A-Premium AC Compressor 10S20F Direct-Fit for GM Trucks & SUVs — Prefilled PAG46, 4-Groove Pulley, Clutch

The A-Premium Air Conditioner AC Compressor with Clutch is a direct-fit replacement 10S20F compressor prefilled with PAG46 oil and a clutch assembly for select Chevrolet, GMC and Cadillac trucks and SUVs.

This heavy-duty replacement compressor is engineered to restore air conditioning performance in compatible GM vehicles without the expense of an aftermarket remanufacture. It arrives prefilled with approximately 170 ml of PAG46 oil (±20 ml tolerance), includes a 4-groove pulley and the clutch assembly, and is built to match OE mounting and connector arrangements — but confirm the A/C line connector and the two-mounting-hole pattern before ordering to ensure proper fitment.

Which vehicles will this A-Premium compressor fit?

This compressor is designed for many Chevrolet, GMC and Cadillac models from the 2000–2019 era, primarily full-size trucks and SUVs. Fitment covers Silverado, Sierra, Tahoe, Suburban, Yukon, Avalanche, Express vans, Escalade and related HD variants — typically models without rear AC, or with specific engine displacements listed.

• Chevrolet Silverado 1500/2500/3500 (model years 2000–2002 / select HD years)
• GMC Sierra 1500/2500/3500 and Yukon/Yukon XL (2000–2002 range)
• Chevrolet Tahoe/Suburban, Avalanche, Express vans (select years and engines)
• Cadillac Escalade and Escalade EXT (2002 models without rear AC)

How do the technical specs affect installation and compatibility?

Key specifications determine whether the unit will integrate cleanly with your vehicle’s existing system. The 10S20F compressor type and 4-groove pulley match many original equipment designs, while the included clutch simplifies installation compared to buying separate components.

• Compressor type: 10S20F — matches many GM OE units for direct fit.
• Oil type/prefill: PAG46 with ~170 ml, avoids initial oil top-up in most swaps.
• Pulley grooves: 4 — ensure belt alignment with your vehicle’s serpentine setup.
• Mounting: 2 mounting holes — verify your vehicle uses 2-hole pattern (not 1).

What should I check before purchasing to avoid returns?

Confirming the small details prevents mismatches: compare the vehicle list and reference numbers, inspect your current compressor’s mounting holes and A/C line connector, and verify pulley groove count. Reference numbers and OEM cross-refs help ensure you select the correct replacement part.

• Compare listed reference numbers (e.g., CO29002C, 77362, GG362, 15036042) with the old unit.
• Verify your vehicle’s engine size and whether rear AC is present or absent.
• Inspect the existing compressor for 2 mounting holes and a 4-groove pulley.
• Check the A/C line connector type to match the new compressor’s inlet/outlet.

What comes in the box and what tools or steps are required?

The package includes the compressor assembly complete with clutch and prefilled oil. Installation typically requires standard garage tools, system evacuation and recharge equipment, and adherence to safety and refrigerant handling practices.

• Included: A-Premium 10S20F compressor, clutch assembly, prefilled PAG46 oil.
• Tools: socket set, torque wrench, belt tool, manifold gauge set, vacuum pump for evacuation.
• Service steps: remove old unit, compare fittings, mount new compressor, torque to spec, evacuate system and recharge to manufacturer refrigerant weight.

Who is this for: This A-Premium compressor is intended for DIY mechanics, independent shops and fleet managers who need a reliable, direct-fit replacement for compatible GM full-size trucks, vans and SUVs. It’s best for owners who can verify fitment details and have access to proper AC service equipment or a qualified technician to complete evacuation and recharge procedures.
