COMPRESSOR OIL DRAIN PROCEDURE
| CAUTION | Be certain to adjust the refrigerant system oil level when replacing an A/C compressor. Failure to properly drain and measure the refrigerant oil from the A/C compressor can prevent the A/C system from operating as designed and cause serious compressor damage. |
The A/C compressor is filled with refrigerant oil from the factory. Use the following procedure to drain and measure refrigerant oil from the A/C compressor.
- Drain all of the refrigerant oil from the old A/C compressor into a clean measured container.
- Drain all of the refrigerant oil from the new A/C compressor into a clean measured container.
- Refill the new A/C compressor with the same amount of refrigerant oil that was drained out of the old compressor. Use only clean refrigerant oil of the type recommended for the A/C compressor in the vehicle.
- Install the new A/C compressor onto the engine. See «INSTALLATION»(ref-306135-S17764719442008120900000) .
Scheme 52
The A/C receiver/drier (1) stores unnecessary refrigerant, filters the refrigerant, helps remove moisture from the refrigerant and retains any refrigerant vapor that may leave the A/C condenser (2) until it becomes a liquid. The A/C receiver/drier is installed on the high-side of the A/C system and is connected directly to the left end of the A/C condenser by a bolt (3). The A/C receiver/drier can be serviced separately from the A/C condenser.
