Antifreeze does two jobs, and most people only think about one. It keeps the coolant from freezing inside the engine on the coldest nights, and it protects the radiator, water pump and heater core from corrosion the rest of the year. Over time it breaks down and loses that protection, even when the reservoir still looks full. A quick test shows how cold yours is protected to. If it's worn out, a coolant flush replaces it with the type your vehicle was built for, before the first hard freeze. Call 405-350-1951.
