| Standard 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).
Loosen the bleeder plug of the outlet housing.
When air is bled and the coolant drains out, firmly tighten the bleeder plug.
Add coolant up to the B line mark in the radiator reservoir and install the reservoir cap.
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.
After the engine cools down, check that the coolant level is between the LOW and FULL level marks.
BLEED AIR FUEL LINE
Using the hand pump mounted on the fuel filter cap, bleed 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.
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 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.

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.

CHARGE REFRIGERANT (w/ Air Conditioning System)
Perform vacuum purging using a vacuum pump.
Charge with refrigerant HFC-134a (R134a).
| Standard |
|---|
| Single A/C |
| 520 to 580g (18.3 to 20.5 oz.) |
| Dual A/C |
| 670 to 730g (23.0 to 25.7 oz.) |
Note
Do not operate the cooler compressor before charging refrigerant as the cooler compressor does not work properly without any refrigerant, which causes the compressor to overheat.
Approximately 100 g (3.5 oz.) of refrigerant may need to be charged after bubbles disappear. The refrigerant amount should be checked by quantity, and not with the sight glass.
Tech Tips
Prepare a service can to recharge refrigerant if using the refrigerant gas collected with the freon collection/recycling device because the collective rate of the device is approximately 90%.
INSPECT FOR COOLANT LEAK
CAUTION:
Do not remove the radiator cap while the engine and radiator are still hot. Hot, pressurized 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.
Warm up the engine.
Using a radiator cap tester, increase the pressure inside the radiator to 137 kPa (1.4 kgf/cm2, 19.9 psi), and check that the pressure does not drop.
Tech Tips
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 cylinder head.
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 / ECD / Active Test.
Perform the Active Test.
| Intelligent Tester Display | Test Part | Control Range | Diagnostic Notes |
|---|---|---|---|
| Test the Fuel Leak | Pressurize common rail interior and check for fuel leaks | Stop/Start |

INSPECT REFRIGERANT LEAK (w/ Air Conditioning System)
After recharging refrigerant gas, check for leakage of refrigerant gas using a halogen leak detector.
Carry out the test under the following conditions:
Stop the engine.
Secure good ventilation (the gas leak detector may react to volatile gases which are not refrigerant, such as evaporated gasoline and exhaust gas).
Repeat the test 2 or 3 times.
Make sure that there is some refrigerant remaining in the refrigeration system.
When the compressor is off: approx. 392 to 588 kPa (4 to 6 kgf/cm2, 57 to 85 psi)
Using a gas leak detector, check for leakage of the refrigerant line.
Bring the gas leak detector close to the drain hose with the detector's power off.
Tech Tips
After the blower motor has stopped, let the cooling unit stand for more than 15 minutes.
Bring the gas leak detector sensor under the drain hose.
When bringing the gas leak detector close to the drain hose, make sure that the gas leak detector does not react to volatile gases.
If such reaction is unavoidable, the vehicle must be lifted up.
If a gas leak is not detected on the drain hose, remove the blower motor control from the cooling unit. Insert the gas leak detector sensor into the unit and perform the test.
Disconnect the pressure switch connector and leave it for approximately 20 minutes. Bring the gas leak detector close to the pressure switch and perform the test.
