Restoration Correct Original AC Delco Part Correct Fit And Finish Fits Inline 6 and V8 Engines Made In USA Is the ac compressor not working on your 1967-1981 Firebird? When the electromagnet inside the ac clutch assembly turns on, it produces a powerful magnetic field through the rotor. Since the fan belt rotor and the air conditioner rotor are both made out of iron, the magnetic field magnetises both of them, pulling them towards each other. This causes the friction plates to push tightly in to each other. Initially, the rotor friction plate is turning and the compressor friction plate is not. Once they are touching, however, friction between the two plates makes the air conditioner rotor spin. When the electromagnet is turned off, the friction plates spring apart and the compressor stops moving. Don't settle for just any replacement part, use AC Delco what came on your 1967, 1968, 1969, 1970, 1971, 1972, 1973, 1974, 1975, 1976, 1977, 1978, 1979, 1980, 1981 Firebird when it rolled off the assembly line.
