• Cracked, worn, or deteriorated rubber hose sections
• Corrosion or damage at the aluminum line connections
• Improper A/C system operation caused by a failed refrigerant hose assembly

Installation Notes and Tips

Verify the vehicle uses an R134-A A/C system and confirm the hose routing, fitting style, and manifold layout before installation. Replace the line only after recovering refrigerant and inspecting mating surfaces for damage or contamination. Use the included seals and O-rings during assembly, and check for leaks after evacuation and recharge.
