Details on the Curved Radiator Hose Product Line

The Dayco Curved Radiator Hose product line focuses on providing hoses with precise bends and dual inside diameters to ensure proper fitment and optimal coolant flow in specific vehicle applications. The 70998 part number is part of this line, engineered to meet SAE standards for coolant hoses, making it suitable for Ford Econoline models requiring a reliable curved hose solution.

Product Description and Specifications

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 dual inside diameter design (1 3/4 inches on one end and 2 inches on the other) allows for a secure fit on varying radiator and engine connections. The hose does not include a heat shield or protective sleeve, so it is intended for applications where additional protection is not required. Compliance with SAE J20R4 Class D-1 and SAE J1684 Type EC standards ensures the hose meets industry requirements for coolant system performance.

Common Applications and Issues Addressed

  • Replacement of worn or cracked radiator coolant hoses on Ford E-250 Econoline Club Wagon and E-350 Econoline models
  • Resolving coolant leaks caused by hose degradation or improper fit
  • Addressing overheating issues related to compromised coolant flow
  • Upgrading to a hose that meets SAE specifications for improved reliability
  • Ensuring proper coolant system pressure and flow with a dual inside diameter hose

Installation Notes and Tips

Before installation, verify the hose dimensions and fitment with your specific Ford Econoline model. Ensure the cooling system is cool and depressurized to avoid injury. Use appropriate clamps to secure the hose ends firmly to prevent leaks. Inspect adjacent components for wear or damage during replacement. Since this hose does not include a heat shield or protective sleeve, consider routing it away from high-heat sources or adding external protection if necessary.
