2001 Chevrolet Lumina V6-3.1L VIN JSECTION Compressor
The A/C compressor is driven by a belt from the engine crankshaft through the compressor clutch pulley. The compressor pulley rotates freely, without turning the compressor shaft, until an electromagnetic clutch coil is energized. When voltage is applied to energize the clutch coil, a clutch plate and hub is drawn toward the pulley. The magnetic force locks the clutch plate and pulley together as one unit to drive the compressor shaft.
