What It Helps Fix

• Loss of A/C compressor performance in Jeep Cherokee, Comanche, or Wagoneer systems
• Noise or rough operation from a worn SD508 compressor
• Reduced cooling output in factory air HVAC systems
• Service needs tied to compressor replacement on older Jeep A/C systems
• System issues addressed during compressor-related A/C repair work

Installation Notes

Verify the vehicle uses a factory air setup with the SD508 compressor before ordering. Match the application details in the fitment list, including the listed compressor, filter drier, expansion valve, flush, and oil references for the correct Jeep Cherokee, Comanche, or Wagoneer configuration. Part number 3143N should be confirmed against the existing A/C system before installation.
