Details on the Curved Radiator Hose Product Line

The Dayco Curved Radiator Hose line focuses on delivering hoses with precise bends and consistent diameters to ensure optimal coolant flow and fitment in various cooling system configurations. The 71812 part number exemplifies this line by offering a single inside diameter hose made from EPDM, meeting industry SAE standards for durability and performance in automotive cooling applications.

Technical Description and Specifications

This radiator coolant hose is manufactured from EPDM, a synthetic rubber known for its resistance to heat, ozone, and coolant chemicals, making it suitable for long-term use in engine cooling systems. Both ends of the hose have an inside diameter of 2 1/2 inches, ensuring a consistent connection to radiator and engine fittings. The hose type is a single inside diameter design, which simplifies installation and compatibility with matching components. It complies with SAE J20R4 Class D-1 and SAE J1684 Type EC standards, confirming its suitability for automotive coolant applications. The hose does not include additional protective features such as heat shields or sleeves, so proper routing away from extreme heat sources is recommended.

Common Applications and Problem Solving

• Replacement of worn or cracked radiator coolant hoses in compatible vehicles
• Resolving coolant leaks caused by hose degradation or damage
• Maintaining proper coolant flow to prevent engine overheating
• Addressing fitment issues requiring a curved hose with 2 1/2 inch diameter ends
• Upgrading OEM hoses with a durable EPDM material hose meeting SAE standards

Installation Notes and Tips

Ensure the hose is routed away from sharp edges and high heat sources since this hose does not include a heat shield or protective sleeve. Verify that the 2 1/2 inch inside diameter matches the radiator and engine fittings before installation. Use appropriate clamps to secure the hose ends and check for leaks after installation. It is recommended to inspect adjacent components for wear during replacement to maintain system integrity.
