Four Seasons A/C Compressor P/N:157273
Four Seasons 58951 A/C compressor for the 1993 Cadillac Allante pumps refrigerant through the air conditioning system. This new Four Seasons AC compressor is a GM HD6 unit built to OE-level specifications.
Warm air from the vents, grinding or squealing from the compressor, or oil residue around its fittings can mean the compressor is wearing out. These signs alone do not prove the compressor is the problem, since a low refrigerant charge can cause weak cooling too.
This is a direct-fit AC compressor for the 1993 Cadillac Allante, which takes one.
