Detailed product description

Gates 25255 is a radiator coolant hose engineered to replicate the shape and routing of many OE coolant hoses without requiring a molded replacement. Its flexible design makes it easier to service vehicles with complex hose paths, including upper radiator hose and lower radiator hose locations.

Additional coverage includes many Toyota Camry, Mazda 626, and Oldsmobile Cutlass applications across the listed years.

What this hose helps address

• Cracked or hardened coolant hoses
• Leaking upper or lower radiator hose connections
• Routing problems when a formed hose is no longer available
