Part Description
This Grade A A/C air compressor was removed from a 2007 GM Trucks Silverado 1500 with 93,000 miles. The compressor is designed for 4.3L engines and fits both classic and new style configurations. It has been thoroughly inspected by our technicians and is currently on the shelf ready for immediate shipment.
The A/C compressor is the heart of your vehicle’s air conditioning system, pressurizing and circulating refrigerant throughout the system. Common reasons for replacement include internal bearing failure, clutch problems, refrigerant leaks from worn seals, or electrical issues with the clutch coil. When your A/C stops blowing cold air or makes grinding noises, the compressor is often the culprit.
