Installation Notes

Verify compressor style and system configuration before installation. This kit is listed for 1997-1999 Jeep Cherokee and 2000-2001 Jeep Cherokee applications with the SD709 compressor. For 2000-2001 models, confirm the drier with block fittings requirement shown in the fitment notes. Always evacuate and recharge the system according to the vehicle service procedure and refrigerant specifications.
