Detailed Description
This Dayco radiator coolant hose is a formed, curved hose intended for vehicles that require a specific bend to route coolant between engine and radiator connections. The EPDM rubber construction is selected for standard cooling-system temperatures and coolant exposure, while the protective sleeve adds an extra layer where routing passes near nearby components. If you are replacing a worn hose on a 2004-2008 Acura TSX upper radiator hose application, a 2006-2011 Hyundai Azera lower radiator hose application, or a 1991-1999 Mitsubishi 3000GT upper radiator hose application, the Dayco 71610 provides the correct curved profile for those listed positions.
This part cross-references Duralast D71610 and Gates 21737 for the same application.
