These Compressors are 100% New not remanufactured and feature a show quality chrome finish with chrome clutch cover. They are 12 volt and compatible with R-12 and R-134 refrigerant. This compressor features a black powdercoated double v-belt pulley but we offer serpentine pulley compressors in our store. This is a great upgrade from the early style York and Tecumseh compressors. The compressor contains assembly oil only. The A/C system must be properly flushed and cleaned before installation of the compressor.
