Part number 71771 matches the listed fitment and uses EPDM material to handle coolant exposure in a standard radiator hose application. The curved shape helps follow the original hose path, while the equal-diameter ends support a consistent connection at both ends. If you are replacing a worn or cracked upper hose on these vehicles, 71771 provides a fitment-specific solution. This part cross-references Ford (e.g., F5AE-8B274-AC, F5AZ-8260-A) for the same application.\u003c\/p\u003e\u003ch2\u003eWhat It Is Used For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacing a cracked or deteriorated upper radiator hose.\u003c\/li\u003e\n\u003cli\u003eRestoring coolant flow between engine and radiator connections.\u003c\/li\u003e\n\u003cli\u003eAddressing leaks caused by hardened or swollen hose material.\u003c\/li\u003e\n\u003cli\u003eCorrecting hose routing issues on the original cooling layout.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify the hose path, end diameters, and upper position before installation.
