      Table 1. Text in Illustration
      *1 Air Drain Plug

    6. Add engine coolant to the radiator inlet opening until engine coolant overflows from the engine air drain cock hole. Then tighten the air drain cock plug.

      13 N*m 130 kgf*cm 9 ft.*lbf

    7. Continue to add engine coolant to the radiator inlet opening until engine coolant overflows from the radiator air drain hole. Then tighten the air drain plug.

      1.5 N*m 15 kgf*cm 13 in.*lbf
      Tip:

      If the engine coolant level at the radiator inlet opening drops after squeezing the No. 1 radiator hose and No. 2 radiator hose, add engine coolant.

    8. Slowly fill the radiator assembly with engine coolant.

      Standard Capacity
      Condition Specified Condition
      w/ Rear Heater 11.7 liters (12.4 US qts, 10.3 Imp. qts)
      w/o Rear Heater 9.5 liters (10.1 US qts, 8.4 Imp. qts)
      Note:

      Never use water as a substitute for engine coolant.

      Tip:

      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).

    9. Slowly pour engine coolant into the radiator reservoir tank until it reaches the full line.

    10. 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.

    11. Bleed air from the cooling system.


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

        Tip:

        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.

      2. Maintain the engine speed at 2500 to 3000 rpm.

      3. 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 reservoir tank still has some engine coolant in it.

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

        • If the radiator reservoir tank 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 reservoir tank 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 reservoir tank.

    INSPECT FOR COOLANT LEAK

    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. A017G83

      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 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 heater core, cylinder block and cylinder head.
