Four Seasons A/C Compressor P/N:58390
Four Seasons 57978 A/C compressor for the 1992-1993 Chevrolet S10 and other vehicles circulates refrigerant through the air conditioning system. This remanufactured GM V5 compressor includes its clutch.
Weak cooling, a noisy compressor or a clutch that does not engage can be signs the compressor is wearing out. These signs alone do not prove the compressor is at fault, though, because a refrigerant leak elsewhere in the system is another common cause. Only one compressor goes on the engine.
It is an ac compressor for the 1992-1993 Chevrolet S10 and the 1992-1993 GMC Sonoma.
