Made from EPDM rubber and finished in black, it is shaped as a dual I.D. hose to match the connection sizes used in the vehicle’s cooling circuit.\u003c\/p\u003e\u003cp\u003eCompatible with 1985-1989 Ford Ranger, upper position, this hose is specified to SAE J20R4 Class D-1 and SAE J1684 Type EC standards. If you are replacing a worn upper radiator hose on a Ford Ranger, Part Number 71239 provides the correct curved profile and dual-diameter fitment for the listed application.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eEPDM construction for coolant-hose service\u003c\/li\u003e\n\u003cli\u003eBlack finish for OE-style appearance\u003c\/li\u003e\n\u003cli\u003eDual I.D. hose design\u003c\/li\u003e\n\u003cli\u003eEnd 1 inside diameter: 1 3\/16 in.\u003c\/li\u003e\n\u003cli\u003eEnd 2 inside diameter: 1 13\/32 in.\u003c\/li\u003e\n\u003cli\u003eTrunk height: 15 1\/2 in.\u003c\/li\u003e\n\u003cli\u003eMeets SAE J20R4 Class D-1 and SAE J1684 Type EC specifications\u003c\/li\u003e\n\u003cli\u003eFits upper radiator hose applications on select Ford Ranger models\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eProduct Details\u003c\/h2\u003e\u003cp\u003eDayco’s Curved Radiator Hose line is built for vehicle-specific cooling-system routing where a formed hose is required to maintain proper alignment and flow path. This Part Number 71239 hose is shaped for the upper radiator connection on 1985-1989 Ford Ranger models and uses a dual inside diameter design to match the different connection sizes at each end. The EPDM rubber construction is suited for coolant exposure and everyday engine-bay temperatures, while the curved profile helps replicate the original hose routing on the Ford Ranger.\u003c\/p\u003e\u003cp\u003eThis part cross-references Motorcraft KM1518 and Gates 21430 for the same application.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCracked or hardened upper radiator hose material\u003c\/li\u003e\n\u003cli\u003eCoolant leaks at the hose connection points\u003c\/li\u003e\n\u003cli\u003eImproper hose routing from a collapsed or misshaped hose\u003c\/li\u003e\n\u003cli\u003eCooling-system service on a Ford Ranger upper hose location\u003c\/li\u003e\n\u003cli\u003eReplacement of a worn dual-diameter radiator hose\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify the hose routing, end diameters, and upper-position application before installation.
