This design ensures a secure fit and proper coolant flow in vehicles requiring non-linear hose routing. The 71280 part number exemplifies this with its dual i.d. hose construction and protective sleeve, tailored for select Ford and Mazda models.\u003c\/p\u003e\u003ch2\u003eTechnical Description and Features\u003c\/h2\u003e\u003cp\u003eThis radiator coolant hose is made from EPDM, a synthetic rubber known for its resistance to heat, ozone, and coolant chemicals, making it suitable for under-hood applications. The hose features a dual inside diameter design, measuring 1 7\/16\" on one end and 1 1\/2\" on the other, allowing it to connect different sized fittings securely. The black hose includes a protective sleeve to guard against abrasion, although it does not contain a heat shield. It meets SAE J20R4 Class D-1 and SAE J1684 Type EC standards, ensuring compliance with industry coolant hose requirements. The trunk height of 12 3\/4\" supports proper routing and fitment in the engine bay.\u003c\/p\u003e\u003ch2\u003eCommon Applications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement of worn or cracked radiator coolant hoses in Ford B4000 and Bronco II\u003c\/li\u003e\n\u003cli\u003eAddressing coolant leaks caused by hose degradation in Mazda Navajo and Ranger\u003c\/li\u003e\n\u003cli\u003eResolving improper fitment issues due to varying inlet sizes with dual i.d. hose design\u003c\/li\u003e\n\u003cli\u003ePreventing abrasion damage with the included protective sleeve\u003c\/li\u003e\n\u003cli\u003eMaintaining coolant system integrity in Ford Explorer models\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the engine is cool before removing the old radiator hose to avoid burns. Verify the hose ends match the radiator and engine inlet diameters (1 7\/16\" and 1 1\/2\") for proper fit. Use appropriate clamps to secure the hose and check for leaks after installation. The protective sleeve should be positioned to face areas prone to abrasion. Inspect surrounding components for wear during replacement to maintain system reliability.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eDayco radiator hoses are manufactured to meet SAE specifications, providing consistent quality and performance.
