Dayco Radiator Coolant Hose P/N:71977
Dayco 70682 upper radiator coolant hose for the 1975-1976 Ford F-150 V8 5.9L or 6.4L and other vehicles carries coolant between the engine and the radiator. This Dayco coolant hose is a single I.D. hose.
Coolant leaks, a cracked, soft or swollen hose, or an engine that runs hot can mean the upper hose is worn. A thermostat, radiator cap or water pump can be behind the same signs, so find the cause before you buy. Inspect the hose only with the engine off and cool.
Fitment includes the 1975-1976 Ford F-150 V8 5.9L or 6.4L, the 1968-1976 Ford F-250 V8 5.9L or 6.4L and the 1968-1976 Ford F-100 V8 5.9L or 6.4L, and each of these trucks takes one hose. If your truck is a different Ford model, look up its year and engine in the "Vehicles it fits" section.
