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 FUEL LEAK

Check for pressure in the fuel tube sub-assembly from the fuel line. Check that sounds of fuel flowing from the fuel tank assembly 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 ignition switch off.
Disconnect the intelligent tester from the DLC3.
INSPECT FOR COOLANT LEAK
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 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.

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 |

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.
