      Standard Capacity
      Item Specified Condition
      w/o Transmission Oil Cooler 9.7 liters (10.3 US qts, 8.5 Imp. qts)
      w/ Transmission Oil Cooler 10.0 liters (10.6 US qts, 8.8 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.

  6. 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.

  7. PERFORM INITIALIZATION


    1. w/ Canister Pump Module:

      Note

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


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

        Note

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

      2. Connect the GTS to the DLC3 and clear the DTCs Click here.

      3. Perform the "Inspection After Repairs" Click here.

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

        Standard
        Condition Engine Idle Speed
        A/C switched off 600 to 700 rpm

        Note


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

        • Make sure that the shift lever is in neutral.

      5. Enter the following menus: Powertrain / Engine and ECT / Data List / All Data / Throttle Sensor Position. Sensor Output. 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.

    2. w/o Canister Pump Module:

      Note


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

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

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


      1. Disconnect the cable from the negative (-) battery terminal. Wait at least 60 seconds and reconnect the cable.

        Note

        After the engine switch is turned off, the display and navigation module display (HDD navigation system) records various types of memory and settings. As a result, after turning the engine switch off, make sure to wait at least 60 seconds before disconnecting the cable from the negative (-) battery terminal.

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

        Note

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

      3. Connect the GTS to the DLC3 and clear the DTCs Click here.

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