Dayco Radiator Coolant Hose P/N:70539
Dayco 72302 lower radiator coolant hose for the 2003-2009 Toyota 4Runner V8 4.7L and other vehicles carries engine coolant between the radiator and the engine. Replacing a worn hose helps the cooling system hold its coolant.
Coolant dripping from the hose, a hose that looks cracked or swollen, or an engine that runs hot can mean the lower hose is failing. A leaking radiator, a weak water pump or a loose clamp can be behind the same signs, so find the cause before buying a hose.
This is a direct-fit replacement for the 2003-2009 Toyota 4Runner V8 4.7L and the 2003-2009 Lexus GX470.
