The 20731 part is part of this line, offering a molded radiator coolant hose solution that integrates an internal spring to maintain hose integrity under pressure variations.

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 provides a precise shape that fits securely between radiator and engine components, reducing the risk of leaks. Both ends have an inside diameter of 2.25 inches (57 mm), making it suitable for systems requiring consistent hose diameter. The internal spring reinforcement prevents hose collapse during engine vacuum conditions, maintaining coolant flow and system reliability. With a centerline length of 25.6 inches (650 mm), this hose is designed for specific routing paths in compatible vehicles.

Common Applications and Issues Addressed

• Replacement of worn or cracked radiator coolant hoses
• Prevention of hose collapse under vacuum conditions
• Maintaining proper coolant flow to avoid engine overheating
• Ensuring leak-free connections in molded hose applications
• Restoring original equipment fit and function in cooling systems

Installation Notes and Tips

Ensure the engine is cool before removing the old hose to prevent burns. Verify the inside diameter and length match your vehicle’s specifications. Use appropriate clamps to secure the hose ends firmly without over-tightening, which can damage the hose. Inspect surrounding components for wear or damage during installation. The molded shape requires proper alignment to avoid kinks or stress points.
