Detailed Description

This rear AC line kit is built for Buick Enclave, Chevrolet Traverse, GMC Acadia, GMC Acadia Limited, and Saturn Outlook models with auxiliary inlet and outlet routing. Dorman 926-964 uses reinforced rubber instead of factory aluminum, helping reduce the installation difficulty often associated with rigid lines under the vehicle. The line is intended for high-pressure A/C service and includes gasket/seal components for the connection points. This part cross-references OE numbers 1533768 and 1534653 for the same application.

Common Repair Symptoms

• A/C loss caused by corroded rear refrigerant lines
• Visible cracking, pitting, or leakage in the original tubing
• Reduced cooling performance from refrigerant loss
• Failed rear auxiliary inlet/outlet line routing
• Service issues on underbody aluminum A/C lines

Installation Notes and Tips

Verify the vehicle’s rear auxiliary inlet and outlet configuration before ordering. Inspect the mating surfaces and replace worn seals during installation. Confirm line routing matches the original layout and check the system for leaks after evacuation and recharge. Because this is an underbody A/C line assembly, proper support and careful routing help prevent abrasion or kinking.

Quality Assurance

Dorman OE FIX parts are engineered as service-focused replacements for common OE failure points. This tubing is made to address corrosion-related line failures while maintaining the required A/C system function.
