Compressor HVAC: Service Precautions

NOTICE: When servicing the compressor, keep dirt and foreign material from getting on or into the compressor parts and system. Clean tools and clean work area are important for proper service. The compressor connections and the outside of the compressor should be cleaned before any on car repairs, or before removal of the compressor. The parts must be kept clean at all times and any parts to be assembled should be cleaned with a non-petroleum based solvent and dried with air. Use only lint free cloths to wipe parts. Do not allow solvent to enter compressor or hoses.
