CHARGING
Caution
Charging Recycled R-134a Refrigerant
Connect an R-134a recovery/recycling/recharging device to the vehicle and follow the device manufacturer's instructions.
Charging Preparation
1. Install the SSTs
(gas charging set).
2. Connect the tap pin side of the SST
(49 C061 004) to the air purge valve of the SST
(49C061 001).
3. Connect the SST
(49 C061 005) to the center joint of the SST
(49 C061 001).
4. Connect the SST
(49 C061 005) to the vacuum pump.
5. Connect the SST
(49 C061 004) to the refrigerant tank.
6. Place the refrigerant tank on the scale.
Regular amount of refrigerant (approximate quantity) 470 g {16.6 oz}: L.H.D.
430 g {15.2 oz}: R.H.D.
Evacuation
1. Open all the valves of the SST
(49 C061 001).
Caution
2. Start the vacuum pump and let it operate for 15 minutes.
3. Verify that high- and low-pressure side readings of the SST
(49 C061 001) are at -101 kPa {-760 mmHg, -29.9 inHg}.
Close each valve of the SST
(49 C061 001).
Airtightness Check
1. Stop the vacuum pump and wait for 5 minutes.
2. Check the high- and low-pressure side readings of the SST
(49 C061 001).
Charging New R-134a Refrigerant
1. Open the valve of the refrigerant tank.
2. Weigh the refrigerant tank to charge the suitable amount of refrigerant.
Warning
Caution
3. Open the high-pressure side valve of the SST
(49 C061 001).
4. When the low-pressure side reading increases to 0.098 MPa {1.0 kgf/cm2, 14 psi},
close the high-pressure side valve of the SST
(49 C061 001).
5. Inspect for leakage from the cooler pipe/hose connections using the SST (gas leak tester).
6. Inspect for leakage again.
Warning
7. Open the high-pressure side valve of the SST
(49 C061 001) and charge with refrigerant until the weight of refrigerant tank has decreased 250 g {8.83 oz}
from the amount in Step 2.
8. Close the high-pressure side valve of the SST
(49 C061 001).
Warning
9. Start the engine and actuate the A/C compressor.
10. Open the low-pressure side valve of the SST
(49 C061 001) and charge with refrigerant until the weight of the refrigerant tank has decreased regular amount from the amount in Step 2.
11. Close the low-pressure side valve of the SST
(49 C061 001) and the valve of the refrigerant tank.
12. Stop the engine and A/C compressor.
Leak Test
1. Inspect for leakage using the SST
(gas leak tester).
2. Inspect for leakage again.
3. Disconnect the SSTs
(49 C061 006A, 49 C061 007) from the charging valves.
4. Install the caps to the charging valves.
REFRIGERANT PRESSURE CHECK
1. Install the SSTs
(gas charging set).
2. Warm up the engine and run it at a constant 1,500 rpm.
3. Set the fan speed to MAX HI.
4. Turn the A/C switch on.
5. Set the RECIRCULATE mode.
6. Set the temperature control to MAX COLD.
7. Set the VENT mode.
8. Close all the doors and all the windows.
9. Measure the ambient temperature and the high- and low-pressure side reading of the SST
(49 C061 001).
10. Verify that the intersection of the pressure reading of the SST
(49 C061 001) and ambient temperature is in the shaded zone.
If not as specified, troubleshoot the refrigerant system. (See TROUBLESHOOTING INDEX.)
REFRIGERANT SYSTEM PERFORMANCE TEST
1. Perform refrigerant pressure check. (See REFRIGERANT PRESSURE CHECK.)
2. Place a dry-bulb thermometer in the driver-side center ventilator outlet.
3. Warm up the engine and run it at a constant 1,500 rpm.
4. Set the fan speed to MAX HI.
5. Turn the A/C switch on.
6. Set the RECIRCULATE mode.
7. Set the temperature control to MAX COLD.
8. Set the VENT mode.
9. Close all the doors and all the windows.
10. Wait until the air conditioner output temperature stabilizes.
Stabilized condition
- The A/C compressor is repeatedly turned on and off based on the A/C compressor control of center panel (manual air conditioner) or climate control unit (full-auto air condtioner).
11. Record driver-side center ventilator outlet temperature.
12. Determine and record ambient temperature.
13. Verify that the temperature reading is in the shaded zone.
