   Specified capacity
   7.3 liters (7.7 US qts, 6.4 lmp. qts)

   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).

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

4. Squeeze the No. 1 and No. 2 radiator hoses several times by hand, and then check the level of the coolant.

   If the coolant level is low, add coolant.

5. Install the radiator cap sub-assembly and reserve tank cap.

6. 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 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 hose.

   2. Maintain the engine speed at 2500 to 3000 rpm.

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

      CAUTION:

      When squeezing the radiator hoses:

      
      

      • Wear protective gloves.

      • Be careful as the radiator hoses are hot.

      • Keep your hands away from the cooling fans.

      Note

      
      

      • Make sure that the radiator reserve tank assembly still has some 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 coolant, the engine may overheat or be seriously damaged.

      • If the radiator reserve tank assembly does not have enough coolant, perform the following: 1) stop the engine, 2) wait until the coolant has cooled down, and 3) add coolant until the reserve tank assembly is filled to the full line.

7. Stop the engine and wait until the engine coolant cools down.

8. Add engine coolant to the full line on the radiator reserve tank assembly.

CHARGE WITH REFRIGERANT

INSPECT FOR FUEL LEAK

1. Check fuel pump operation.

   
   

   1. Connect the Techstream to the DLC3.

   2. Turn the ignition switch to ON and turn the Techstream 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 for pressure in the fuel inlet tube from the fuel line. Check that sounds of fuel flowing from the fuel tank can be heard. If no sounds can be heard, check the integration relay, fuel pump, ECM and wiring connectors.

2. Inspect for fuel leaks.

   
   

   1. Check that there are no fuel leaks from the fuel system after doing any maintenance or repairs. If there is a fuel leak, repair or replace parts as necessary.

3. Turn the ignition switch off.

4. Disconnect the Techstream from the DLC3.

INSPECT FOR COOLANT LEAK

INSPECT REFRIGERANT LEAK

1. After recharging the air conditioning system with refrigerant, inspect for refrigerant leaks using a halogen leak detector.

2. Carry out the test under the following conditions:

   
   

   • Ignition switch off.

   • Secure good ventilation (the halogen leak detector may react to volatile gases which are not refrigerant, such as gasoline vapor and exhaust gas).

   • Repeat the inspection 2 or 3 times.

   • Measure the pressure to make sure that there is some refrigerant remaining in the air conditioning system.

     Pressure when the compressor is off: approx. 392 to 588 kPa (4.0 to 6.0 kgf/cm², 57 to 85 psi)

3.

   Using a halogen leak detector, inspect for refrigerant leaks from the air conditioning system.

4. 

   Text in Illustration

   *1	Halogen Leak Detector
   *2	Drain Hose

   Bring the halogen leak detector close to the drain hose with the detector power off, and then turn the detector on.

   Tech Tips

   
   

   • After the blower motor has stopped, leave the cooling unit for more than 15 minutes.

   • Bring the halogen leak detector sensor under the drain hose.

   • When bringing the halogen leak detector close to the drain hose, make sure that the halogen leak detector does not react to volatile gases. If it is not possible to avoid interference from volatile gases, the vehicle should be lifted up to allow checking for leaks.

5. If a refrigerant leak is not detected from the drain hose, remove the blower motor control from the cooling unit. Insert the halogen leak detector sensor into the unit and check for a leak.

6. Disconnect the pressure sensor connector and leave it for approximately 20 minutes. Bring the halogen leak detector close to the pressure sensor and check for a leak.

   Tech Tips

   When checking for leaks, the presence of oily dirt at a joint can indicate a leak.

INSPECT IGNITION TIMING

      Note

      
      

      • Confirm the terminals before connecting them. Connecting the wrong terminals may result in damage to electrical components.

      • Turn all electrical systems and the A/C off.

      • Inspect the idle speed with the cooling fans off.

      • When checking the idle speed, the transaxle should be in neutral.

   2. Race the engine at 2500 rpm for approximately 90 seconds.

   3. Check the idle speed.

      Standard idle speed
      610 to 710 rpm
