ILONPA New AC compressor with integrated clutch restores air conditioning performance for compatible Chevrolet, GMC, Cadillac and Hummer V8/V6 models listed.

If your vehicle’s AC blows warm air, a failing compressor or seized clutch is often the cause. This ILONPA replacement compressor (10S20F type) ships prefilled with 180ml PAG46 oil and uses a four-groove 110mm pulley, making it a direct-fit service part for a range of Chevrolet Express, Suburban, Tahoe, Cadillac Escalade, GMC Yukon XL/Savana and select Hummer H2 years and engines. The unit is built to meet OE-style specifications and includes the clutch assembly to simplify swap-out when the compressor is the source of the issue.

Which models and engines is this compressor compatible with?

This ILONPA compressor fits many GM full-size vans, SUVs and trucks from roughly 2000–2014, but exact fit depends on engine and model year. Use your vehicle details or a fitment tool to confirm compatibility before purchase.

• Chevrolet Express 1500/2500/3500 (various years and 4.8L, 5.3L, 6.0L, 6.0L/6.2L configurations)

What are the key specifications and what comes prefilled?

The compressor is a 10S20F design with a factory-installed clutch and comes prefilled with the correct lubricant to ease installation. Knowing the pulley size, groove count and oil type helps ensure you get the right replacement for your vehicle’s system.

• Compressor type: 10S20F

How should this unit be installed and what prep is required?

Proper system cleaning and correct charge are essential for long-term performance; installing a new compressor into a contaminated system risks early failure. ILONPA recommends professional installation and full evacuation, flushing, and recharge to OEM refrigerant and oil specifications.

• Completely clean the AC system (flush and remove moisture and debris)
• Replace receiver/drier or accumulator and expansion device where applicable
• Vacuum, leak test, and recharge to manufacturer refrigerant spec
• Professional commissioning recommended to verify clutch engagement and pressures

Will this compressor match my old part numbers and improve reliability?

ILONPA supplies compressors matching many OE references; check the cross-reference list and your old part number to confirm match. While a proper replacement restores AC function, longevity depends on system cleanliness and correct installation.

• Cross-references include CO 29002C, 1520410, 1520940 and other OE numbers
• Designed to meet OE mounting and pulley specifications
• Prefilled oil reduces handling steps during swap
