REFRIGERANT SYSTEM SERVICE PROCEDURES
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).
•
If there is no leakage, go to Step 3.
•
If leakage is found at a loose joint, tighten the joint, then go to next step.
2. Inspect for leakage again.
•
If there is no leakage after tightening the joint, go to next step.
•
If there is still leakage at the same joint, discharge the refrigerant and then repair the joint. Repeat the
charging procedure from evacuation.
3. Disconnect the SSTs (49 C061 006A, 49 C061 007) from the charging valves.
4. Install the caps to the charging valves.

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).
