A-Premium PXV16 Air Conditioner Compressor with Clutch for 2005–2011 GM Cars — 5-Groove Pulley, Pre-filled PAG46

This replacement air conditioning compressor arrives ready to install, including the clutch assembly and the correct amount of oil (160ml ±20ml). Built as a direct-fit aftermarket part, it matches multiple OEM numbers and fits a range of 2005–2011 GM small cars and crossovers. The unit is intended to restore compressor function and integrate with existing A/C systems when the correct vehicle fitment is confirmed.

How do I know this compressor fits my vehicle?

Confirm fitment by comparing the listed part numbers and the compressor’s mounting and pulley layout with your existing unit. The listing includes many OEM reference numbers to simplify matching, and photos should be checked against your current compressor before ordering.

• Compatible models: Chevrolet Cobalt, HHR; Pontiac G5; Saturn Ion (years and engine sizes listed).
• Reference part numbers: 15830956, 19130592, 20772560, and others included.
• Pulley: 5-groove pulley geometry to match serpentine belt routing.
• Confirm visually: mounting points, clutch diameter, and electrical connector match.

What are the key technical specifications of this A/C compressor?

The compressor uses a PXV16 design and ships prefilled with PAG46 lubricant in a precise quantity to help ensure lubrication at installation. It comes supplied with the clutch assembly, so you receive a full compressor-and-clutch kit rather than a partial component.

• Compressor type: PXV16 for common GM systems.
• Oil type and amount: PAG46, prefilled 160ml with ±20ml tolerance.
• Pulley grooves: 5, compatible with many GM accessory belts.
• Clutch included: yes — installed and aligned for immediate assembly.

What should I expect during installation and maintenance?

Installation requires basic A/C system service: evacuate refrigerant, remove the old compressor, replace with the new unit, and recharge the system to manufacturer refrigerant specifications. Use proper A/C service equipment and follow local laws for refrigerant handling; if you are not experienced, have a certified technician perform the work.

• Pre-install steps: verify fitment, recover refrigerant, and inspect hoses/receiver-drier.
• Installation: torque fasteners to factory specs and connect the electrical clutch lead.
• Post-install: vacuum, leak test, and charge with the correct refrigerant and oil level.
• Service reminder: replace or inspect the receiver-drier and expansion device when replacing compressors.

Who is this for? This A-Premium AC compressor kit is suited for DIYers with moderate mechanical experience and professional mechanics replacing failed compressors on the specified Chevrolet, Pontiac, and Saturn models. It’s also a practical choice for fleet maintenance where OE-fit reliability and an included clutch reduce parts sourcing time. Always double-check the compatibility list and physical match to your current compressor before purchase to avoid returns.
