      1. Install a new gasket to the engine coolant temperature sensor.
      2. Using SST, install the engine coolant temperature sensor to the cylinder head sub-assembly.
        • SST: 09817-33191 

        Torque: 19.6 N.m (200 kgf/cm, 14 ft.lbf) 

        NOTE:

        If the engine coolant temperature sensor has been struck or dropped, replace it.

      3. Connect the engine coolant temperature sensor connector.
  2. INSTALL INTAKE MANIFOLD WITH INTERCOOLER ASSEMBLY 

    HINT: 

    Perform this procedure only when replacement of the engine coolant temperature sensor (for Cylinder Head Side) is necessary.

    Refer to INSTALLATION [10/2022 - ]

  3. INSTALL ENGINE COOLANT TEMPERATURE SENSOR (for Water Inlet Housing Side) 
    1. GTY1105284Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
      *a Torque Wrench Fulcrum Length *b Ball Joint Lock Nut Wrench
      1. Install a new gasket to the engine coolant temperature sensor.
      2. Using a ball joint lock nut wrench, install the engine coolant temperature sensor to the water inlet housing.

        Specified tightening torque 

        Torque: 19.6 N.m (200 kgf/cm, 14 ft.lbf) 

        NOTE:

        If the engine coolant temperature sensor has been struck or dropped, replace it.

        HINT: 

        • Calculate the torque wrench reading when changing the fulcrum length of the torque wrench.

          Refer to PRECAUTION [11/2023 - ]

        • When using a ball joint lock nut wrench (fulcrum length of 150 mm (5.91 in.)) + torque wrench (fulcrum length of 162 mm (6.38 in.)):

          10.2 N.m (104 kgf/cm, 8 ft.lbf)

      3. Connect the engine coolant temperature sensor connector.
  4. CONNECT NO. 1 INTERCOOLER COOLING WATER PIPE 

    HINT: 

    Perform this procedure only when replacement of the engine coolant temperature sensor (for Water Inlet Housing Side) is necessary.

    Torque: 10 N.m (102 kgf/cm, 7 ft.lbf) 

  5. CONNECT NO. 2 INTERCOOLER COOLING WATER PIPE 

    HINT: 

    Perform this procedure only when replacement of the engine coolant temperature sensor (for Water Inlet Housing Side) is necessary.

    Torque: 10 N.m (102 kgf/cm, 7 ft.lbf) 

  6. CONNECT WIRE HARNESS 

    HINT: 

    Perform this procedure only when replacement of the engine coolant temperature sensor (for Water Inlet Housing Side) is necessary.

    Torque: 10 N.m (102 kgf/cm, 7 ft.lbf) 

  7. INSTALL GENERATOR ASSEMBLY 

    HINT: 

    Perform this procedure only when replacement of the engine coolant temperature sensor (for Water Inlet Housing Side) is necessary.

    Refer to INSTALLATION [11/2023 - ]

  8. INSTALL ENGINE COOLANT TEMPERATURE SENSOR (for Outlet Side) 
    1. GTY1108739Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
      1. Apply a light coat of engine coolant to the O-ring of the engine coolant temperature sensor.
      2. Install the engine coolant temperature sensor to the front water by-pass joint with a new clip.
        NOTE:
        • If the engine coolant temperature sensor has been struck or dropped, replace it.
        • If reusing the engine coolant temperature sensor, be sure to inspect the O-ring.
        • Make sure that the O-ring is not cracked or moved out of place when installing the engine coolant temperature sensor.
      3. Connect the engine coolant temperature sensor connector.
  9. ADD ENGINE COOLANT (for Engine) 

    Refer to PROCEDURE - Step 2

  10. INSPECT FOR COOLANT LEAK (for Engine) 

    Refer to PROCEDURE - Step 1

  11. PERFORM INITIALIZATION 
    1. Perform "Inspection After Repair" after replacing the engine coolant temperature sensor.

      Refer to INITIALIZATION [10/2022 - ]

  12. INITIALIZATION AFTER RECONNECTING BATTERY TERMINAL 

    HINT: 

    When disconnecting and reconnecting the battery, there is an automatic learning function that completes learning when the respective system is used.

    Refer to AUTOMATIC LEARNING CHART [11/2023 - ]
