The curved profile helps match the factory hose path, while the dual inside diameters support the different connection sizes required by the listed vehicles. The hose is made from EPDM and built to SAE J20R4 Class D-1 and SAE J1684 Type EC standards. This part cross-references Motorcraft KM1055 and Gates 21045 for the same application. Dayco 70978 is a practical replacement choice when servicing the cooling system on classic Ford truck platforms.\u003c\/p\u003e\u003ch2\u003eCommon Uses\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacing a cracked or aged upper radiator hose\u003c\/li\u003e\n\u003cli\u003eRestoring coolant flow through the cooling system\u003c\/li\u003e\n\u003cli\u003eAddressing leaks at hose connections\u003c\/li\u003e\n\u003cli\u003eReplacing a hose with incorrect end diameters\u003c\/li\u003e\n\u003cli\u003eServicing a curved upper hose route on classic Ford trucks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\u003cp\u003eVerify the hose routing and end diameters before installation.
