Description
A-6 A/C Compressor — Aluminum Replacement, 1-Groove, 12V
A complete A-6 compressor assembly with the clutch already fitted — a lightweight aluminum replacement for the classic GM / Frigidaire A-6. Single V-groove pulley (130 mm / ~5″), 12V clutch, 2 o’clock clocking, metric fittings and a high-pressure switch.
The heart of the A/C system
The compressor pressurizes and circulates refrigerant through the A/C system — without it, there’s no cooling. This is the complete A-6 assembly, clutch included, in a lightweight aluminum body.
When the original compressor is noisy, seized, or won’t engage, replacing it with a fresh unit is the core of an A/C repair. Because debris from a failed compressor spreads through the system, a proper install includes flushing and replacing the drier and metering device.

Technical specs
Installing a new compressor? Flush the system, replace the receiver-drier or accumulator and the expansion / orifice device, and follow the correct oil charge before you evacuate and recharge. Skipping these steps is the most common cause of a repeat failure.
