Common Problems This Part Can Address

• Cracked or leaking A/C liquid hose on the high-pressure side

• Poor A/C performance caused by a damaged liquid line
• Service issues on vehicles requiring a hose assembly without a switch port
• Replacement needs for factory air or R134a system configurations listed in fitment

Installation Notes and Tips

Verify the vehicle’s A/C layout before ordering, especially whether the system uses an orifice tube and whether the application is listed as w/o Orifice Tube. Confirm the refrigerant type, hose routing, and connection style against the original part on the vehicle. For best results, replace the liquid line only on the exact fitment listed for your Ford Explorer, Ford Ranger, Mazda Navajo, or related application.
