Made from EPDM (ethylene propylene diene monomer) rubber, this hose offers excellent resistance to heat, ozone, and coolant chemicals, which helps maintain system integrity under demanding conditions. Both ends of the hose have an inside diameter of 1 9\/16 inches, providing a consistent fit for the radiator connections. The hose complies with SAE J20R4 Class D-1 and SAE J1684 Type EC standards, ensuring it meets industry requirements for coolant hoses. The curved design and 9-inch trunk height allow for proper routing within the engine bay without kinking or restricting coolant flow.\u003c\/p\u003e\u003ch2\u003eApplications and Common Issues Addressed\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement of worn or cracked radiator coolant hoses on Jaguar Vanden Plas, XJ6, and XJS\u003c\/li\u003e\n\u003cli\u003ePrevention of coolant leaks caused by hose degradation or swelling\u003c\/li\u003e\n\u003cli\u003eRestoration of proper coolant flow to avoid engine overheating\u003c\/li\u003e\n\u003cli\u003eAddressing hose collapse or blockage due to age or heat exposure\u003c\/li\u003e\n\u003cli\u003eMaintaining cooling system pressure and efficiency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eWhen installing the Dayco Curved Radiator Hose 71666, ensure the hose is routed without sharp bends or twists to maintain coolant flow. Verify that the inside diameters match the radiator and engine fittings for a secure connection. Use appropriate clamps to secure the hose ends, and inspect the cooling system for any additional wear or damage during replacement. Since this hose does not include a heat shield or protective sleeve, take care to avoid contact with high-temperature components that could accelerate wear.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eDayco manufactures the Curved Radiator Hose 71666 to meet SAE specifications, providing assurance of material quality and dimensional accuracy.
