    1. Apply a light coat of engine oil to a new O-ring.

    2. Install the O-ring to the engine oil level dipstick guide.

    3. Install the engine oil level dipstick guide with the bolt.

      Torque:
      10 N*m  { 102 kgf*cm, 7 ft.*lbf }

    4. Install the engine oil level dipstick.

  4. ADD ENGINE COOLANT


    1. Tighten the radiator drain cock plug by hand.

      *a Code Mark

      Slowly fill the radiator assembly with engine coolant.

      Specified Capacity
      Code Mark "M" 6.9 liters (7.3 US qts, 6.1 Imp. qts)
      Code Mark "G" 7.0 liters (7.4 US qts, 6.2 Imp. qts)
      Code Mark "Z" 7.3 liters (7.7 US qts, 6.4 Imp. qts)

      Note

      Do not substitute plain water for engine coolant.

      Tech Tips

      TOYOTA vehicles are filled with TOYOTA SLLC at the factory. In order to avoid damaging 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).

    3. Remove the reserve tank cap.

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

    5. 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.

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

    7. 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 radiator hose and No. 2 radiator hose several times by hand to bleed air from the cooling system.

        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 reserve tank assembly still has some engine coolant in it.

        • If the radiator reserve tank assembly does not have 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.

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

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

  5. ADD ENGINE OIL


    1. Add clean engine oil and install the oil filler cap sub-assembly.

      Standard Oil Grade

      Dry fill 5.3 liters (5.6 US qts, 4.7 Imp. qts)

  6. INSPECT FOR COOLANT LEAK

    Note

    Before performing each inspection, turn the A/C switch off.


    1. B000HO1

      Fill the radiator with 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/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.

  7. INSPECT FOR OIL LEAK


    1. Start the engine. Make sure that there are no engine oil leaks from the area that was worked on.
