      *1 Air Bleed Valve 1
      *2 Air Bleed Valve 2

      Loosen the air bleed valve 1 and the air bleed valve 2.

    3. Add TOYOTA Super Long Life Coolant (SLLC).

      Standard Capacity
      Item Capacity
      w/o Combustion Type Power Heater 4.5 liters (4.8 US qts, 4.0 Imp. qts)

      Note

      Never use water as a substitute for engine coolant.

      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).

      *1 B Line

      Add coolant to the B line of the radiator reserve tank.

    5. Squeeze the inlet and outlet radiator hoses several times by hand, and then check the level of the coolant.

      If the coolant level is low, add coolant.

      *1 Air Bleed Valve 1
      *2 Air Bleed Valve 2

      Tighten the air bleed valve 1 and the air bleed valve 2.

    7. Install the reserve tank cap sub-assembly.

    8. Start the engine and warm it up.

    9. Bleed air from the cooling system.

      Note


      • Before starting the engine, turn the A/C switch off.

      • Adjust the air conditioning temperature setting to MAX (HOT).

      • Adjust the air conditioning blower setting to LO.


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

        Tech Tips

        Thermostat opening timing can be determined by squeezing the inlet radiator hose, and sensing vibrations when the engine coolant starts to flow inside the hose.

        CAUTION:

        When squeezing the radiator hoses:
        • Wear protective gloves.

        • Be careful as the radiator hoses are hot.

        • Keep your hands away from the radiator fan.

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

      *1 FULL Line
      *2 LOW Line

      After the engine has cooled down, check that the coolant level is between the FULL and LOW lines.

      If the coolant level is low, add coolant to the reservoir tank FULL line.

  5. ADD ENGINE COOLANT (w/ Combustion Type Power Heater)


    1. Tighten the radiator drain cock plug.

    2. A011BIVE01

      *1 Air Bleed Valve 1
      *2 Air Bleed Valve 2

      Loosen the air bleed valve 1 and the air bleed valve 2.

    3. Add TOYOTA Super Long Life Coolant (SLLC).

      Standard Capacity
      Item Capacity
      w/ Combustion Type Power Heater 4.9 liters (5.2 US qts, 4.3 Imp. qts)

      Note

      Never use water as a substitute for engine coolant.

      *2 Air Bleed Valve 2

      Tighten the air bleed valve 1 and the air bleed valve 2.

    7. Start the engine, maintain the speed at 3000 rpm for 10 seconds, and idle the engine for 10 seconds. Repeat the same procedure above 4 more times.

    8. Install the reserve tank cap sub-assembly.

    9. Loosen the air bleed valve 1 and the air bleed valve 2.

    10. Add 350 cc (21.3 cu in.) coolant.

    11. Tighten the air bleed valve 1 and the air bleed valve 2.

    12. Start the engine and warm it up.

    13. Bleed air from the cooling system.

      *1 FULL Line
      *2 LOW Line

      After the engine has cooled down, check that the coolant level is between the FULL and LOW lines.

      If the coolant level is low, add coolant to the reservoir tank FULL line.

  6. INSPECT FOR ENGINE COOLANT LEAK

    CAUTION:

    To avoid the danger of being burned, do not remove the radiator cap sub-assembly while the engine and radiator assembly are still hot. Thermal expansion will cause hot engine coolant and steam to blow out from the radiator assembly.

      *1 Radiator Cap Tester

      Fill the radiator assembly with engine coolant, and attach a radiator cap tester.

    2. Pump the tester to 118 kPa (1.2 kgf/cm2, 17.1 psi), and then check that the pressure does not drop.

      If the pressure drops, check the hoses, radiator assembly and water pump assembly for leaks. If there are no signs or traces of external engine coolant leaks, check the heater core, cylinder block and head.
