| Standard charge amount |
|---|
| 470 to 530 g (16.6 to 18.6 oz.) |
Note
Do not turn the A/C switch on before charging the air conditioning system with refrigerant. Doing so may cause the compressor to work without refrigerant, resulting in overheating of the compressor.
The refrigerant amount should be checked by quantity (weight).
The graph above is shown for reference only.
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 air conditioning system.
WARM UP ENGINE
Keep the A/C switch on for at least 2 minutes to warm up the compressor.
Note
To prevent damage to the compressor, be sure to warm up the compressor when turning the air conditioning on after removing and installing air conditioning system lines (including the compressor).
INSPECT FOR REFRIGERANT LEAK
After recharging the air conditioning system with refrigerant, check for refrigerant leaks using a halogen leak detector.
Carry out the test under the following conditions:
Turn the engine switch off.
Measure the pressure to make sure that there is some refrigerant remaining in the air conditioning system.
Pressure when the compressor is off: approx. 392 to 588 kPa (3.9 to 5.9 kgf/cm2, 57 to 85 psi)
Ensure good ventilation (the halogen leak detector may react to volatile gases which are not refrigerant, such as gasoline vapor and exhaust gas).
Repeat the inspection 2 or 3 times.
Remove the front outer cowl top panel sub-assembly Click here for LHD or Click here for RHD).
Remove the front bumper assembly Click here.
Remove the radiator side deflector RH Click here.
| *a | Check for leaks |
| *b | Halogen Leak Detector Sensor |
| *c | Distance between Sensor and Joint to be Checked: 10 mm or less |
| *d | Halogen Leak Detector Sensor Moving Speed: 25 to 50 mm/sec. |
How to check for refrigerant leaks in pipe joints:
Note
Gas leaking from a joint can be dissipated by even the slightest breeze. Move the halogen leak detector sensor 360° around each joint instead of keeping it in one spot when checking.
Using a halogen leak detector, check for refrigerant leaks at the pipe joints shown in the illustration.
| *a | Area to be Checked | *b | Service Valve (High) |
| *c | Service Valve (Low) | *d | Pipe Joint |
| *e | Air Conditioner Pressure Sensor Joint | *f | Cooler Expansion Valve Joint |
| *g | Condenser Joint (Inlet) | *h | Condenser Joint (Outlet) |
| *i | Compressor Joint (Inlet) | *j | Compressor Joint (Outlet) |
Tech Tips
After the blower motor has stopped, leave the cooling unit for more than 15 minutes.
Disconnect the pressure sensor connector and leave it for approximately 20 minutes.
When checking for leaks, the presence of oily dirt at a joint can indicate a leak.
| Standard |
|---|
| There are no refrigerant leaks from the joints. |
If refrigerant is leaking, disconnect the leaking joint and visually check for the cause, such as the presence of foreign matter.
| *1 | Drain Cooler Hose |
| *a | Halogen Leak Detector |
Bring the halogen leak detector sensor close to the drain cooler hose with the detector turned off, and then turn the detector on.
Note
Keep water away from the halogen leak detector to prevent malfunction.
Tech Tips
After the blower motor has stopped, leave the cooling unit for more than 15 minutes.
When bringing the halogen leak detector sensor close to the drain cooler 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 checking for leaks.
| Standard |
|---|
| Refrigerant is not leaking from the drain cooler hose. |
If refrigerant is leaking, check for refrigerant leaks from the No. 1 cooler evaporator sub-assembly.
Remove the blower motor with fan sub-assembly Click here.
| *1 | No. 1 Cooler Evaporator Sub-assembly |
| *a | Halogen Leak Detector |

INSPECT ENGINE OIL LEVEL
Warm up the engine, stop it and wait 5 minutes. The engine oil level should be between the engine oil level dipstick low level mark and full level mark.
If the engine oil level is low, check for leakage and add engine oil up to the full level mark.
Note
Do not add engine oil to above the full level mark.
INSPECT ENGINE COOLANT LEVEL IN RESERVOIR
Check that the engine coolant level is between the low and full lines when the engine is cold.
If the engine coolant level is low, check for leaks and add "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 to the full line.
Note
Do not substitute plain water for engine coolant.
INSPECT FOR FUEL LEAK

Connect the GTS to the DLC3.
Turn the engine switch on (IG) and turn the GTS on.
Note
Do not start the engine.
Enter the following menus: Powertrain / Engine / Active Test / Control the Fuel Pump / Speed.
Check for pressure in the fuel tube sub-assembly from the fuel pipe. Check that sounds of fuel flowing from the fuel tank can be heard. If no sounds can be heard, check the integration relay, fuel pump, ECM and wiring connectors.
Inspect for fuel leaks.
Check that there are no fuel leaks from the fuel system after doing any maintenance or repairs. If there is a fuel leak, repair or replace parts as necessary.
Turn the engine switch off.
Disconnect the GTS from the DLC3.
INSPECT FOR COOLANT LEAK
CAUTION:
Do not remove the radiator cap sub-assembly 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.
Fill the radiator with engine coolant and attach a radiator cap tester.
Warm up the engine.
Using a radiator cap tester, increase the pressure inside the radiator to 118 kPa (1.2 kgf*cm, 17 psi), and check that the pressure does not drop.
If the pressure drops, check the hoses, radiator assembly and engine water pump assembly for leaks. If no external leaks are found, check the heater core, cylinder block and cylinder head.
