• Molded shape for factory-style hose routing

Detailed Product Description

Gates 20823 is a molded radiator coolant hose with a 1.5-inch inside diameter at each end and a 26.6-inch centerline length. The EPDM material is commonly used in cooling-system service because it handles heat and coolant exposure well, while the molded profile supports the original hose path under the hood. This makes the Gates 20823 a practical replacement for upper coolant and heater hose routing on vehicles including the 1998 Ford Explorer, 1995-1997 Ford Ranger, and 1995-1997 Mazda B4000.

Fitment also extends to classic applications such as the 1973-1979 Pontiac Grand Am, Grand Prix, LeMans, Firebird, Grand LeMans, Bonneville, Catalina, Laurentian, Parisienne, and GTO, plus the 1981 Toyota Land Cruiser and 1979 Buick Century and Regal. This part cross-references Dayco 70742 for the same application.

Common Problems This Hose Can Address

• Cracked or split upper radiator hose
• Coolant leaks at a worn molded hose section
• Collapsed or softened hose from age and heat
• Poor hose routing after a previous repair
• Cooling-system service on a vehicle with an OE-shaped hose path

Installation Notes and Tips

Confirm hose routing, end diameters, and centerline length before installation. Compare the original hose shape to the Gates 20823 to verify upper-position fitment, especially on 1995-1997 Ford Explorer and Ranger applications noted as optional or cut-to-fit in the fitment data. Inspect clamps, necks, and adjoining coolant components for wear before reassembly.
