Marsflex AC Compressor with Clutch for Chevy Silverado 2000–2019 — Direct-Fit 10S20FC, Prefilled Oil

Marsflex AC Compressor with integrated clutch is a direct-fit replacement designed to restore air conditioning performance on compatible Chevrolet, GMC and Cadillac trucks from 2000–2019.

If your truck’s A/C has lost pressure, clutches slip, or the compressor has failed, this Marsflex unit offers a factory-style swap with prefilled oil and a mounted clutch. Engineered to match the 10S20FC compressor footprint, it arrives pre-lubricated and ready for installation into the models listed below — minimizing downtime when you need cabin cooling back fast. Before ordering, confirm the OE part number and the compressor appearance on your vehicle; this model has two mounting holes and will not fit applications that require a three-hole mount.

Will this compressor fit my Silverado or Sierra?

Compatibility covers specific years and engine sizes across Chevrolet Silverado/Sierra, Express/GMC Savana, and select Cadillac Escalade models. Use the OE numbers and visual checks to verify fitment because mounting configurations differ between model years and trims.

• Includes Chevy Express and GMC Savana vans from 2003–2019 where specified.

What are the key technical specifications I should know?

This compressor is built around the 10S20FC design and ships precharged with PAG oil formulated for R134a/R1234yf systems. The pulley and clutch match common GM belt drives for the covered years, and the unit comes with necessary seals to help simplify installation.

• Compressor type: 10S20FC with included clutch.
• Pulley diameter: 109 mm with 4-groove pulley.
• Oil: prefilled 160 + 10 ml PAG (R1234yf)46; refrigerant: R134a/R1234yf.
• Ships with gloves, O-rings, and a user manual; do not add extra oil to the precharged unit.

How should this be installed and what precautions are required?

Professional installation is strongly recommended to avoid damage from incorrect handling, to ensure correct refrigerant service procedures, and to verify electrical connections and mounting alignment. Inspect the compressor’s plug/pin and mounting hole count before fitting.

• Verify the compressor appearance, electrical connector, and OE part number against your vehicle before purchasing.
• Only use trained technicians to evacuate, charge, and test the A/C system after installation.
• Note: this compressor has two mounting holes — not suitable for vehicles requiring a different mount.
• Follow the included manual and product page warnings to prevent premature failure.
