Detailed Description

Gates 25490 is part of the Flexible Coolant Hose (Standard) line, a product family focused on replacing difficult OE coolant hose shapes with a flexible format that simplifies service. The Vulco-Flex II design uses EPDM with steel reinforcement to maintain form while allowing the hose to route around engine bay obstacles. It is a direct-fit style solution for applications such as 1991-1997 Toyota Previa lower pipe-to-radiator routing, 1986 Plymouth Reliant upper, and multiple Chrysler, Dodge, Buick, Cadillac, Pontiac, Chevrolet, and Oldsmobile upper or lower hose positions.

This part cross-references FF320 and Walker Exhaust 31642 for the same application. Gates 25490 is a practical choice when you need a radiator coolant hose that can follow OE-style bends without relying on a molded shape.

Common Problems This Hose Can Address

• Cracked or leaking radiator coolant hose
• Hard-to-source molded hose replacement
• Incorrect hose routing on older cooling systems
• Leak points caused by poor sealing at the hose ends
• Service delays from unavailable OE hose shapes

Installation Notes and Tips

Verify end diameters, centerline length, and routing before installation. This hose is non-molded, so it should be positioned to match the vehicle’s original coolant path without kinks, twists, or sharp bends. Confirm the application position listed for your vehicle, such as upper or lower, before ordering. For fitment examples, this part fits 1991-1997 Toyota Previa, lower pipe to radiator; 1986 Plymouth Reliant, upper; and 1984 Chrysler Daytona, lower.
