REMOVAL & INSTALLATION
See Figure 1
Replacement of the suction accumulator/drier is necessary anytime a major component of the A/C system is replaced. A major component includes condenser, compressor, evaporator core or a refrigerant hose/line. An orifice tube or O-ring is not considered a major component, but the orifice tube should be replaced whenever the compressor is replaced.
In addition, the accumulator/drier should also be replaced if one of the following conditions exists:
- Discharge the A/C system using an approved Recycling/Recovery unit. Refer to Routine Maintenance .
- Disconnect the inlet and outlet lines at the accumulator. Cap the ends to prevent any dirt or moisture from entering the system.
- Disconnect the wiring harness connector for the A/C cycling switch on top of the accumulator/drier (if equipped).
- Remove the bracket retaining accumulator in place and remove the accumulator.
- Drain the oil from the accumulator/drier into a suitable measuring container.
It may be necessary to drill two1/2(12.5mm) holes into the bottom of the accumulator/drier to ensure that all of the oil has drained out.
- Add the same amount of new refrigerant oil plus two fluid ounces to the new accumulator/drier. Use only oil specified for vehicle application.
- Position the accumulator/drier in the vehicle, then route the suction hose to the compressor.
- Using new O-rings, lubricated with clean refrigerant oil, connect the accumulator/drier inlet tube to the evaporator.
- Evacuate, charge and leak test the system. See Routine Maintenance .
- Check the system for proper operation.
