ACDelco Professional A/C Compressors pump refrigerant through the system and are the ideal high-quality replacement for your GM and non-GM vehicle. 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 draws in cool refrigerant gas from the evaporator and pumps it to a much higher pressure. The high-pressure gas travels on to the condenser. The compressor is lubricated by refrigerant oil. These Professional, premium aftermarket replacement components are manufactured to meet or exceed your expectations for fit, form and function.

ACDelco®, a brand of GM Customer Care and Aftersales, is a global automotive manufacturer of premium replacement parts for almost all vehicle systems as well as off-road, industrial, and marine equipment.
