Oil level on York compressors may be checked with compressor in vehicle. If compressor is equipped with stem-type service valves, compressor may be "isolated", thereby avoiding necessity of discharging entire system. (See COMPRESSOR ISOLATING or related paragraphs.) Frigidaire and Nippondenso 6 cylinder compressors may have to be removed from vehicle for oil check. (Refer to appropriate procedures.) After oil level is checked and adjusted, A/C system must be evacuated and recharged if compressor was not isolated.
