      Note


      • Be careful with the installation direction of the gasket.

      • Do not reuse the gasket.

      • Do not damage the gasket.

      • Do not push in the gasket by using the exhaust pipe when connecting it.

  6. ADD COOLANT (for Engine)


    1. Tighten the radiator drain cock plug.

      *1 B Line

      Add coolant to B line of the reservoir tank.

      Standard Capacity
      Item Capacity
      Engine coolant 7.2 liters (7.6 US qts, 6.3 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 is a combination of low phosphates and organic acids).

      Note

      Never use water as a substitute for engine coolant.

    3. 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.

    4. Put the engine in inspection mode (maintenance mode) Click here.

    5. Install the reservoir tank cap.

    6. Bleed air from the cooling system.

      Note


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

      • Adjust the heater control to the maximum hot setting.

      • Adjust the blower speed to low setting.


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

        Tech Tips

        The thermostat opening timing can be confirmed by squeezing the inlet radiator hose by hand, and sensing vibrations when the engine coolant starts to flow inside the hose.

        CAUTION:

        When squeezing the radiator hose:

        • Wear protective gloves.

        • Be careful as the radiator hoses are hot.

        • Keep your hands away from the radiator fan.

      2. Squeeze the inlet and outlet radiator hoses several times by hand to bleed air from the system.

        CAUTION:

        When squeezing the radiator hose:

        • Wear protective gloves.

        • Be careful as the radiator hoses are hot.

        • Keep your hands away from the radiator fan.

      *1 Full Line
      *2 Low Line

      After the engine has cooled down, check that the coolant level is between full and low.

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

  7. INSPECT FOR COOLANT LEAK (for Engine)

    CAUTION:

    Do not remove the reservoir tank 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 reservoir tank cap.

    2. A0043OJ

      Fill the radiator and reservoir with coolant, and then attach a radiator cap tester.

    3. Put the engine in inspection mode (maintenance mode) Click here.

    4. Warm up the engine.

    5. Using the reservoir cap tester, increase the pressure inside the radiator to 108 kPa (1.1 kgf/cm2, 16 psi), and check that the pressure does not drop. If the pressure drops, check the hoses, radiator, front exhaust pipe assembly and the heater hose around and 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.

    7. Install the reservoir tank cap.

  8. INSPECT FOR EXHAUST GAS LEAK
