Keep coolant flowing through your Ford heavy truck's cooling system with the Dayco Radiator Coolant Hose 71509. This is the lower radiator hose, and it drops in as a direct-fit replacement across a wide span of Ford 9000-series heavy-duty trucks — including the 1987-1994 FORD LS9000, the 1989-1994 FORD L9000, the 1988-1992 FORD LTL9000, the 1990-1994 FORD LTS9000, and many more. See the Buyer's Guide tab for the full list of covered applications and year ranges.
A radiator hose is a routine wear item: heat, pressure, and age cause the rubber to harden, crack, swell, or seep at the clamps. If a deteriorated lower hose is behind a coolant leak or overheating, replacing it with the 71509 restores a sound path for coolant flow.
