      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 your TOYOTA dealer for further details.

      Note

      Never use water as a substitute for engine coolant.

    2. Fill the radiator reservoir with TOYOTA Super Long Life Coolant (SLLC) to the F line.

    3. Install the radiator cap.

    4. 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. Maintain the engine speed at 2,500 to 3,000 rpm.

      3. Press the inlet and outlet 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.

    5. Stop the engine and wait until the 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.

    6. A01J31CE01

      Check the coolant level in the radiator reservoir.

      If the coolant level is below the L line, add SLLC to the reservoir F line.

  61. CHECK FOR ENGINE COOLANT LEAKS

    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.


    1. A01J3PJ

      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, 17.1 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 cylinder block and head.

        (Transmission in neutral position)

      5. Remove SST from the DLC3.

      6. Check the ignition timing.

        Standard ignition timing
        7 to 24° BTDC @ idle
        (Transmission in neutral position)

      7. Disconnect the timing light from the engine.

      8. Install the air cleaner cap.

  66. INSPECT ENGINE IDLE SPEED


    1. A01J3Z7E01

      When using intelligent tester:

      Check the idle speed.


      1. Connect the intelligent tester to the DLC3.

        Tech Tips

        Refer to the intelligent tester operator's manual for further details.

      2. Switch the air conditioning OFF.

      3. Race the engine at 2,500 rpm for approximately 90 seconds.

      4. Check the idle speed.

        Standard idle speed
        700 +-50 rpm
