Four Seasons A/C Compressor P/N:178348
Four Seasons 57240 A/C compressor for the 1989-1991 Chevrolet C1500 and other vehicles compresses refrigerant and moves it through the air conditioning system. This remanufactured Four Seasons ac compressor is the GM R4 type.
Warm air from the vents or a noisy compressor with the A/C on can point to a worn compressor. These signs alone do not prove it is the problem, since a refrigerant leak is another common cause.
It fits vehicles including the 1989-1991 Chevrolet C1500 and the 1987-1991 Chevrolet Suburban, and it is an ac compressor for the 1989-1991 Chevy K1500, with one compressor per vehicle. To see whether your own year and model is covered, look it up in the "Vehicles it fits" section.
