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).
Slowly pour coolant into the radiator reservoir until it reaches the F line.
Install the reservoir cap.
Press the No. 1 and No. 2 radiator hoses several times by hand, and then check the coolant level. If the coolant level is low, add coolant.
Install the radiator cap.
Set the air conditioning as follows while warming up the engine.
| Item | Condition |
|---|---|
| Fan speed | Any setting except off |
| Temperature | Toward WARM |
| Air conditioning switch | Off |
Start the engine and warm it up until the thermostat opens.
Tech Tips
The thermostat opening timing can be confirmed by pressing the No. 2 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.
Note
Make sure that the radiator reservoir still has some coolant in it.
Pay attention to the needle of the water temperature meter. Make sure that the needle does not show an abnormally high temperature.
If there is not enough coolant, the engine may burn out or overheat.
Immediately after starting the engine, if the radiator reservoir does not have any coolant, perform the following: 1) stop the engine, 2) wait until the coolant has cooled down, and 3) add coolant until the coolant is filled to the F line.
Run the engine at 2000 rpm until the coolant level has stabilized.
Press the No. 1 and No. 2 radiator hoses several times by hand to bleed air.
CAUTION:
Wear protective gloves. Hot areas on the parts may injure your hands.
Be careful as the radiator hoses are hot.
Keep your hands away from the fan.
Stop the engine, and wait until the engine coolant cools down to ambient temperature.
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.
Check that the coolant level is between the F and L lines.
If the coolant level is below the L line, repeat all of the procedures above.
If the coolant level is above the F line, drain coolant so that the coolant level is between the F and L lines.
INSPECT FOR FUEL LEAK
Make sure that there are no fuel leaks after performing maintenance on the fuel system.
Connect the GTS to the DLC3.
Turn the ignition switch to ON and turn the GTS on.
Note
Do not start the engine.
Enter the following menus: Powertrain / Engine and ECT / Active Test / Control the Fuel Pump / Speed.
Check that there are no leaks from the fuel system.
If there are fuel leaks, repair or replace parts as necessary.
Turn the ignition switch off.
Disconnect the GTS from the DLC3.
INSPECT FOR COOLANT LEAK
CAUTION:
To avoid being burned, do not remove the radiator reservoir cap while the engine and radiator are still hot. Thermal expansion may cause hot engine coolant and steam to blow out from the radiator.
Fill the radiator with engine coolant, and then attach a radiator cap tester.
Warm up the engine.
Using the radiator cap tester, increase the pressure inside the radiator to 123 kPa (1.3 kgf/cm2, 18 psi), and then check that the pressure does not drop.
If the pressure drops, check the hoses, radiator and engine water pump for leakage. If there are no signs or traces of external engine coolant leakage, check the heater core, cylinder block and head.
INSPECT FOR OIL LEAK
Start the engine. Make sure that there are no oil leaks from the area that was worked on.
INSPECT FOR EXHAUST GAS LEAK
If gas is leaking, tighten the areas necessary to stop the leak. Replace damaged parts as necessary.
CHECK ENGINE OIL LEVEL
Warm up the engine, and then stop the engine and wait for 5 minutes.
Check that the engine oil level is between the low level and full level marks on the dipstick.
If low, check for leakage and add oil up to the full level mark.
Note
Do not fill engine oil above the full level mark.
Tech Tips
A certain amount of engine oil will be consumed while driving. In the following situations, oil consumption may increase, and engine oil may need to be refilled in between oil maintenance intervals.
When the engine is new, for example directly after purchasing the vehicle or after replacing the engine.
If low quality oil or oil of an inappropriate viscosity is used.
When driving at high engine speed or with a heavy load, (when towing, or), when driving while accelerating or decelerating frequently.
When leaving the idling for a long time, or when driving frequently through heavy traffic.
When judging the amount of oil consumption, keep in mind that the oil may have become diluted, making it difficult to judge the true level accurately.
CHARGE REFRIGERANT
Perform vacuum purging using a vacuum pump.
Charge refrigerant HFC-134a (R134a).
| Condenser Core Thickness | Air Conditioning Type | Cool Box | Refrigerant Charging Amount |
|---|---|---|---|
| 22 mm (0.866 in.) | w/o Rear Cooler | w/ Cool Box | 870 +/-30 g (30.7 +/-1.1 oz.) |
| w/o Cool Box | 870 +/-30 g (30.7 +/-1.1 oz.) | ||
| w/ Rear Cooler | w/ Cool Box | 1010 +/-30 g (35.6 +/-1.1 oz.) | |
| w/o Cool Box | 960 +/-30 g (33.9 +/-1.1 oz.) | ||
| 16 mm (0.630 in.) | w/o Rear Cooler | w/ Cool Box | 770 +/-30 g (27.2 +/-1.1 oz.) |
| w/o Cool Box | 770 +/-30 g (27.2 +/-1.1 oz.) | ||
| w/ Rear Cooler | w/ Cool Box | 970 +/-30 g (34.2 +/-1.1 oz.) | |
| w/o Cool Box | 920 +/-30 g (32.5 +/-1.1 oz.) |
Note
Do not operate the cooler compressor before charging refrigerant as the cooler compressor will not work properly without any refrigerant, and will overheat.
Approximately 200 g (7.05 oz.) of refrigerant may need to be charged after bubbles disappear. The refrigerant amount should be checked by measuring its quantity, and not with the sight glass.
WARM UP ENGINE
Warm up the engine at less than 1850 rpm for 2 minutes or more after charging the refrigerant.
Note
Be sure to warm up the compressor when turning the A/C switch is on after removing and installing the cooler refrigerant lines (including the compressor), to prevent damage to the compressor.
CHECK FOR REFRIGERANT GAS LEAK
After recharging the refrigerant gas, check for refrigerant gas leakage using a halogen leak detector.
Perform the operation under these conditions:
Stop the engine.
Secure good ventilation (the halogen leak detector may react to volatile gases other than refrigerant, such as evaporated gasoline or exhaust gas).
Repeat the test 2 or 3 times.
Make sure that some refrigerant remains in the refrigeration system. When compressor is off: approximately 392 to 588 kPa (4.0 to 6.0 kgf/cm2, 57 to 85 psi).
Using a halogen leak detector, check the refrigerant line for leakage.
If a gas leak is not detected on the drain hose, remove the blower motor control (blower resistor) from the cooling unit. Insert the halogen leak detector sensor into the unit and perform the test.
Disconnect the connector and wait for approximately 20 minutes. Bring the halogen leak detector close to the pressure switch and perform the test.

INSPECT CO/HC
Tech Tips
This check is to determine whether or not the idle CO/HC concentration complies with regulations.
Start the engine.
Run the engine at 2500 rpm for approximately 180 seconds.
Insert the CO/HC meter testing probe at least 40 cm (1.31 ft) into the tailpipe during idling.
Immediately check the CO/HC concentration during idling and/or at 2500 rpm.
Tech Tips
When carrying out the 2 tests (idling and 2500 rpm), the measurement orders are prescribed by the applicable local regulations.
If the CO/HC concentration does not comply with regulations, perform troubleshooting in the order given below.
Check the air fuel ratio sensor operation Click here and heated oxygen sensor operation Click here.
See the table below for possible causes, and then inspect and correct the corresponding causes if necessary.
| CO | HC | Symptom | Causes |
|---|---|---|---|
