  3. ADD ENGINE COOLANT


    1. Add TOYOTA Super Long Life Coolant (SLLC) to the radiator reservoir filler opening.

    2. A005R4F

      Continue adding TOYOTA SLLC until it is filled to the B line.

      Standard capacity
      5.7 liters (6.0 US qts, 5.0 Imp. qts)

      Note

      Do not substitute plain water for engine coolant.

      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).

    3. 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 drops below the B line, add TOYOTA SLLC to the B line.

    4. Install the radiator cap.

    5. Start the engine and warm it up until the cooling fan operates. While the cooling fan operates, circulate the coolant for several minutes.


      1. Set the air conditioning as follows while warming up the engine.

        Item Specified Condition
        Automatic Air Conditioning System

        Temperature: Toward MAX (HOT)

        Air conditioning switch: off

      2. Maintain an engine speed of 2000 to 2500 rpm and warm up the engine until the cooling fan operates.

        Note


        • Make sure that the radiator reservoir still has some coolant in it.

        • Pay attention to the needle of the water temperature meter. Make sure that the needle does not show an abnormally high temperature.

        • If there is not enough coolant, the engine may burn out or overheat.

        • Immediately after starting the engine, if the radiator reservoir does not have any coolant, perform the following: 1) stop the engine, 2) wait until the coolant has cooled down, and 3) add coolant until the coolant is filled to the B line.

        • Run the engine at 2000 rpm until the coolant level has stabilized.

    6. 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 fan.

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

    8. A005UTJ

      Check that the coolant level is between the FULL and LOW lines.

      If the coolant level is below the LOW line, repeat all of the procedures above.

      If the coolant level is above the FULL line, drain coolant so that the coolant level is between the FULL and LOW lines.

  4. INSPECT FOR COOLANT LEAK


    1. Remove the radiator cap.

      CAUTION:

      To avoid the danger of being burned, do not remove the radiator cap while the engine and radiator are still hot. Thermal expansion will cause hot engine coolant and steam to blow out from the radiator reservoir.

    2. A005RZ8

      Fill the radiator reservoir with coolant, and then attach a radiator cap tester.

    3. Warm up the engine.

    4. Pump the radiator cap tester to 118 kPa (1.2 kgf/cm2, 17 psi), and then check that the pressure does not drop.

      If the pressure drops, check the hoses, radiator and water pump for leakage.

      If there are no signs of external coolant leaks, check the heater core, cylinder block and head.

    5. Reinstall the radiator cap.

  5. INSTALL NO. 1 ENGINE COVER SUB-ASSEMBLY


    1. A00DS8Z

      Install the cover with the 2 nuts.

      Torque:
      9.0 N*m  { 92 kgf*cm, 80 in.*lbf }

  6. PERFORM INITIALIZATION

    Note


    • Be sure to perform this procedure after reassembling the throttle body assembly or removing and reinstalling any throttle body component.

    • Perform the following procedure after replacing the ECM, throttle body assembly or any throttle body components. The following procedure should also be performed if the throttle body is cleaned.

    • Be sure to perform this procedure after replacing the ECM and reconnecting the battery cable.


    1. Disconnect the EFI MAIN and ECTS fuses at the same time. Wait at least 60 seconds, and then reconnect the fuses.

    2. Turn the engine switch on (IG) position without operating the accelerator pedal.

      Note

      If the accelerator pedal is operated, perform the above steps again.

    3. Connect the intelligent tester to the DLC3 and clear the DTCs Click here.

    4. Start the engine and check that the MIL is not illuminated and that the idle speed is within the specified range when the A/C is switched off after the engine is warmed up.

      Standard
      Condition Engine Idle Speed
      A/C switched off 650 to 750 rpm

      Note


      • Be sure to perform this step with all accessories off.

      • Make sure that the shift lever is in N or P.

    5. Enter the following menus: Powertrain / Engine and ECT / Data List / All Data / Throttle Sensor Position. Fully depress the accelerator pedal and check that the value is 60% or more.

    6. Perform a road test and confirm that there are no abnormalities.
