About this product

GM Genuine Parts A/C Compressors are designed, engineered, and tested to rigorous standards, and are backed by General Motors. These compressors pump refrigerant through the system. The compressor is typically engine driven via the accessory belt, and a clutch on the compressor is used to engage and disengage the compressor. Hybrid vehicles are typically equipped with an electric motor driven compressor. The compressor is lubricated by refrigerant oil. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE).
