Dayco Radiator Coolant Hose P/N:71977
Dayco 71899 lower radiator coolant hose for the 1997-2003 Ford F-150 V6 4.2L and other vehicles carries coolant between the radiator and the engine. It replaces a lower hose that has cracked, softened or started to seep.
A soft or swollen hose, coolant drips under the front of the truck, or a falling coolant level can mean this hose is wearing out. With the engine off and cool, look over the hose and both ends for cracks, bulges or damp residue before you order, because a weeping clamp or radiator neck can look the same. One lower hose goes on each truck.
This hose fits the 1997-2003 Ford F-150 V6 4.2L and the 2004 Ford F-150 Heritage V6 4.2L.
