Dayco Radiator Coolant Hose P/N:70622
Dayco 72744 upper radiator coolant hose for the 2009-2016 BMW Z4 6-cylinder 3.0L and other vehicles carries coolant between the engine and the radiator.
Coolant stains near the hose ends, a cracked or swollen hose, or a collapsed section can mean this hose is worn, though a loose clamp or the radiator neck can be behind the same signs. If the hose is the cause, this one replaces it.
As an upper coolant hose, it fits the 2009-2016 BMW Z4 6-cylinder 3.0L, the 2013-2015 BMW X1 6-cylinder 3.0L and the 2007-2013 BMW 335i, and each of these cars takes one.
