About the Gates Molded Coolant Hose Product Line

The Molded Coolant Hose line by Gates focuses on precision-molded hoses designed to meet specific vehicle requirements. These hoses are manufactured to maintain consistent coolant flow and resist deformation under pressure and temperature variations. The 21455 part number is part of this line, offering a molded, spring-reinforced solution that fits applications requiring a 2.5-inch diameter hose with a 16.6-inch length.

Detailed Product Description

This radiator coolant hose is made from EPDM, a synthetic rubber known for its excellent resistance to heat, ozone, and automotive fluids. The molded construction ensures the hose maintains its shape and fits securely between cooling system components. The internal spring reinforcement prevents hose collapse under vacuum or pressure fluctuations, maintaining optimal coolant flow. Both ends have an inside diameter of 2.5 inches (64 mm), making it suitable for vehicles requiring this size. With a centerline length of 16.6 inches (422 mm), the hose is designed for precise fitment without the need for modifications.

Common Applications and Issues Addressed

• Replacement of worn or cracked radiator coolant hoses
• Prevention of coolant leaks due to hose deformation or failure
• Maintaining proper coolant flow to avoid engine overheating
• Addressing hose collapse caused by vacuum pressure
• Ensuring compatibility with vehicles requiring molded 2.5-inch diameter hoses

Installation Notes and Tips

Before installation, verify the hose dimensions against your vehicle’s specifications to ensure compatibility. The molded design requires no additional shaping or cutting. Inspect hose clamps and surrounding components for wear and replace if necessary to ensure a secure seal. Properly route the hose to avoid contact with sharp edges or hot engine parts that could cause premature wear.
