Product Details

Global Parts 4811284 is built for air conditioning system service where the hose assembly must carry refrigerant through the correct circuit path. The manufacturer identifies suction hoses as the low-side line from the compressor to the evaporator, discharge hoses as the high-side line from the compressor to the condenser, liquid lines as the condenser-to-evaporator connection, and manifold hoses as combined suction and discharge assemblies. This part number is listed for Buick LeSabre, Oldsmobile 98, Oldsmobile Delta 88, and Pontiac Bonneville applications shown above.

Common Repair Uses

• Refrigerant line leakage at the hose assembly
• Cracked or deteriorated A/C hose material
• Loss of system pressure from a damaged line connection
• Poor A/C performance caused by restricted or failing hose routing
• Service replacement for aging Buick LeSabre, Oldsmobile Delta 88, or Pontiac Bonneville A/C plumbing

Installation Notes

Verify the hose routing, port locations, and connection style against the original part before installation. Confirm the vehicle application by year, make, and model, and inspect adjacent seals, fittings, and system components for wear before reassembly. Proper evacuation and recharge procedures should be followed after A/C line replacement.
