  3. ADD ENGINE COOLANT


    1. Tighten the radiator drain cock plug by hand.

    2. Add engine coolant.

      Standard capacity
      8.6 liters (9.1 US qts, 7.6 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 is a combination of low phosphates and organic acids).

      • 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.

      *a B Line

      Continue adding engine coolant until it reaches the B line. (*1)

    4. Install the reserve tank cap. (*2)

    5. Run the engine at about 2000 rpm to warm it up until the thermostat opens. While the thermostat is open, circulate the engine coolant for several minutes. (*3)

      CAUTION:


      • 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 radiator reserve tank runs out of engine coolant just after the engine is started, stop the engine immediately, wait until the engine coolant has cooled down, and then add engine coolant.

      • Make sure that the radiator reserve tank 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.

    6. Stop the engine and wait until the engine coolant cools down. (*4)

      *a Full Line
      *b Low Line

      Check that the engine coolant level is between the full line and low line. (*5)

      Tech Tips


      • If the engine coolant level is below the low line, remove the reserve tank cap and repeat steps from (*1) to (*5).

      • If the engine coolant level is above the full line, drain engine coolant so that the engine coolant level is between the full line and low line.

  4. INSPECT FOR COOLANT LEAK


    1. Remove the reserve tank cap.

      CAUTION:

      Do not remove the reserve tank cap while the engine and radiator are still hot. Pressurized, hot engine coolant and steam may be released and cause serious burns.

      *1 Radiator Cap Tester

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

    3. Warm up the engine.

    4. Pump the radiator cap tester to 118 kPa (1.2 kgf/cm2, 17 psi), and then check that the pressure does not drop.

      If the pressure drops, check the hoses, radiator and water pump for leaks.

      If there are no signs of external coolant leaks, check the heater core, cylinder block and head.

    5. Reinstall the reserve tank cap.

  5. INSTALL OUTER COWL TOP PANEL SUB-ASSEMBLY


    1. A01CCFB

      Install the outer cowl top panel with the 8 bolts.

      Torque:
      8.8 N*m  { 90 kgf*cm, 78 in.*lbf }

    2. Connect the 2 clamps to the outer cowl top panel.

    3. Remove the protective tape.

  6. INSTALL BRAKE MASTER CYLINDER RESERVOIR WITH BRACKET


    1. A01CBAK

      Install the brake master cylinder reservoir with bracket to the outer cowl top panel with the 2 nuts.

      Torque:
      6.5 N*m  { 66 kgf*cm, 58 in.*lbf }

  7. INSTALL WINDSHIELD WIPER MOTOR AND LINK


    1. See the steps from "Install windshield wiper motor and link assembly" through "Install windshield wiper arm cover" Click here.

  8. INSTALL NO. 1 ENGINE UNDER COVER

  9. PERFORM INITIALIZATION

    Note

    Be sure to perform this procedure after reassembling the throttle body assembly, removing and reinstalling any throttle body component or replacing the ECM.


    1. Disconnect the cable from the negative (-) battery terminal. Wait at least 60 seconds and reconnect the cable.

      Note

      When disconnecting the cable, some systems need to be initialized after the cable is reconnected Click here.

    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 intelligent tester 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 air conditioning is switched off after the engine is warmed up.

      Standard
      Condition Engine Idle Speed
      A/C switched off 670 to 770 rpm

      Note


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

      • Make sure that the shift lever is in N.

    5. Enter the following menus: Powertrain/ Engine and ECT/ Data List/ Throttle Sensor Position. 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.
