Gates 20584 Radiator Coolant Hose - Lower or Upper

Gates 20584 Molded Coolant Hose Overview

The Gates 20584 molded coolant hose is an OE-style radiator coolant hose built for upper and lower cooling-system applications, plus heater and bypass routing where specified. Made from EPDM and formed to OEM-quality dimensions, it supports direct replacement on a wide range of classic Ford, Chevrolet, GMC, Pontiac, Mercury, and Oldsmobile applications.

Gates Molded Coolant Hose line is built for replacement work that calls for accurate shape, consistent fit, and broad application coverage. If you are replacing a radiator hose on a 1957-1961 Ford F-100, a 1963-1964 Chevrolet Impala, or a 1994-1995 Ford F-250, the Gates 20584 gives you a molded hose solution that matches the vehicle’s routing requirements.

Key Features

• EPDM construction for coolant-system durability
• Molded hose profile for proper routing and fit
• 1.75 in. inside diameter at both ends
• 24 in. centerline length
• No spring and no quick-connect fittings
• Direct replacement coverage for upper and lower radiator hose applications

Detailed Product Description

This radiator coolant hose is engineered for vehicles that need a formed hose rather than a universal straight section. The molded shape helps maintain the correct path through the engine bay, which is important on older vehicles where clearance around the radiator, water pump, and heater plumbing can be tight. The Gates 20584 part number is also referenced in interchange listings for several aftermarket and OE-style replacement numbers, making it a practical match when cross-referencing a cooling-system repair.

Common Problems This Hose Can Address

• Incorrect hose routing after a cooling-system repair
• Leaks at the upper or lower hose connection points
• Fitment issues caused by using a universal hose where a molded hose is required
• Cooling-system service on classic Ford, Chevrolet, GMC, Pontiac, Mercury, and Oldsmobile vehicles

Installation Notes and Tips

Verify hose routing, end diameters, and centerline length before installation. On applications noted as cut-to-fit, trim only as required for the specific vehicle configuration. Inspect clamps, radiator necks, heater fittings, and adjacent cooling components before reassembly to help prevent repeat leaks. Confirm the hose path clears belts, pulleys, and moving engine components after installation.
