Draining Procedure
WARNING: This page is about a different car, the 2007 Suzuki XL7. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Drain and measure as much of the refrigerant oil as possible from the removed compressor.
- Drain the oil from both the suction and discharge ports of the removed compressor into a clean, graduated container.
Rotate the compressor shaft to assist in draining the compressor.
- Measure and record the amount of oil drained from the removed compressor.
This measurement will be used during installation of the replacement compressor.
NOTE: During the oil removal procedure, the condition of the oil should be evaluated. Compressor oil never breaks down unless something is wrong with the compressor or air conditioning (A/C) system. If one or more of the following conditions exist, replace the compressor and receiver dehydrator. - Inspect the Polyalkylene glycol (PAG) oil for the following conditions:
- The color of the oil is dark brown or black.
- There is a presence of foreign substances, metal fillings, etc. in the oil.
If the receiver-dehydrator is not replaced, damage to A/C compressor will occur.
- Properly discard the used refrigerant oil.
