   *1	Air Cleaner Hose Clamp

   Connect the air cleaner cap sub-assembly to the throttle with motor body assembly and release the lock of the air cleaner hose clamp.

   Note

   
   

   • Align the groove of the air cleaner cap sub-assembly with the tab of the throttle with motor body assembly and install the hose.

   • Make sure that the tab of the air cleaner hose clamp stays within the range shown by *a.

3. Connect the ventilation hose to the cylinder head cover.

4. Install the air cleaner cap sub-assembly and tighten the 2 bolts.

   Torque:

   5.0 N*m  { 51 kgf*cm, 44 in.*lbf }

5. Connect the wire harness clamp.

6. Connect the mass air flow meter connector.

7. Connect the purge line hose to the 2 clamps.

8. Connect the 2 vacuum switching valve vacuum hoses.

9. Connect the vacuum switching valve connector.

INSTALL INLET AIR CLEANER ASSEMBLY

1. Install the inlet air cleaner assembly with the 2 bolts.

   Torque:

   8.0 N*m  { 82 kgf*cm, 71 in.*lbf }

INSTALL COOL AIR INTAKE DUCT SEAL

1. Install the cool air intake duct seal with the 9 clips.

ADD ENGINE COOLANT

1. Tighten the radiator drain cock plug by hand.

2. Tighten the cylinder block drain cock plug.

   Torque:

   13 N*m  { 130 kgf*cm, 9 ft.*lbf }

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

   Standard capacity
   6.6 liters (7.0 US qts, 5.8 Imp. qts)

   Note

   Never use water as a substitute 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).

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

5. 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.

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 2000 to 2500 rpm.

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

      CAUTION:

      When squeezing the No. 1 and No. 2 radiator hoses:

      
      

      • Wear protective gloves.

      • Be careful as the No. 1 and No. 2 radiator hoses are hot.

      • Keep your hands away from the 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.

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.
