Gates 25528 Radiator Coolant Hose

Flexible coolant hose for OE-style replacement

The Gates 25528 Flexible Coolant Hose is a radiator coolant hose built for applications that need a formed-style replacement without the cost of a molded OE hose. Its flexible construction bends in almost any direction, helping it follow the routing used on many classic Ford, Chevrolet, Dodge, Jeep, and Chrysler cooling systems.

Gates Vulco-Flex II hose design focuses on a better sealing surface for improved leak resistance, making it a practical choice for lower and upper radiator hose service where fit and routing matter.

Key features

• Flexible radiator coolant hose for direct cooling-system replacement
• EPDM and steel construction for durability in engine-bay heat
• Improved sealing surface for stronger leak resistance
• Replicates angles and planes of many OE coolant hose layouts
• Centerline length: 16.5 in. (419 mm)
• End 1 inside diameter: 1.5 in. (38 mm)
• End 2 inside diameter: 1.75 in. (44 mm)
• Non-molded design for routing flexibility

Detailed description

Part number 25528 is part of the Gates Flexible Coolant Hose (Standard) line, a product line focused on replacing hard-to-source OE coolant hose shapes with a hose that can be formed to the required path. This makes it a strong option for service work on vehicles such as the Ford Thunderbird, Chevrolet Camaro, and Jeep Cherokee when the original hose routing is no longer practical to source as a molded part. The Gates 25528 hose is designed to handle common lower and upper radiator hose applications while maintaining a secure seal at the connection points.

This part cross-references Continental 52418 and Standard Ignition FH60 for the same application.

What this hose helps address

• Cracked or aged radiator coolant hose material
• Leak points caused by poor sealing at the hose ends
• Hard-to-find OE hose shapes on older vehicles
• Cooling-system routing issues where a molded hose is unavailable
• Service replacement on lower or upper radiator hose locations

Installation notes and tips

Verify end diameters, centerline length, and routing before installation. This hose is not molded, so it should be positioned to match the vehicle’s original coolant path without kinks or sharp bends. Confirm whether the application is lower or upper hose service and check vehicle notes such as air conditioning, standard cooling, or thermostat spout configuration where listed in fitment.
