About the Molded Coolant Hose Product Line

The Molded Coolant Hose line by Gates focuses on delivering hoses that are pre-formed to match specific vehicle cooling system layouts. This eliminates the need for bending or shaping during installation, reducing the risk of leaks or hose damage. The 20406 part benefits from this design approach, providing a direct replacement hose that fits Chevrolet and Ford truck models accurately.

Detailed Product Description

This radiator coolant hose is made from EPDM, a synthetic rubber known for its resistance to heat, ozone, and coolant chemicals, which helps maintain hose integrity over time. The molded construction ensures the hose maintains its shape and fits precisely between cooling system components. With a centerline length of 22 inches (559 mm) and an inside diameter of 1.5 inches (38 mm) on both ends, the hose is tailored for the cooling systems of Chevrolet C10 Suburban, C20 Suburban, Ford F-250, and F-350 trucks. The absence of springs and quick connect fittings means fewer potential failure points and easier inspection during routine maintenance.

Common Applications and Problem Solving

• Replacement of worn or cracked radiator coolant hoses in Chevrolet and Ford trucks
• Resolving coolant leaks caused by hose degradation or improper fit

• Addressing hose collapse or deformation under pressure
• Ensuring compatibility with factory cooling system configurations

Installation Notes and Tips

Before installation, verify the hose length and diameter match the original part. The molded shape should align with the vehicle’s cooling system layout without forcing or bending. Use appropriate clamps to secure the hose ends and check for leaks after installation. It is recommended to inspect adjacent cooling system components for wear or damage during replacement.
