Dayco 71840 upper radiator coolant hose for the 1996-2007 Ford Taurus and other vehicles carries coolant between the engine and the radiator.
A hose that is cracked, soft, swollen or leaking at the ends can mean it is due for replacement; look it over with the engine off and cool. Coolant loss or overheating alone does not prove the hose is the problem, since a weak radiator cap can cause them too.
This hose fits the 1996-2007 Ford Taurus and the 1996-2005 Mercury Sable V6 3.0L. Each takes one upper hose.
