Add coolant to the reserve tank.
Slowly pour coolant into the radiator reservoir tank until it reaches the FULL line.
| Coolant quantity |
|---|
| 1.9 liter (2.0 US qts, 1.7 Imp. qts.) |
When using the intelligent tester:
Connect the intelligent tester to the DLC3.
Turn the power switch on (IG).
On the intelligent tester, enter the following menus: Powertrain / Hybrid Control / Active Test / Activate the Water Pump.
Keep the coolant at the FULL level in the reserve tank to compensate for the drop in coolant level when the air bleeds.
| Standard |
|---|
| Air bleeding from the coolant system is completed when the noise made by the water pump becomes smaller and the circulation of coolant in the reserve tank improves. |
Tech Tips
Loud noise made by the water pump and poor circulation of coolant in the reserve tank indicates that there is air in the coolant system.
When not using the intelligent tester:
Turn the power switch on (READY). [*1]
Turn the power switch off and keep the coolant at the FULL level in the reserve tank to compensate for the drop in coolant level when the air bleeds. [*2]
Note
Be sure to turn the power switch off before adding SLLC.
Do not work on the components in the engine compartment while the vehicle is in the READY-on state because the engine is in intermittent operation.
Repeat steps [*1] and [*2] until air bleeding from the coolant system is completed.
| Standard |
|---|
| Air bleeding from the coolant system is completed when the noise made by the water pump becomes smaller and the circulation of coolant in the reserve tank improves. |
Tech Tips
Loud noise made by the water pump and poor circulation of coolant in the reserve tank indicates that there is air in the coolant system.
Add coolant to the FULL mark of the reserve tank.
ADD COOLANT (for Engine)
Tighten the radiator drain cock plug by hand.
Tighten the 2 cylinder block drain cock plugs.
Loosen the air drain cock plug on the water inlet housing.
Add TOYOTA Super Long Life Coolant (SLLC) to the radiator inlet opening until coolant overflows from the air drain cock hole. Then tighten the air drain cock plug to the water inlet housing.
Slowly fill the radiator with TOYOTA Super Long Life Coolant (SLLC).
| Item | Capacity |
|---|---|
| Engine coolant | 11.7 liters (12.4 US qts, 10.2 lmp. 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).
Contact your TOYOTA dealer for further details.
Note
Never use water as a substitute for engine coolant.
| *1 | Full Line |
Slowly pour coolant into the radiator reservoir tank until it reaches the full line.
Install the radiator cap.
Squeeze the No. 1 and No. 2 radiator hoses several times by hand, and then check the level of the coolant.
If the coolant level is low, add coolant.
Bleed air from the cooling system.
Put the engine in inspection mode Click here.
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 squeezing the No. 2 radiator hose by hand, and checking when the engine coolant starts to flow inside the hose.
Maintain the engine speed at 2500 rpm.
Squeeze the inlet and No. 1 and No. 2 radiator hoses several times by hand to bleed air.
CAUTION:
When squeezing the radiator hoses:
Wear protective gloves.
Be careful as the radiator hoses are hot.
Keep your hands away from the cooling fans.
Note
Make sure that the radiator reservoir still has some coolant in it.
If the coolant temperature gauge indicates an excessive temperature, turn off the engine and let it cool.
If there is not enough coolant, the engine may overheat or be seriously damaged.
If the radiator reservoir does not have enough coolant, perform the following: 1) stop the engine, 2) wait until the coolant has cooled down, and 3) add coolant until the reservoir is filled to the Full line.
Stop the engine and wait until the engine coolant cools down.
Add engine coolant to the full line on the radiator reservoir.
CHARGE WITH REFRIGERANT
Perform vacuum purging using a vacuum pump.
Charge with refrigerant HFC-134a (R134a).
| Standard |
|---|
| 550 to 650 g (19.4 to 22.9 oz.) |
Note
Do not turn the A/C on before charging with refrigerant. Doing so will cause the compressor to work without refrigerant, resulting in overheating of the cooler compressor.
Approximately 100 g (3.53 oz.) of refrigerant may need to be charged after bubbles disappear. The refrigerant amount should be checked by quantity, not with the sight glass.
Avoid using the gauge manifold set that had been used for vehicles with conventional compressor oil (ND-OIL 8 or equivalent) as much as possible. This will cause compressor oil remaining in the manifold to enter the vehicle, resulting in insulation performance deterioration. A gauge manifold set that had been used 3 times or less can be reused if an appropriate one is not available.
Tech Tips
Ensure that sufficient refrigerant is available to recharge the system when using a refrigerant recovery unit. Refrigerant recovery units are not always able to recover 100% of the refrigerant from an A/C system.
WARM UP ENGINE
INSPECT FOR REFRIGERANT LEAK
After recharging with refrigerant, inspect for refrigerant leaks using a halogen leak detector.
Carry out the test under the following conditions:
Turn the power switch off.
Secure good ventilation (the halogen 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)
| *1 | Inspect for Leak |
| *2 | Halogen Leak Detector |
Using a halogen leak detector, inspect for refrigerant leaks from the refrigerant lines.
| *1 | Halogen Leak Detector |
| *2 | Drain Hose |
Bring the halogen leak detector close to the drain hose with the detector's power off, and then turn the detector on.
Tech Tips
After the blower motor has stopped, let the cooling unit stand for more than 15 minutes.
Bring the halogen leak detector sensor under the drain hose.
When bringing the halogen leak detector close to the drain hose, make sure that the halogen leak detector does not react to volatile gases. If it is not possible to avoid interference from volatile gases, the vehicle should be lifted up to allow testing.
If a refrigerant leak is not detected from the drain hose, remove the blower motor control from the cooling unit. Insert the halogen leak detector sensor into the unit and perform the test.
Disconnect the pressure switch connector and leave it for approximately 20 minutes. Bring the halogen leak detector close to the pressure switch and perform the test.
INSPECT FOR COOLANT LEAK (for Inverter)
Remove the reserve tank cap.
CAUTION:
To avoid the danger of being burned, do not remove the reserve tank cap while the coolant for the inverter is still hot.
Install the radiator cap tester.
Pump the radiator cap tester to 118 kPa (1.2 kgf/ cm2, 17 psi), and then check that the pressure does not drop.
Tech Tips
If the pressure drops, check the hoses, radiator, water pump, inverter with converter, and hybrid vehicle transaxle assembly for leaks.
Reinstall the reserve tank cap.
INSPECT FOR COOLANT LEAK (for Engine)
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 performing each inspection, turn the A/C switch off.
Remove the radiator cap.
Fill the radiator with coolant and attach a radiator cap tester.
Put the engine in inspection mode Click here.
Warm up the engine.
Using the radiator cap tester, increase the pressure inside the radiator to 118 kPa (1.2 kgf/cm2, 17 psi), and check that the pressure does not drop.
If the pressure drops, check the hoses, radiator, exhaust center pipe assembly and the heater hose around the water temperature switch and engine water pump for leaks. If no external leaks are found, check the heater core, cylinder block and cylinder head.
Remove the radiator cap tester.
Install the radiator cap.
