| Standard capacity |
|---|
| 9.8 liters (10.4 US qts, 8.6 Imp. 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 consists of a combination of low phosphates and organic acids).
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.
Tech Tips
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.
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 F line.
If the coolant level is below the F line, add TOYOTA SLLC to the F line.
BLEED AIR FROM FUEL SYSTEM
Using the hand pump mounted on the fuel filter cap, bleed the air from the fuel system. Continue pumping until the pump resistance increases.
Note
Hand pump pumping speed: Max. 2 strokes/ sec.
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.
Start the engine.
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 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 Click here.
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.
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.

Repeat the step above several times.
Stop the engine.
Check for foaming or emulsification. If the system has to be bled twice because of forming or emulsification, check for fluid leaks in the system.
Check the fluid level.
INSPECT POWER STEERING FLUID LEVEL
Keep the vehicle level.
With the engine stopped, check the power steering fluid level in the oil reservoir. If necessary, add power steering fluid.
| Power steering fluid (for TMT made) |
|---|
| "TEXAMATIC 1888" or equivalent |
| (for TSAM made) |
| "TEXAMATIC 1322S" or equivalent |
Tech Tips
If the fluid is hot, check that the fluid level is within the HOT range on the oil reservoir. If the fluid is cold, check that the fluid level is within the COLD range.
Start the engine and run it at idle.
Turn the steering wheel to the left or right full lock position, and then the wheel to the opposite full lock position. Repeat several times to raise fluid temperature.
| Standard fluid temperature |
|---|
| 75 to 80°C (167 to 176°F) |
Check for foaming or emulsification. If foaming or emulsification is identified, bleed air from the power steering system.
With the engine idling, measure the fluid level in the oil reservoir.
Stop the engine.
Wait a few minutes and remeasure the fluid level in the oil reservoir.
| Maximum fluid level increase |
|---|
| 5 mm (0.20 in.) |

INSPECT FOR OIL LEAK
INSPECT FOR COOLANT LEAK
Note
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 to the radiator reservoir.
Warm up the engine.
Using the radiator cap tester, increase the pressure inside the radiator to 118 kPa (1.2 kgf/cm2,17.1 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 cylinder block and head.
INSPECT FOR EXHAUST GAS LEAK
If gas is leaking, tighten the problem areas to stop the leak. Replace damaged parts as necessary.
INSPECT FOR FUEL LEAK
CAUTION:
During Active Test mode, engine speed becomes high and combustion noise becomes loud, so pay attention.
During Active Test mode, fuel becomes high-pressured. Be extremely careful not to expose your eyes, hands, or body to escaped fuel.
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.
Note
A return pipe leakage of less than 10 cc (0.6 cu in.) per minute is acceptable.
If there is fuel leakage, repair or replace parts as necessary.
Reconnect the return hose to the common rail.
INSPECT ENGINE IDLE SPEED AND MAXIMUM SPEED
Tech Tips
For more information about the intelligent tester, refer to its operator's manual.
If a intelligent tester is not available, use a tachometer's tester probe as a substitute.

Make sure that the A/C switch is off.
Start the engine and measure the idle speed.
| Standard idle speed |
|---|
| 700 to 800 rpm |
Inspect the maximum speed.
Start the engine.
Fully depress the accelerator pedal.
Measure the maximum speed.
| Maximum Speed |
|---|
| 4450 to 4750 rpm |

Disconnect the intelligent tester from the DLC3.
INSPECT ENGINE OIL LEVEL
Warm up the engine, stop the engine and wait 5 minutes. The oil level should be between the dipstick's low and full level marks.
