to the F line.



7. CHECK FOR ENGINE COOLANT LEAKS

  1. Check for the engine coolant leaks (Click here).



8. INSTALL NO. 1 ENGINE UNDER COVER

  1. Install the cover with the 4 bolts.

    Torque:
    28 N*m{ 286 kgf*cm , 21 ft.*lbf }



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.
