Key Features

• EPDM rubber construction for coolant-system service
• Molded design for accurate hose routing
• 1.25 in. inside diameter at both ends
• 13.3 in. centerline length
• No spring and no quick-connect fittings

Product Details

This Gates Molded Coolant Hose line is engineered as a direct replacement option for a wide range of radiator and HVAC coolant routing needs. Part number 21025 is shaped for applications that require a formed hose rather than a straight universal length, helping maintain factory-style routing in vehicles including Toyota Camry, Toyota Corolla, and Nissan Pathfinder. This part cross-references Dayco 70815 and Continental 60932 for the same application.

What It Helps Solve

• Cracked or leaking radiator coolant hose
• Collapsed or softened hose sections from age and heat
• Incorrect hose routing after cooling-system repair
• Loss of coolant from worn upper or lower hose connections
• Service delays when replacing molded OE-style hoses

Installation Notes and Tips

Verify hose routing, end diameters, and centerline length before installation. This molded hose is listed for upper, lower, upper driver-side, and lower pipe-to-radiator positions across the cataloged applications. Confirm the vehicle-specific position and trim details for 1970-1995 coverage, including Fits 1995 Nissan Pathfinder, Upper; Fits 1988-1991 Toyota Camry, Lower; and Fits 1989-1994 Mitsubishi Montero, Upper. Use proper coolant service procedures and inspect adjoining clamps, necks, and pipes for wear before reassembly.
