INSTALL INTAKE MANIFOLD

1. Install a new gasket onto the intake manifold.

2. 

   Text in Illustration

   *1	Intake Manifold Insulator
   *a	Line

   Install the intake manifold insulator to the intake manifold.

   Tech Tips

   Insert the protrusions of the intake manifold insulator into the grille of the intake manifold.

   Note

   

   Insert the intake manifold insulator until the position of the line as shown in the illustration.

3. Install the intake manifold with the 5 bolts and 2 nuts.

   Torque:

   25 N*m  { 255 kgf*cm, 18 ft.*lbf }

4. Install the bolt and wire harness bracket to the intake manifold.

   Torque:

   8.5 N*m  { 87 kgf*cm, 75 in.*lbf }

5. Connect the vacuum hose to the intake manifold, and slide the clamp to secure the hose.

6. Connect the No. 3 PCV hose to the intake manifold, and slide the clamp to secure the hose.

7. Attach the 2 wire harness clamps to the wire harness bracket.

8. Connect the purge line hose to the vacuum switching valve, and slide the clamp to secure the hose.

9. Connect the vacuum switching valve connector.

ADD ENGINE COOLANT

1. Tighten the radiator drain cock plug by hand.

2. Tighten the cylinder block water drain cock plug.

   Torque:

   13 N*m  { 130 kgf*cm, 9 ft.*lbf }

3. Fill the radiator reservoir assembly with engine coolant to the top of the inlet.

   Standard Capacity
   11.2 liters (11.8 US qts, 9.9 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. Remove the 2-way that is located near the throttle body assembly.

5. When air is bleed and the engine coolant drains out, install the 2-way.

6. Add coolant through the radiator reservoir assembly filler opening until the coolant reaches the B line and install the radiator reservoir cap sub-assembly. [*1]

7. Warm up the engine until the thermostat opens. While the thermostat is open, circulate the coolant for several minutes. [*2]

   CAUTION:

   
   

   • Wear protective gloves.

   • Be careful as the radiator hoses are hot.

   • Keep your hands away from the radiator fans.

   Note

   
   

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

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

   • Make sure that the needle does not show an abnormally high temperature.

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

   Tech Tips

   
   

   • Press the No. 2 and No. 3 radiator hoses several times by hand, and then check the level of the engine coolant.

   • The thermostat open timing can be confirmed by pressing the No. 3 radiator hose by hand, and checking when the engine coolant starts to flow inside the hose.

8. Stop the engine, and wait until the engine coolant cools down to ambient temperature. [*3]

9. Check the engine coolant level in the radiator reservoir assembly. [*4]

   Tech Tips

   
   

   • If the engine coolant level is below the LOW line, repeat steps *1 through *4.

   • If the engine coolant level is above the FULL line, drain engine coolant until the engine coolant level is between the FULL and LOW line.

INSPECT FOR FUEL LEAK

1. Make sure that there are no fuel leaks after performing maintenance on the fuel system.

   
   

   1. Connect the GTS to the DLC3.

   2. Turn the ignition switch to ON and turn the GTS on.

      Note

      Do not start the engine.

   3. Enter the following menus: Powertrain / Engine and ECT / Active Test / Control the Fuel Pump / Speed.

   4. Check that there are no fuel leaks from the fuel system.

      If there are fuel leaks, repair or replace parts as necessary.

   5. Turn the ignition switch off.

   6. Disconnect the GTS from the DLC3.

INSPECT FOR COOLANT LEAK

1. Снимите пробку расширительного бачка радиатора.

2. Заполните расширительный бачок радиатора охлаждающей жидкостью, а затем подсоедините приспособление для опрессовки системы охлаждения и проверки пробки радиатора.

3. Прогрейте двигатель.

4. С помощью приспособления для опрессовки системы охлаждения и проверки пробки радиатора увеличьте давление в радиаторе до 137 кПа (1,4 кгс/см², 20 фунтов на кв. дюйм) и убедитесь, что давление не падает.

   Если давление снижается, проверьте на наличие утечек шланги, радиатор в сборе и насос системы охлаждения двигателя в сборе.

   Если нет следов или признаков утечки внешней охлаждающей жидкости, проверьте сердцевину отопителя, блок цилиндров и головку блока цилиндров.

5. Установите пробку расширительного бачка радиатора.
