What happens if coolant is not changed?
The coolant can become more acidic over time and lose its rust-inhibiting properties, causing corrosion. Corrosion can damage the radiator, water pump, thermostat, radiator cap, hoses and other parts of the cooling system, as well as to the vehicle heater system. And that can cause a car engine to overheat.
Is a coolant flush necessary?
Most agree that if you have a new car with less than 10,000 miles on it, there should be no need to do a radiator flush for at least a year. If there are no other signs that you need to flush out your radiator, you should do it at least every 30,000 miles or according to your owner’s manual recommended schedule.

How often should antifreeze be replaced?
every 30,000 milesA typical mechanic will recommend changing coolant every 30,000 miles. But many will tell you, changing the coolant is not even on their radar. An owner’s manual might recommend changing the coolant/antifreeze after the first 60,000 miles, then every 30,000 miles.
Is it OK to add new coolant without draining the old?

Does the color of antifreeze matter?
The truth is, color is not a reliable predictor for what type of coolant you have. For example, OAT coolants are usually orange, yellow, red or purple. HOAT coolants are orange and yellow for the most part. … Coolants that manufacturers sell can confuse matters even more, like Honda’s blue coolant.
