$859.99

Keep cabin air moving with the Four Seasons A/C Compressor 158391, the heart of your vehicle's air-conditioning loop. It draws in low-pressure refrigerant vapor and compresses it to high pressure, circulating refrigerant through the condenser, expansion device, and evaporator so the system can pull heat from the cabin. It installs as a direct-fit replacement for the 2018-2020 Genesis G80.

  • Core A/C function: pressurizes and circulates refrigerant to drive the cooling cycle.
  • Direct-fit application: matched to the listed Genesis G80 years for a straightforward replacement.
  • Signs this part may need replacing: weak or no cold air, unusual noise from the compressor, or a clutch that won't engage — have the system diagnosed to confirm the compressor is the cause before replacing.

When servicing the A/C system, follow the vehicle service procedure for evacuating, charging, and the correct refrigerant oil type and quantity. Consult the service information for any required O-rings, seals, or related components not supplied with this unit.
