REMOVAL & INSTALLATION
Any time a major component of the air conditioning system is replaced, it is necessary to replace the suction accumulator/drier. A major component would be the condenser, compressor, evaporator or a refrigerant hose/line. A fixed orifice tube or O-ring is not considered a major component but the orifice tube should be replaced whenever the compressor is replaced for lack of performance.
The accumulator/drier should also be replaced, if one of the following conditions exist:
The compressor oil from vehicles equipped with an FX-15 compressor may have a dark color while maintaining a normal oil viscosity. This is normal for this compressor because carbon from the compressor piston rings may discolor the oil.
When replacing the suction accumulator/drier, the following procedure must be used to ensure that the total oil charge in the system is correct after the new accumulator/drier is installed.
- Drain the oil from the removed accumulator/drier into a suitable measuring container. It may be necessary to drill one or two 1 / 2 in. (13mm) holes in the bottom of the old accumulator/drier to ensure that all the oil has drained out.
- Add the same amount of clean new refrigerant oil plus two oz. to the new accumulator/drier. Use only the proper type of oil for the vehicle being serviced.
See Figure 1
- Disconnect the negative battery cable.
- Discharge the refrigerant from the air conditioning system according to the proper procedure.
- On 2.3L engine equipped vehicles, remove the speed control servo, if equipped.
- Disconnect the suction hose at the compressor. Cap the hose and compressor to prevent the entrance of dirt and moisture.
- Disconnect the accumulator/drier inlet tube from the evaporator core outlet. Use two wrenches to prevent component damage.
- Disconnect the wire harness from the pressure switch on top of the accumulator/drier.
- Remove the screw holding the accumulator/drier in the accumulator bracket and remove the accumulator/drier.
- Position the accumulator/drier to the vehicle and route the suction hose to the compressor.
- Using a new O-ring lubricated with clean refrigerant oil, connect the accumulator/drier inlet tube to the evaporator core outlet. Tighten the connection using a back-up wrench to prevent component damage.
- Install the screw in the accumulator/drier bracket
- Using a new O-ring lubricated with clean refrigerant oil, connect the suction hose to the compressor.
- On 2.3L engine equipped vehicles, install the speed control servo, if equipped.
- Leak test, evacuate and charge the air conditioning system. Observe all safety precautions.
- Check the system for proper operation.
