Dayco Radiator Coolant Hose P/N:72989
Dayco 72301 radiator coolant hose for the 2003-2009 Toyota 4Runner V8 4.7L and other vehicles carries engine coolant between the radiator and the engine.
A soft, bulging or cracked hose, coolant drips or a coolant level that keeps dropping can mean a radiator hose is wearing out. A leaking radiator, a weak radiator cap, a failing water pump or a stuck thermostat can also sit behind coolant loss or overheating, so find the cause before you buy. This listing is one hose, and each vehicle needs one.
It fits the 2003-2009 Toyota 4Runner V8 4.7L, the 2003-2009 Lexus GX470 and the 1965-1966 Buick Electra V8 6.6L or 7.0L.
