Details on the Curved Radiator Hose Product Line

The Dayco Curved Radiator Hose line focuses on providing hoses with precise bends and dual inside diameters to accommodate specific radiator and engine connections. This product line is engineered to maintain coolant flow integrity while fitting tightly in confined engine compartments, reducing the risk of leaks and premature wear. The 71712 part exemplifies this with its tailored dimensions and material compliance to SAE standards.

Product Description and Specifications

This radiator coolant hose features a curved design with a trunk height of 31, allowing it to fit seamlessly within the cooling system of compatible vehicles. The hose is made from EPDM, a synthetic rubber known for its resistance to heat, ozone, and coolant chemicals, ensuring long service life. The dual inside diameter ends—1 1/4 inch and 1 1/2 inch—allow for a secure connection between different sized fittings, reducing the need for adapters. The hose does not include a heat shield or protective sleeve, which is typical for this application and vehicle fitment.

Common Applications and Problem Solving

• Replacement of worn or cracked radiator coolant hoses in Chrysler Caravan and Dodge Grand Caravan models
• Addressing coolant leaks caused by hose degradation in Plymouth Voyager and Town & Country vehicles
• Restoring proper coolant flow and preventing overheating in Grand Voyager engines
• Ensuring a secure fit where radiator hose diameters differ between engine and radiator connections
• Maintaining cooling system integrity in vehicles requiring SAE J20R4 Class D-1 compliant hoses

Installation Notes and Tips

• Verify hose dimensions and fitment with your vehicle’s make and model before installation
• Ensure all clamps are properly tightened to prevent leaks but avoid over-tightening which can damage the hose
