Note
Before performing each inspection, turn the A/C switch off.
Fill the radiator assembly with engine coolant and attach a radiator cap tester.
Warm up the engine.
Using a radiator cap tester, increase the pressure inside the radiator assembly 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 assembly and engine water pump assembly for leaks. If no external leaks are found, check the heater core, cylinder block and cylinder head.

INSPECT FOR COOLANT LEAK (for 2GR-FE)
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 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 and water pump for leaks. If no external leaks are found, check the heater core, cylinder block and cylinder head.
CHARGE AIR CONDITIONING SYSTEM WITH REFRIGERANT
Perform vacuum purging using a vacuum pump or appropriate equipment.
Charge the air conditioning system with refrigerant.
| Refrigerant type |
|---|
| HFC-134a (R134a) |
| *a | Sub-cool System | *b | High Pressure |
| *c | Refrigerant Amount | *d | Standard charge amount |
| *e | Charge additional 100 g (3.5 oz.) | *f | Point where bubbles disappear |
| *g | Mean value in proper range | *h | Overcharged |
| Standard charge amount |
|---|
| 450 to 550 g (15.9 to 19.4 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).
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.

| *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.
