Coolant systems need to be flushed because the coolant fluid, antifreeze, will break down over time. It will also collect rust and dirt particles which can get stuck in your heater core and/or radiator. If your radiator gets clogged it will cause your car to overheat. If your heater core gets clogged you won't have any heat in your car. You should follow your owners manual to see how often you should have your antifreeze changed. General guidance suggests that you should change the antifreeze around 100,000 miles and every 3 years after to maintain your car's life.
