CAUTION:
Do not remove the radiator cap sub-assembly, radiator drain cock plug or engine drain plug while the engine and radiator are still hot. Pressurized, hot engine coolant and steam may be released and cause serious burns.
Note
Do not substitute plain water for engine coolant.
Add engine coolant.
| Standard capacity |
|---|
| 14.2 liters (15.0 US qts, 12.5 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 is a combination of low phosphates and organic acids).
Check the coolant level inside the radiator by squeezing the inlet radiator hose and outlet radiator hose several times by hand. If the coolant level goes down, add coolant.
Install the radiator cap sub-assembly.
Slowly pour coolant into the radiator reservoir until it reaches the F line.
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 a speed between 2500 and 3000 rpm.
Press the inlet and outlet radiator hoses several times by hand to bleed air.
Note
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.
Remove the radiator cap sub-assembly and check the coolant level.
If the coolant level has dropped, add coolant.
Check the coolant level inside the radiator reservoir assembly again.
If the coolant level is below the F line, add coolant to F line.
ADD POWER STEERING FLUID
BLEED AIR FROM FUEL SYSTEM
Loosen the bleeder plug.
|
Bleeder Plug |
Note
Make sure that the drain plug and bleeder plug of the filter on the fuel tank side are closed.
Bleed air using the priming pump on the fuel tank side.
Note
Place a container, etc. underneath the fuel filter to prevent fuel from spraying.
The hand pump must be pushed with a full stroke during pumping.
The maximum hand pump pumping speed is 2 strokes per second.
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.
Tighten the bleeder plug.
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.
Tech Tips
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 ignition switch off.
Connect the intelligent tester to the DLC3.
Turn the ignition switch to ON and turn the intelligent tester on.

INSPECT FOR COOLANT LEAK
CAUTION:
Do not remove the radiator cap while the engine and radiator are still hot. Pressurized, hot engine coolant and steam may be released and cause serious burns.
Note
Before each inspection, turn the A/C switch off.
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 137 kPa (1.4 kgf/cm2, 20 psi), and check that the pressure does not drop.
If the pressure drops, check the hoses, radiator assembly and engine water pump for leaks. If no external leaks are found, check the heater core, cylinder block and cylinder head.
INSPECT OIL LEAK
Start the engine. Make sure that there are no oil leaks from the areas that were worked on.
BLEED AIR FROM POWER STEERING SYSTEM

Turn the steering wheel.
With the engine idling, turn the steering wheel left or right to the full lock position and keep it in that position for 2 to 3 seconds, then turn the steering wheel to the opposite full lock position and keep it there for 2 to 3 seconds (*1).
Repeat this procedure (*1) several times.
Stop the engine.
Check for foaming or emulsification.
Tech Tips
If the system has to be bled twice because of forming or emulsification, be sure to check for fluid leaks in the system.
Check the fluid level Click here.
CHECK POWER STEERING FLUID LEVEL
Keep the vehicle level.
With the engine stopped, check the fluid level in the fluid reservoir.
If necessary, add fluid.
| Fluid |
|---|

If the fluid is hot, check that the fluid level is within the HOT range on the fluid 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 from lock to lock several times to raise fluid temperature.
| Fluid temperature |
|---|
| 50 to 60°C (122 to 140°F) |
