2. Connect the ventilation hose No. 2 with hose clamp.
   

   NOTICE:

   The protrusion of the Head Cover should overlap the paint mark of the hose.

1. Tighten the radiator drain cock plug.
   

2. Loosen the air bleed valve.

3. Remove the water filler cap sub-assembly.
   

4. Slowly fill the radiator with TOYOTA Super Long Life Coolant (SLLC) from the water filler (Coolant level should be within 20 mm (0.787 in.) from the filler tube end).

   Standard Capacity:

   Item	Capacity
   M/T	4.7 liters (5.0 US qts, 4.1 Imp. qts)
   CVT	4.9 liters (5.2 US qts, 4.3 Imp. qts)

   NOTICE:

   Never use water as a substitute for engine coolant.

   HINT:

   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).

5. Remove the reserve tank cap.
   If the coolant level is low, add coolant.
   

6. Fill the radiator reserve tank with coolant to the FULL line.

8. Install the water filler cap sub-assembly and reserve tank cap.
   

9. Start the engine and warm it up.
   

10. Bleed air from the cooling system.
    

    HINT:

    1. Before starting the engine, turn the A/C switch off.
       
    2. Adjust the air conditioning temperature setting to MAX (HOT).
       
    3. Adjust the air conditioning blower setting to LO.
       
    
    

    1. Run the engine intermittently for 7 minutes or more (5 seconds running at 3000 rpm and 45 seconds idling, repeat several times).
       

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

12. After the engine is cooled down, check that the coolant level is between the FULL and LOW lines.

    *b	LOW Line

    If the coolant level is low, add coolant to the reservoir tank FULL line.
    

CAUTION:

To avoid the danger of being burned, do not remove the water filler cap sub-assembly while the engine and radiator assembly are still hot. Thermal expansion will cause hot engine coolant and steam to blow out from the radiator assembly.

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

2. Pump the tester to 118 kPa (1.2 kgf/cm², 17.1 psi), and then check that the pressure does not drop.
   If the pressure drops, check the hoses, radiator assembly and water pump assembly for leaks. If there are no signs or traces of external engine coolant leaks, check the heater core, cylinder block and head.
   

NOTICE:

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

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

2. Turn the ignition switch to ON without operating the accelerator pedal.
   

   NOTICE:

   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 A/C is switched off after the engine is warmed up.
   

   Standard (for CVT):

   Condition	Engine Idle Speed
   A/C switched off	600 to 700 rpm

   Standard (for Manual Transaxle):

   Condition	Engine Idle Speed
   A/C switched off	550 to 650 rpm

   HINT:

   1. Be sure to perform this step with all accessories off.
      
   2. Make sure that the shift lever is in neutral.
      

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