This picture shows you what happens to metal heater hoses when exposed to the elements over a period of time. The heater hose carries antifreeze to the heater core. The heater core is what gives your vehicle nice toasty heat in the winter. The antifreeze leak can also cause your vehicle to overheat as well. So keep an eye on it. Have it checked the next time you see your mechanic.
