Fill the radiator with TOYOTA Super Long Life Coolant (SLLC) to the B line of the radiator reservoir.

Standard capacity:

9.8 liters (10.4 US qts, 8.6 Imp. qts)

NOTICE:

Never use water as a substitute for engine coolant.

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. Please contact your TOYOTA dealer for further details.
   

Press the inlet and outlet radiator hoses several times by hand, and then check the level of the coolant.
If the coolant level drops below the B line, add TOYOTA SLLC to the B line.

Install the radiator reservoir cap.

Using a wrench, install the vent plug.

Torque:

2.0 N*m{20 kgf*cm, 17 in.*lbf}

Bleed air from the cooling system.

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

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

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

   CAUTION:

   When pressing 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.
      

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

   CAUTION:

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

After the coolant cools down, check that the coolant level is at the F line.
If the coolant level is below the F line, add TOYOTA SLLC to the F line.

Using the hand pump mounted on the fuel filter cap, bleed the air from the fuel system. Continue pumping until the pump resistance increases.

NOTICE:

1. Hand pump pumping speed: Max. 2 strokes/ sec.
   
2. The hand pump must be pushed with a full stroke during pumping.
   
3. When the fuel pressure at the supply pump inlet port reaches a saturated pressure, the hand pump resistance increases.
   
4. If pumping is interrupted during the air bleeding process, fuel in the fuel line may return to the fuel tank. Continue pumping until the hand pump resistance increases.
   
5. If the hand pump resistance does not increase despite consecutively pumping 200 times or more, there may be a fuel leak between the fuel tank and fuel filter, the hand pump may be malfunctioning, or the vehicle may have run out of fuel.
   
6. If air bleeding using the hand pump is incomplete, the common rail pressure does not rise to the pressure range necessary for normal use, and the engine cannot be started.
   

Check if the engine starts.

NOTICE:

1. Even if air bleeding using the hand pump has been completed, the starter may need to be cranked for 10 seconds or more to start the engine.
   
2. Do not crank the engine continuously for more than 20 seconds. The battery may be discharged.
   
3. Use a fully-charged battery.
   

1. When the engine can be started, proceed to the next step.
   

2. If the engine cannot be started, bleed the air again using the hand pump until the hand pump resistance increases (refer to the procedures above). Then start the engine.
   

Turn the ignition switch off.

Connect the intelligent tester to the DLC3.

Turn the ignition switch to ON and turn the intelligent tester on.

Clear the DTCs.

Start the engine.*1

Enter the following menus: Powertrain / Engine and ECT / Active Test / Test the Fuel Leak.*2

Perform the following test 5 times with on/off intervals of 10 seconds: Active Test / Test the Fuel Leak.*3

Allow the engine to idle for 3 minutes or more after performing the Active Test for the fifth time.

HINT:

When the Active Test "Test the Fuel Leak" is used to change the pump control mode, the actual fuel pressure inside the common rail drops below the target fuel pressure when the Active Test is off, but this is normal and does not indicate a pump malfunction.

Enter the following menus: Powertrain / Engine and ECT / DTC.

Read Current DTCs.

Clear the DTCs.

1. w/ EGR Cooler: (HILUX_TGN26 RM000000PDK0TAX.html)
   
2. w/o EGR Cooler: (HILUX_TGN26 RM000000PDK0SWX.html)
   

HINT:

It is necessary to clear the DTCs, as DTC P1604 or P1605 may be stored when air is bled from the fuel system after replacing or repairing fuel system parts.

Repeat steps *1 to *3.

Enter the following menus: Powertrain / Engine and ECT / DTC.

Read Current DTCs.

OK:

No DTCs are output.

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

Warm up the engine.

Using the 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 head.

Check that there are no leaks from any part of the fuel system when the engine is stopped. If there is fuel leakage, repair or replace parts as necessary.

Start the engine and check that there are no leaks from any part of the fuel system. If there is fuel leakage, repair or replace parts as necessary.

Disconnect the return hose from the common rail.

Start the engine and check for fuel leaks from the return pipe.
If there is fuel leakage, replace the common rail.

Connect the intelligent tester to the DLC3.

Start the engine and push the intelligent tester main switch on.

Select the Fuel Leak test from the Active Test mode on the intelligent tester.

If the intelligent tester is not available, fully depress the accelerator pedal quickly. Increase the engine speed to the maximum and maintain that speed for 2 seconds. Repeat this operation several times.

Check that there are no leaks from any part of the fuel system.

NOTICE:

A return pipe leakage of less than 10 cc (0.6 cu in.) per minute is acceptable.

Reconnect the return hose to the common rail.

Start the engine. Make sure that there are no oil leaks from the areas that were worked on.

Warm up the engine, stop the engine and wait 5 minutes. The engine oil level should be between the dipstick low level mark and full level mark.
If low, check for leakage and add oil up to the full level mark.

NOTICE:

Do not fill engine oil above the full level mark.
