What It Helps Address

• Refrigerant loss from a cracked or leaking discharge hose
• Reduced A/C performance caused by restricted hose flow
• Damaged hose ends or deteriorated seals at the connection points
• Service issues on discharge line routing in the A/C system

Installation Notes

Verify the vehicle uses R134A refrigerant and matches the listed discharge line configuration before installation. Inspect mating surfaces and adjacent A/C components for wear or contamination, and replace any damaged seals or connections as needed. Evacuate and recharge the system according to proper A/C service procedures after installation.
