To keep your car running smoothly year-round and to protect your engine from overheating, you should have its radiator flushed and refilled with fresh antifreeze/coolant according to your manufacturer's recommended schedule.

Over time, antifreeze/coolant wears out and loses its ability to protect your radiator from corrosion. With improper maintenance, corrosion can build up to the point that your radiator no longer protects the engine from overheating. Replacing the antifreeze/coolant restores protection levels for the entire cooling system.
