COOLANT (w/o EGR Cooler) ON-VEHICLE INSPECTION


  1. REMOVE NO. 1 ENGINE UNDER COVER

  2. DRAIN ENGINE COOLANT

    Note

    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.


    1. A01DY58E01

      Drain the coolant by removing the reservoir cap and, using a wrench, remove the vent plug.

    2. Loosen the cylinder block drain cock plug and the radiator drain cock plug.

      Tech Tips

      Collect the coolant in a container and dispose of it according to the regulations in your area.

  3. ADD ENGINE COOLANT


    1. Tighten the radiator drain cock plug by hand.

    2. Tighten the cylinder block drain cock plug.

      8.0 N*m  { 82 kgf*cm, 71 in.*lbf }
    3. A01DYVNE01

      Fill the radiator with TOYOTA Super Long Life Coolant (SLLC) to the reservoir tank's B line.

      Standard Capacity
      Item Specified Condition
      for Automatic Transmission 11.1 liters (11.7 US qts, 9.8 Imp. qts)
      for Manual Transmission 9.8 liters (10.4 US qts, 8.6 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 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.

    4. Press the radiator hose inlet and radiator hose outlet several times by hand, and then check the level of the coolant.

      If the coolant level drops below the B line, add TOYOTA SLLC to the B line.

    5. Install the radiator reservoir cap.

    6. A01DY58E01

      Using a wrench, install the vent plug.

      Torque:
      2.0 N*m  { 20 kgf*cm, 18 in.*lbf }

    7. 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 2500 to 3000 rpm.

      3. Press the radiator hose inlet and radiator hose outlet 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.

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

        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.

      After the coolant cools down, check that the coolant level is at the F line.

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

  4. INSPECT FOR COOLANT LEAK

    Note

    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.


    1. A01E06UE01

      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.

  5. INSTALL NO. 1 ENGINE UNDER COVER

    Torque:
    28 N*m  { 286 kgf*cm, 21 ft.*lbf }
