THERMOSTAT INSTALLATION


  1. INSTALL WATER INLET WITH THERMOSTAT SUB-ASSEMBLY


    1. Install a new gasket and the water inlet with thermostat sub-assembly with the 3 nuts.

      Torque:
      10 N*m  { 102 kgf*cm, 7 ft.*lbf }

  2. CONNECT NO. 6 WATER BY-PASS HOSE


    1. Connect the No. 6 water by-pass hose to the water inlet and secure it with the clip.

  3. CONNECT NO. 2 RADIATOR HOSE


    1. Connect the No. 2 radiator hose to the water inlet with thermostat sub-assembly and secure it with the clip.

  4. ADD ENGINE COOLANT


    1. Tighten the radiator drain cock plug by hand.

    2. Tighten the 2 cylinder block drain cock plugs.

      Torque:
      13 N*m  { 130 kgf*cm, 9 ft.*lbf }

    3. Add TOYOTA Super Long Life Coolant (SLLC) to the water outlet sub-assembly opening.

      Standard Capacity
      Item Specified Condition
      for LHD 10.9 liters (11.5 US qts, 9.6 Imp. qts)
      for RHD 11.0 liters (11.6 US qts, 9.7 Imp. qts)

      Tech Tips

      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).

    4. Slowly pour coolant into the radiator reservoir tank until it reaches the full line.

    5. Press the No. 1 and No. 2 radiator hoses several times by hand, and then check the level of the coolant.

      If the coolant level is low, add coolant.

    6. Install the radiator cap.

    7. Bleed air from the cooling system.

      Note

      Before starting the engine to warm up the engine, turn the A/C switch off.


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

        CAUTION:

        When pressing the radiator hoses:


        • Wear protective gloves.


        • Be careful as the radiator hoses are hot.


        • Keep your hands away from the radiator fans.

        Tech Tips

        The thermostat open timing can be confirmed by pressing the No. 1 radiator hose by hand, and checking when the engine coolant starts to flow inside the hose.

      2. Maintain the engine speed at 2000 to 2500 rpm.

      3. Press the No. 1 and No. 2 radiator hoses several times by hand to bleed air.

        CAUTION:

        When pressing the radiator hoses:


        • Wear protective gloves.


        • Be careful as the radiator hoses are hot.


        • Keep your hands away from the radiator fans.

    8. 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.

    9. Check the coolant level in the radiator reservoir tank.

      If the coolant level is low, add SLLC to the radiator reservoir tank full line.

  5. INSPECT FOR COOLANT LEAK

    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.

    Note

    Before performing each inspection, turn the A/C switch off.


    1. Fill the radiator with coolant and attach a radiator cap tester.

    2. Warm up the engine.

    3. Using a radiator cap tester, increase the pressure inside the radiator to 137 kPa (1.4 kgf/cm2, 20 psi), and check that the pressure does not drop.

      If the pressure drops, check the hoses, radiator and water pump for leaks. If no external leaks are found, check the heater core, cylinder block and cylinder head.

  6. INSTALL NO. 1 AIR CLEANER INLET


    1. Install the No. 1 air cleaner inlet with the bolt.

      Torque:
      5.0 N*m  { 51 kgf*cm, 44 in.*lbf }

  7. INSTALL COOL AIR INTAKE DUCT SEAL


    1. Install the cool air intake duct seal with the 7 clips.

  8. INSTALL ENGINE ROOM SIDE COVER


    1. Install the engine room side cover with the 4 clips.

  9. INSTALL V-BANK COVER SUB-ASSEMBLY


    1. A01FHZ4E01
      Text in Illustration
      *1 Tip (Round Portion)

      Attach the 3 clips in the order shown in the illustration to install the V-bank cover.

      Note


      • Securely attach the clips.

      • If the clips are forcibly attached or struck with an object, they may be damaged.

      • Do not apply any oil to the tips (round portions).
