Gates 25582 Radiator Coolant Hose - Lower or Upper

Flexible Lower Radiator Hose for Classic Ford and Mercury

The Gates 25582 Flexible Coolant Hose is a standard radiator coolant hose built for lower hose applications where a formed hose is difficult to source. Its flexible construction helps it follow the needed bends and angles on a range of classic Ford, Lincoln, and Mercury vehicles, making it a practical OE-style replacement for aging cooling system plumbing.

Gates Flexible Coolant Hose (Standard) is part of the Vulco-Flex II line, which focuses on adaptable coolant routing and a sealing surface engineered for improved leak resistance. For restorations and maintenance on vehicles such as the Ford LTD, Mercury Marquis, and Lincoln Continental, the 25582 offers a straightforward way to replace a worn lower radiator hose without relying on a hard-to-find molded shape.

Detailed Description

The Gates 25582 radiator coolant hose is engineered for lower cooling system routing where flexibility matters. Built from EPDM with steel reinforcement, it is intended to replicate the angles and planes of many OE coolant hoses while reducing the cost and delay of sourcing a vehicle-specific molded hose. This makes it a strong choice for classic applications that need a dependable lower hose solution, including Ford LTD, Mercury Marquis, and Lincoln Continental models.

This part cross-references Gates 25582 and Monroe Shocks & Struts (e.g., 31650, FF260) for the same application.

What It Helps Solve

• Cracked or deteriorated lower radiator hose material
• Cooling system leaks at the hose sealing surface
• Difficulty sourcing an exact molded OE hose shape
• Improper hose routing on classic Ford, Lincoln, and Mercury vehicles
• Replacement needs for aging coolant hose assemblies
