Detailed Fitment and Function

This A/C manifold hose assembly is a direct-fit style replacement for the suction and discharge lines used on 1987-1989 Chevrolet Astro and 1987-1989 GMC Safari models with front air conditioning only. The HA111937C helps restore proper refrigerant flow between the compressor and the rest of the HVAC system when the original hose assembly is worn, leaking, or damaged. Universal Air HA111937C is identified for these van applications and should be matched to vehicles that do not use rear A/C.

Common Problems This Part Can Address

• Refrigerant loss from cracked or deteriorated hose sections
• Leaks at aging hose connections or manifold points
• Reduced A/C performance caused by damaged suction or discharge routing
• Service issues after removal of a failed original hose assembly
• Front-system A/C repair on Chevrolet Astro and GMC Safari vans

Installation Notes and Tips

Verify that the vehicle is a 1987-1989 Chevrolet Astro or GMC Safari without rear A/C before ordering. Inspect mating seals, compressor ports, and adjacent HVAC components for wear or contamination before installation. Proper evacuation, leak checking, and recharge procedures are required after the hose assembly is installed. Part number HA111937C should be confirmed against the existing routing and connection style on the vehicle.

Quality Assurance

Universal Air identifies this part within its Suction and Discharge Assembly line for HVAC hose and pipe applications. Confirm fitment by year, make, model, and rear A/C configuration to ensure the correct replacement for the vehicle.
