      Torque:
      2.5 N*m  { 25 kgf*cm, 22 in.*lbf }
    2. Attach the 4 clamps.

    3. Connect the mass air flow meter connector and attach the clamp.

    4. Connect the No. 2 PCV hose and No. 1 air hose.

  3. ADD ENGINE COOLANT


    1. Add engine coolant.

      Standard capacity
      16.5 liters (17.4 US qts, 14.5 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 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 consists of a combination of low phosphates and organic acids).

      • Press the No. 1 and No. 2 radiator hoses several times by hand, and then check the coolant level. If the coolant level is low, add coolant.

    2. Slowly pour coolant into the radiator reservoir until it reaches the F line.

    3. Install the reservoir cap.

    4. Install the radiator cap.*1

    5. Start the engine and stop it immediately.*2

    6. Allow approximately 10 seconds to pass. Then remove the radiator cap and check the coolant level. If the coolant level has decreased, add coolant.*3

    7. Repeat steps *1, *2 and *3 until the coolant level does not decrease.

      Tech Tips

      Be sure to perform this step while the engine is cold, as air in the No. 1 radiator hose will flow into the radiator if the engine is warmed up and the thermostat opens.

    8. Install the radiator cap.*4

    9. Set the air conditioning as follows.*5

      Item Condition
      Fan speed Any setting except off
      Temperature Toward WARM
      Air conditioning switch Off
    10. Start the engine, warm it up until the thermostat opens, and then continue to run the engine for several minutes to circulate the coolant.*6

      CAUTION:


      • Wear protective gloves. Hot areas on the parts may injure your hands.

      • Be careful of the fan.

      • Be careful as the engine, radiator and radiator hoses are hot and can cause burns.

      Note


      • Immediately after starting the engine, if the radiator reservoir does not have any coolant, perform the following: 1) stop the engine, 2) wait until the coolant has cooled down, and 3) add coolant until the coolant is filled to the F line.

      • Do not start the engine when there is no coolant in the radiator reservoir.

      • Pay attention to the needle of the engine coolant temperature receiver gauge. Make sure that the needle does not show an abnormally high temperature.

      • If there is not enough coolant, the engine may burn out or overheat.

      Tech Tips


      • Press the No. 1 and No. 2 radiator hoses several times by hand to bleed air while warming up the engine.

      • The thermostat opening timing can be confirmed by pressing the No. 2 radiator hose by hand and checking when the engine coolant starts to flow inside the hose.

    11. Stop the engine, wait until the engine coolant cools down to ambient temperature. Then remove the radiator cap and check the coolant level.*7

      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.

    12. If the coolant level has decreased, add coolant and warm up the engine until the thermostat opens.*8

    13. If the coolant level has not decreased, check that the coolant level in the radiator reservoir is at the F line.

      If the coolant level is below the F line, repeat steps *4 through *8.

      If the coolant level is above the F line, drain coolant until the coolant level reaches the F line.

  4. INSPECT FOR COOLANT LEAK

    CAUTION:

    To avoid being burned, do not remove the radiator reservoir cap while the engine and radiator are still hot. Thermal expansion may cause hot engine coolant and steam to blow out from the radiator.


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

    2. Warm up the engine.

    3. Using the radiator cap tester, increase the pressure inside the radiator to 123 kPa (1.3 kgf/cm2, 18 psi), and then check that the pressure does not drop.

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

  5. INSTALL NO. 1 ENGINE UNDER COVER SUB-ASSEMBLY


    1. Install the No. 1 engine under cover sub-assembly with the 10 bolts.

      Torque:
      29 N*m  { 296 kgf*cm, 21 ft.*lbf }
  6. INSTALL FRONT FENDER SPLASH SHIELD SUB-ASSEMBLY LH


    1. Push in the clip to install the front fender splash shield sub-assembly LH.

    2. Install the 3 bolts and 2 screws.

  7. INSTALL FRONT FENDER SPLASH SHIELD SUB-ASSEMBLY RH

    Tech Tips

    Use the same procedure described for the LH side.

  8. INSTALL V-BANK COVER SUB-ASSEMBLY

  9. INSTALL UPPER RADIATOR SUPPORT SEAL


    1. Install the upper radiator support seal with the 3 clips.

  10. INSTALL ENGINE ROOM SIDE COVER RH


    1. Install the engine room side cover RH with the 7 clips.

  11. INSTALL ENGINE ROOM SIDE COVER LH


    1. Install the engine room side cover LH with the 7 clips.

  12. PERFORM INITIALIZATION

    Note


    • Be sure to perform this procedure after reassembling the throttle body with motor assembly or removing and reinstalling any throttle body component.

    • Perform the following procedure after replacing the ECM, throttle body with motor assembly or any throttle body components. The following procedure should also be performed if the throttle body is cleaned.

    • Be sure to perform this procedure after reconnecting the battery cable and replacing the ECM.


    1. Disconnect the EFI fuse, wait at least 60 seconds, and then reconnect the fuse.

    2. Turn the engine switch on (IG) without operating the accelerator pedal.

      Note

      If the accelerator pedal is operated, perform the above steps again.

    3. Connect the GTS to the DLC3 and clear the DTCs Click here.

    4. Start the engine and check that the MIL is not illuminated and that the idle speed is within the specified range when the A/C is switched off after the engine is warmed up.

      Standard
      Condition Engine Idle Speed
      A/C switched off 650 to 750 rpm

      Note


      • Be sure to perform this step with all accessories off.

      • Make sure that the shift lever is in N or P.

    5. Enter the following menus: Powertrain / Engine and ETC / Data List / Throttle Sensor Volt %. Fully depress the accelerator pedal and check that the value is 60% or more.

    6. Perform a road test and confirm that there are no abnormalities.
