It is made from blue silicone reinforced with polyester fabric plies, designed to transfer coolant between the engine, radiator, and heater core in heavy-duty trucks. Silicone construction handles extreme temperatures continuously from -65°F to +350°F and resists ozone and oil splash far better than standard rubber hoses. Since radiator hoses degrade over time from heat cycling and coolant chemicals, this hose is commonly replaced during cooling system overhauls, engine rebuilds, or when a blown hose causes a roadside leak.
