What It Helps Address

• Corrosion or wear in the HVAC line assembly
• Loss of cooling performance caused by a failed liquid line
• Service replacement needs on GM trucks and SUVs with listed fitment

Installation Notes

Confirm year, make, model, and HVAC configuration before installation. Several listings exclude rear A/C, and some applications note auxiliary A/C or a required companion part number. Match the vehicle exactly to the fitment notes for Chevrolet Silverado, GMC Sierra, Cadillac Escalade, and related models. Part number HA111368C should be checked against the original line routing and system layout before service.
