• Low refrigerant circulation in the HVAC system
• Compressor replacement on older R4-equipped vehicles

Installation Notes and Tips

Verify the compressor style, coil position, pulley diameter, and any notes such as old style, OE style, fixed orifice tube, or without rear A/C before ordering. Match the vehicle year, make, and model exactly to the fitment list, since several applications differ by configuration. For best results, compare the existing compressor and system layout to the catalog notes before installation.
