      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 consists of a combination of low phosphates and organic acids).

      • Please contact any authorized TOYOTA dealer or repairer or another duly qualified and equipped professional for further details.

      • The thermostat open timing can be confirmed by pressing the inlet radiator hose by hand, and checking when the coolant starts to flow inside the hose.

    4. Further add coolant into the radiator reservoir until it reaches the FULL line.

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

      If the coolant level is low, add coolant.

    6. Using a 6 mm hexagon wrench, install the vent plug.

      Torque:
      1.5 N*m  { 15 kgf*cm, 13 in.*lbf }

    7. Bleed air from the cooling system.

      Note

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


      1. While idling the engine for approximately 10 minutes, make sure the coolant remains at the FULL line by adding coolant as necessary.

      2. A01GJEM

        After idling the engine for 10 minutes, add coolant until it reaches the B line.

        Capacity
        Approximately 2.5 to 3.5 liters (2.6 to 3.7 US qts, 2.2 to 3.1 Imp. qts)
        Text in Illustration
        A01GKOV B Line

        Tech Tips

        The B line is the lower edge of the inner wall of the filler neck.

      3. Close the radiator reservoir cap, and run the engine at 1500 to 2000 rpm for 5 minutes.

        CAUTION:


        • 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 SLLC starts to flow inside the hose.

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

    9. Check the coolant level.

      If the coolant level is below the FULL line, add coolant until it reaches the FULL line.

  5. INSPECT FOR ENGINE COOLANT LEAK

    CAUTION:

    Do not remove the radiator reservoir cap while the engine and radiator are still hot. Pressurized, hot engine coolant and steam may be released and cause serious burns.

    Note

    Before 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 the radiator cap tester, increase the pressure inside the radiator to 118 kPa (1.2 kgf/cm2, 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 head.

  6. PERFORM INITIALIZATION

    Note

    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.


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

    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 intelligent tester 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.

      Standard
      Condition Engine Idle Speed
      A/C switched off 700 to 800 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 / 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.
