It is a Sanden SD7H15 Super Heavy Duty style compressor that pressurizes and circulates R134a refrigerant through the vehicle's A/C system to produce cold air. This compressor typically features a 12-groove serpentine clutch, 12V Packard connector, and comes pre-filled with 240cc of PAG 100 oil. It is commonly replaced when the original compressor fails due to internal wear, clutch failure, or insufficient cooling performance.
