Add engine coolant.

Specified capacity:

9.1 liters (9.6 US qts, 8.0 lmp. qts)

HINT:

1. 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 consists of a combination of low phosphates and organic acids).
   

1. Contact your TOYOTA dealer for further details.
   

Slowly pour coolant into the radiator reservoir until it reaches the FULL line.

Press the inlet and outlet radiator hoses several times by hand, and then check the level of the coolant.
If the coolant level is low, add coolant.

Install the radiator cap and reservoir cap.

Bleed air from the cooling system.

NOTICE:

Before starting the engine to warm up the engine, turn the A/C switch OFF.

1. Warm up the engine until the thermostat opens. While the thermostat is open, circulate the coolant for several minutes.
   

   HINT:

   The thermostat open timing can be confirmed by pressing the inlet radiator hose by hand, and checking when the engine coolant starts to flow inside the hose.

   NOTICE:

   When pressing the radiator hoses:

   1. Wear protective gloves.
      
   1. Be careful as the radiator hoses are hot.
      
   1. Keep your hands away from the radiator fans.
      

2. Maintain the engine speed at 2,000 to 2,500 rpm.
   

3. Press the inlet and outlet radiator hoses several times by hand to bleed air.
   

   NOTICE:

   When pressing the radiator hoses:

   1. Wear protective gloves.
      
   1. Be careful as the radiator hoses are hot.
      
   1. Keep your hands away from the radiator fans.
      

Stop the engine, and wait until the engine coolant cools down to ambient temperature.

NOTICE:

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

Check the coolant level in the radiator reservoir.
If the coolant level is low, add SLLC to the radiator reservoir FULL line.

Fill the radiator with coolant and attach a radiator cap tester.

Warm up the engine.

Using a radiator cap tester, increase the pressure inside the radiator to 118 kPa (1.2 kgf*cm², 17 psi), and check that the pressure does not drop.
If the pressure drops, check the hoses, radiator and water pump for leaks. If no external leaks are found, check the heater core, cylinder block and cylinder head.

Connect the intelligent tester to the DLC3.

1. Turn the engine switch on (IG).
   

   NOTICE:

   Do not start the engine.

2. Push the intelligent tester main switch ON.
   

3. Select the following menus: Powertrain / Engine / Active Test / Control the Fuel Pump /Speed.
   

Check the fuel pump operation.

1. Check for pressure in the fuel inlet tube from the fuel line. Check that sound of fuel flowing in the fuel tank can be heard.
   If no sound can be heard, check the integration relay, fuel pump, ECM and wiring connector.
   

Check for fuel leaks.

1. Check that there are no fuel leaks anywhere on the system after performing maintenance.
   If there is a fuel leak, repair or replace parts as necessary.
