Description
0012302911 – Mercedes-Benz A/C Compressor, repair kit
The A/C Compressor is the central component of the vehicle’s air conditioning system, functioning as a pump to pressurize and circulate refrigerant (R134a). This specific unit is a variable displacement swash-plate type compressor which adjusts its output based on cooling demand to improve fuel efficiency. It is driven by the engine’s serpentine belt via a 6-groove, 110mm diameter pulley and converts low-pressure refrigerant gas from the evaporator into high-pressure, high-temperature gas sent to the condenser.
