  3. ADD ENGINE COOLANT


    1. Tighten the radiator drain cock plug by hand.

    2. Close the 2 cylinder block drain cock plugs.

      Torque:
      13 N*m  { 130 kgf*cm, 9 ft.*lbf }

    3. Loosen the air drain cock plug on the water inlet housing.

    4. Add TOYOTA Super Long Life Coolant (SLLC) to the radiator inlet opening until coolant overflows from the air drain cock hole. Then tighten the air drain cock plug.

      *a Code Mark

      Check the code mark on the fan shroud.

    6. Slowly fill the radiator assembly with TOYOTA Super Long Life Coolant (SLLC).

      Specified capacity:
      Code Mark I and V 9.2 liters (9.7 US qts, 8.1 Imp. qts)
      Code Mark W 9.4 liters (9.9 US qts, 8.3 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).

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

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

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

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

    10. 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 the low setting.


      1. 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.

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

      3. Squeeze the No. 1 and No. 2 radiator hoses several times by hand to bleed air.

        CAUTION:

        When squeezing the radiator hoses:


        • Wear protective gloves.

        • Be careful as the radiator hoses are hot.

        • Keep your hands away from the radiator fans.

        Note


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

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

        • If there is not 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.

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

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

  4. ADD ENGINE OIL


    1. A01G8XW

      Add clean engine oil and install the oil filler cap.

      Note

      Do not allow engine oil adhere to the moving parts of the belt tensioner, as this may cause malfunctions.

      If engine oil is on the location indicated by the arrow, replace the belt tensioner.

      Standard Oil Grade:
      Oil Grade Oil Viscosity (SAE)

      • API grade SL "Energy-Conserving", SM "Energy-Conserving", SN "Resource-Conserving" or ILSAC multigrade engine oil

      • 0W-20


      • 5W-20


      • 5W-30


      • 10W-30
      API grade SL, SM or SN multigrade engine oil

      • 15W-40


      • 20W-50
      Standard Capacity
      Item Standard Condition
      Drain and refill with oil filter change 6.1 liters (6.4 US qts, 5.4 Imp. qts)
      Drain and refill without oil filter change 5.7 liters (6.0 US qts, 5.0 Imp. qts)
      Dry fill 6.8 liters (7.2 US qts, 6.0 Imp. qts)

  5. INSPECT FOR COOLANT LEAK

    CAUTION:

    Do not remove the radiator cap sub-assembly 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. A01G6OC

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

    2. Warm up the engine.

    3. Using a radiator cap tester, increase the pressure inside the radiator to 118 kPa (1.2 kgf*cm, 17 psi), and check that the pressure does not drop.

      If the pressure drops, check the hoses, radiator assembly and engine water pump assembly for leaks. If no external leaks are found, check the heater core, cylinder block and cylinder head.

  6. INSPECT FOR OIL LEAK

  7. INSPECT ENGINE OIL LEVEL


    1. Warm up the engine, stop it and wait 5 minutes. The engine oil level should be between the engine oil level dipstick low level mark and full level mark.

      If the engine oil level is low, check for leakage and add engine oil up to the full level mark.

      Note

      Do not add engine oil to above the full level mark.
