How It Works

This hose carries refrigerant on the discharge side of the A/C system, moving it from the compressor to the condenser before the refrigerant continues through the cooling circuit. On rear AC-equipped Chevrolet Tahoe, GMC Yukon, GMC Yukon XL, Chevrolet Suburban, and Cadillac Escalade models, correct hose routing is important for maintaining system performance and proper rear cabin cooling.

Common Problems It Can Address

• Refrigerant loss from a cracked or leaking discharge hose
• Poor rear cabin cooling on rear AC-equipped GM SUVs
• Compressor discharge line damage from age, vibration, or heat exposure
• A/C system service needs after hose corrosion or seal failure
• Incorrect hose routing when replacing a worn high-side line

Installation Notes

Verify the vehicle’s rear AC configuration, model year, and any listed codes before ordering. Compare the original hose routing, connection points, and condenser/compressor interfaces to confirm the correct application for your Chevrolet Tahoe, GMC Yukon, or Cadillac Escalade. Recover refrigerant properly and inspect related seals, O-rings, and mating components during service.
