Note
When replacing the injectors (including shuffling the injectors between the cylinders), common rail or cylinder head, it is necessary to replace the injection pipes with new ones.
When replacing the fuel supply pump, common rail, cylinder block, cylinder head, cylinder head gasket or timing gear case, it is necessary to replace the fuel inlet pipe with a new one.
After removing the injection pipes, clean them with a brush and compressed air.

ADD ENGINE COOLANT
Pour coolant into the radiator until it overflows.
| Capacity | ||||||||
|---|---|---|---|---|---|---|---|---|

Note
Do not substitute plain water for engine coolant.
Tech Tips
Use of improper coolants may damage the engine cooling system.
Use only Toyota Super Long Life Coolant or similar high quality ethylene glycol based non-silicate, non-amine, non-nitrite, and 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).
Check the coolant level inside the radiator by squeezing the inlet and outlet radiator hoses several times by hand.
If the coolant level goes down, add coolant.
Install the radiator cap securely.
Slowly pour coolant into the radiator reservoir until it reaches the FULL line.
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 2000 to 2500 rpm.
Squeeze the inlet and outlet radiator hoses several times by hand while warming up the engine to bleed the air.
CAUTION:
When squeezing the radiator hoses:
Wear protective gloves.
Be careful as the radiator hoses are hot.
Keep your hands away from the fan.
Stop the engine and wait until the coolant cools down.
Remove the radiator cap and check the coolant level inside the radiator.
If the coolant level is below the full level, repeat the operation until the coolant level remains at the full level.
Check the coolant level inside the radiator reservoir tank again.
If it is below the full level, add coolant.
ADD ENGINE OIL
Add fresh oil and install the oil filler cap.

INSPECT FOR FUEL LEAK
Perform the Active Test.
Connect the intelligent tester to the DLC3.
Turn the ignition switch to ON.
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 the common rail interior and check for fuel leaks | Stop/Start |

INSPECT FOR COOLANT LEAK
Remove the radiator cap.
CAUTION:
To avoid the danger of being burned, do not remove the radiator cap while the engine and radiator are still hot. Thermal expansion will cause hot engine coolant and steam to blow out from the radiator.
| *1 | Radiator Cap Tester |
Fill the radiator with coolant and attach a radiator cap tester.
Warm up the engine.
Pump it 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 and water pump for leakage. If there are no signs of external coolant leakage, check the heater core, cylinder block and head.
Reinstall the radiator cap.
INSPECT FOR OIL LEAK
Warm up the engine and inspect for oil leak.
