A hose that bulges, cracks, feels soft or weeps coolant, or a temperature gauge that climbs, can mean the hose is wearing out. Look it over only when the engine is cool. These signs alone do not prove the hose is the problem; a weak radiator cap can also let a system overheat.

The same hose also fits the 1975-1976 Ford F-150 V8 5.9L or 6.4L, the 1975-1979 F-150 V8 7.5L, the 1973-1976 Ford F-250 V8 5.9L or 6.4L and the 1973-1979 F-250 V8 7.5L, and each takes one.
