    5. Slowly fill the radiator with TOYOTA Super Long Life Coolant (SLLC).

      Specified capacity
      9.1 liters (9.6 US qts, 8.0 lmp. 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).

    6. Slowly pour coolant into the radiator reserve tank assembly until it reaches the full line.

    7. Squeeze 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.

    8. Install the radiator cap sub-assembly and reserve tank cap.

    9. Bleed air from the cooling system.

      Note


      • Before starting the engine, turn the A/C switch off.

      • Adjust the heater control to the maximum hot setting.

      • Adjust the blower speed to the low setting.


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

        Tech Tips

        The thermostat open timing can be confirmed by squeezing the outlet radiator hose by hand, and sensing vibrations when the engine coolant starts to flow inside the hose.

      2. Maintain the engine speed at 2500 to 3000 rpm.

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

        CAUTION:

        When squeezing the radiator hoses:


        • Wear protective gloves.

        • Be careful as the radiator hoses are hot.

        • Keep your hands away from the radiator fans.

        Note


        • Make sure that the radiator reserve tank assembly still has some coolant in it.

        • If the coolant temperature gauge indicates an excessive temperature, turn off the engine and let it cool.

        • If there is not enough coolant, the engine may overheat or be seriously damaged.

        • If the radiator reserve tank assembly does not have enough coolant, perform the following: 1) stop the engine, 2) wait until the coolant has cooled down, and 3) add coolant until the reserve tank assembly is filled to the full line.

    10. Stop the engine, and wait until the engine coolant cools down.

    11. Add engine coolant to the full line on the radiator reserve tank assembly.

  12. INSPECT FOR COOLANT LEAK

    CAUTION:

    Do not remove the radiator cap sub-assembly 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. A01HYQS

      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 118 kPa (1.2 kgf*cm, 17 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.

  13. INSPECT FOR FUEL LEAK


    1. Check fuel pump operation.


      1. Connect the Techstream to the DLC3.

      2. Turn the engine switch on (IG) and turn the Techstream on.

        Note

        Do not start the engine.

      3. Enter the following menus: Powertrain / Engine / Active Test / Control the Fuel Pump / Speed.

      4. Check for pressure in the fuel inlet tube from the fuel line. Check that sounds of fuel flowing from the fuel tank can be heard. If no sounds can be heard, check the integration relay, fuel pump, fuel pump control ECU, ECM and wiring connectors.

    2. Inspect for fuel leaks.


      1. Check that there are no fuel leaks from the fuel system after doing any maintenance or repairs. If there is a fuel leak, repair or replace parts as necessary.

    3. Turn the engine switch off.

    4. Disconnect the Techstream from the DLC3.

  14. INSTALL V-BANK COVER SUB-ASSEMBLY


    1. Fit the 3 retainers and install the V-bank cover sub-assembly.
