Radiators, like most parts in your engine, are made of metal. Over time, antifreeze can degrade. As it degrades, coolant loses its protective qualities, PH levels change, and corrosion sets in. Once the corrosion begins, rust, sludge and scale build up through the entire cooling system, including into the engine.
