Mustang GT V8-4.6L SOHC VIN X (1998)
Receiver Dryer: Description and Operation
NOTE: Replacement of the suction accumulator/drier is necessary anytime a major component of the refrigerant system is replaced. Major components
include the following:
^
A/C condenser core
^
A/C compressor
^
A/C evaporator core
^
a refrigerant hose/line
An A/C evaporator core orifice or O-ring seal is not considered a major component but the A/C evaporator core orifice should be replaced whenever the
A/C compressor is replaced for lack of performance.
The suction accumulator/drier is mounted to the engine side of the dash panel to the right of the vehicle centerline. The inlet tube of the suction
accumulator/drier attaches directly to the A/C evaporator core outlet tube and the outlet tube attaches to the suction line.
After entering the inlet of the suction accumulator/drier, heavier oil-laden refrigerant contacts an internally mounted dome (which serves as an umbrella)
and drips down onto the bottom of the canister.
^
A small diameter oil bleed hole, in the bottom of the vapor return tube, allows the accumulated heavier liquid refrigerant and oil mixture to
re-enter the compressor suction line at a controlled rate.
^
As the heavier mixture passes through the small diameter liquid bleed hole, it has a second chance to vaporize and recirculate through the A/C
compressor without causing compressor damage due to slugging.
^
A fine mesh screened filter fits tightly around the bottom of the vapor return tube to filter out refrigerant system contaminant particles.
^
A desiccant bag is mounted inside the canister to absorb any moisture which may be in the refrigerant system.
^
A fitting located on the top of the suction accumulator/drier is used to attach the A/C cycling switch. A long-travel Schrader-type valve stem core
