Dorman - HELP A/C Compressor Bypass Pulley P/N:34275
Dorman 34197 A/C compressor by-pass pulley for the 1990-1997 Chevrolet Lumina and other vehicles lets the original drive belt keep running after a failed A/C compressor is removed. It mounts where the compressor was and keeps the belt turning the engine's other belt-driven parts.
A failing compressor can show up as warm air from the vents or noise from the compressor. A low refrigerant charge, a worn clutch coil or a blown fuse can be behind a warm-air complaint too, so find the cause before buying. With this pulley fitted, the A/C stays off.
It fits the 1990-1997 Chevrolet Lumina, the 1995-1997 Chevrolet Monte Carlo and the 1997 Chevrolet S10, plus more vehicles. Open the "Vehicles it fits" section to check your exact model and engine.
