ADD ENGINE COOLANT
Tighten the radiator drain cock plug by hand.
Tighten the cylinder block drain cock plug.
Fill the radiator with TOYOTA Super Long Life Coolant (SLLC) to the B line of the reservoir tank.
| Standard Capacity | |||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
|
|||||||||||||
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 consists of a combination of low phosphates and organic acids).
Please contact your TOYOTA dealer for further details.
for Cold Area Specification Vehicles:
Please contact any authorized TOYOTA dealer or repairer or another duly qualified and equipped professional for further details.
Note
Never use water as a substitute for engine coolant.
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.
Bleed air from the cooling system.
Warm up the engine until the thermostat opens. While the thermostat is open, circulate the coolant for several minutes.
Maintain the engine speed at 2500 to 3000 rpm.
Press the inlet and outlet radiator hoses several times by hand to bleed air.
CAUTION:
When pressing the radiator hoses:
Wear protective gloves.
Be careful as the radiator hoses are hot.
Keep your hands away from the radiator fan.
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 FULL line.
If the coolant level is below the FULL line, add TOYOTA SLLC to the FULL line.
BLEED AIR FROM FUEL SYSTEM
Using the hand pump mounted on the fuel filter cap, bleed air from the fuel system. Continue pumping until the pump resistance increases.
Note
The maximum hand pump pumping speed is 2 strokes per second.
The hand pump must be pushed with a full stroke during pumping.
When the fuel pressure at the supply pump inlet port reaches a saturated pressure, the hand pump resistance increases.
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.
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.
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.
Note
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.
Do not crank the engine continuously for more than 20 seconds. The battery may be discharged.
Use a fully-charged battery.
When the engine can be started, proceed to the next step.
If the engine cannot be started, bleed air again using the hand pump until the hand pump resistance increases (refer to the procedures above). Then start the engine.
Turn the engine switch off.
Connect the intelligent tester to the DLC3.
Turn the engine switch on (IG) and turn the intelligent tester on.
Clear the DTCs Click here.
Start the engine.*1
| *a | Reference (Active Test Operation) |
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 5th time.
Tech Tips
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 Click here.
Tech Tips
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.

INSPECT FOR COOLANT LEAK
Note
Before each inspection, turn the A/C switch off.
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.
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 123 kPa (1.3 kgf/cm2, 18 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.
INSPECT FOR OIL LEAK
Start the engine. Make sure that there are no oil leaks from the areas that were worked on.
INSPECT FOR FUEL LEAK
Perform the Active Test.
Connect the intelligent tester to the DLC3.
Turn the engine switch on (IG).
Turn the intelligent tester on.
Enter the following menus: Powertrain / Engine and ECT / Active Test.
Perform the Active Test.
| Intelligent Tester Display | Test Part | Control Range | Diagnostic Note |
|---|---|---|---|
| Test the Fuel Leak | Pressurize common rail interior and check for fuel leaks | Stop/Start |
|
INSPECT FOR EXHAUST GAS LEAK
If gas is leaking, tighten the areas necessary to stop the leak. Replace damaged parts as necessary.
INSPECT ENGINE IDLE SPEED
Tech Tips
For more information about the intelligent tester, refer to its operator's manual.
If an intelligent tester is not available, use a tachometer's tester probe as a substitute.
Connect the intelligent tester to the DLC3.
| *a | Front view of DLC3 |
If a tester is not available, connect the tester probe of a tachometer to terminal 9 (TAC) of the DLC3 with SST.
Inspect the idle speed.
Tech Tips
Make sure that the engine is warmed up.
Make sure that the A/C switch is off.
w/ DPF:
Make sure that PM regeneration is not being performed.
Start the engine and measure the idle speed.
| Idle Speed | |||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|

If the tester probe of a tachometer is connected to the DLC3, disconnect the tester probe together with SST from terminal 9 of the DLC3.
Disconnect the intelligent tester from the DLC3.
INSPECT ENGINE OIL LEVEL
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.
Note
Do not fill engine oil above the full level mark.
