      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).

      • Contact your TOYOTA dealer for further details.

    2. Check the coolant level inside the radiator by squeezing the inlet and outlet radiator hoses several times by hand. If the coolant level goes down, add coolant.

    3. Install the radiator cap.

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

    5. Bleed air from the cooling system.


      1. Warm up the engine until the thermostat opens.

        While the thermostat is open, circulate the coolant for several minutes.

      2. Press the inlet and outlet radiator hoses several times by hand to bleed air.

        Note


        • Be careful as the radiator hoses are hot.

        • Keep your hands away from the radiator fan.

    6. Stop the engine and wait until the coolant cools down.

    7. Remove the radiator cap and check the coolant level.

    8. If the coolant level has dropped, add coolant.

    9. Check the coolant level inside the radiator reservoir tank again. If it is below the full level, add coolant.

  21. INSPECT FOR FUEL LEAK


    1. Perform the Active Test.


      1. Connect the intelligent tester to the DLC3.

      2. Start the engine.

      3. Turn the intelligent tester on.

      4. Select the following menu items: Powertrain / Engine / Active Test.

      5. Perform the Active Test.

        Intelligent Tester Display Test Details Control Range Diagnostic Notes
        Test the Fuel Leak Fuel leaks (common rail internal fuel pressure is raised) Stop/Start

        • Fuel pressure inside common rail pressurized to specified value and engine speed increased to 2000 rpm when Start is selected.

        • Above conditions preserved while Start is selected.

  22. INSPECT FOR COOLANT LEAK


    1. Remove the radiator cap.

      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.

    2. A01CIGLE01

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

    3. Warm up the engine.

    4. Using a radiator cap tester, increase the pressure inside the radiator to 137 kPa (1.4 kgf/cm2, 19.9 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.

    5. Install the radiator cap.
