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

Standard Capacity:

Item	Capacity
Engine coolant	5.7 liters (6.0 US qts, 5.0 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).
   
2. Contact your TOYOTA dealer for further details.
   

NOTICE:

Never use water as a substitute for engine coolant.

Squeeze 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.

Tighten the upper radiator drain cock plug.

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

Install the radiator cap sub-assembly and reservoir tank cap.

Start the engine and warm it up.

Bleed air from the cooling system.

NOTICE:

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

   HINT:

   Thermostat opening timing can be determined by squeezing the inlet radiator hose, and sensing vibrations when the engine coolant starts to flow inside the hose.

   CAUTION:

   When squeezing the radiator hoses:

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

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

Add engine coolant to the FULL line on the radiator reservoir.

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

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

Check fuel pump operation.

1. Connect the Techstream to the DLC3.
   

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

   NOTICE:

   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.
   

Check for fuel leaks.

1. There is no fuel leakage after performing maintenance anywhere on the fuel system. If there is a fuel leak, repair or replace parts as necessary.
   

Turn the ignition switch off.

Disconnect the Techstream from the DLC3.

Install the No. 1 engine cover sub-assembly with the 2 nuts.
