Dayco Radiator Coolant Hose P/N:70539
Dayco 71028 upper radiator coolant hose for the 1980-1981 Chevrolet Malibu V8 5.7L, the 1980-1982 Malibu V8 4.4L, the 1980-1983 Malibu V8 5.0L and other vehicles carries hot coolant from the engine to the radiator.
Coolant stains at the hose ends, a cracked or swollen hose and soft spots can all mean the hose is wearing out. They can also come from a loose clamp or another leak, so with the engine off and cool, look over the hose and its connections and find where the coolant is actually escaping before you replace anything.
It also fits the 1982-1992 Chevrolet Camaro V8 5.0L and the 1982-1992 Pontiac Firebird V8 5.0L, and each of those takes one hose. If your car is not named here, open the "Vehicles it fits" section and check your exact model and engine.
