      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).

      *a Full Line

      Slowly pour engine coolant into the radiator reserve tank assembly until it reaches the full line.

    9. Squeeze the No. 1 radiator hose and No. 2 radiator hose several times by hand, and then check the level of the engine coolant.

      If the engine coolant level is low, add engine coolant.

    10. Install the radiator cap sub-assembly and reserve tank cap.

    11. Bleed air from the cooling system.


      1. Put the engine in inspection mode Click here.

      2. Warm up the engine until the thermostat opens. While the thermostat is open, circulate the engine coolant for several minutes.

        Tech Tips

        The thermostat open timing can be confirmed by squeezing the No. 2 radiator hose by hand, and sensing vibrations when the engine coolant starts to flow inside the No. 2 radiator hose.

      3. Maintain the engine speed at 2500 rpm.

      4. Squeeze the No. 1 radiator hose and No. 2 radiator hose several times by hand to bleed air.

        CAUTION:

        When squeezing the No. 1 radiator hose and No. 2 radiator hose:


        • Wear protective gloves.

        • Be careful as the No. 1 radiator hose and No. 2 radiator hose are hot.

        • Keep your hands away from the fan and No. 2 fan.

        Note


        • If the coolant temperature gauge indicates an excessive temperature, turn off the engine and let it cool.

        • Make sure that the radiator reserve tank assembly still has some engine coolant in it.

        • If the radiator reserve tank assembly does not have enough engine coolant, the engine may overheat or be seriously damaged.

        • If the radiator reserve tank assembly does not have enough engine coolant, perform the following: 1) stop the engine, 2) wait until the engine coolant has cooled down, and 3) add engine coolant until the radiator reserve tank assembly is filled to the full line.

    12. Stop the engine, and wait until the engine coolant cools down.

    13. Add engine coolant to the full line on the radiator reserve tank assembly.

  4. INSPECT FOR COOLANT LEAK (for Engine)

    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. Remove the radiator cap.

    2. A01NIZA

    4. Warm up the engine.

    5. 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, exhaust center pipe assembly and the heater hose around the water temperature switch and engine water pump for leaks. If no external leaks are found, check the heater core, cylinder block and cylinder head.

    6. Remove the radiator cap tester.
