When too much refrigerant oil more than 5-ounces accumulates in the receiver-drier this indicates that the oil bleed hole is clogged and it usually causes poor system performance.

However, the following general procedure should enable you to replace the accumulator on a vehicle if you don't have the Haynes manual. Detach the cable from the negative terminal of the battery. Disconnect the accumulator inlet and outlet lines and cap all openings to prevent contamination of the system by dirt or moisture.
NOTE: On some and later Ford Motor Company vehicles, the suction hose must be disconnected at the compressor because the line is not removable at the accumulator. If the accumulator has a pressure sensing switch, remove it and transfer to the new accumulator.
