Is it really necessary to change coolant in the car?
Not changing the coolant timely increases the risk of a car's breakdown. The engine may also get damaged due to a higher temperature, or it may not start at a cold temperature. Moreover, older fluids may result in a buildup of acid. The antifreeze may also get contaminated by scaling or rust. The resistance of the antifreeze to freezing and boiling also reduces with time.
What interval is engine coolant changed at?
The time you should change your car's coolant depends on several factors, such as the make and model of your vehicle, its manufacturing date, your driving style, as well as the place where you have driven your car. Depending on these factors, you may need to change your car's coolant after every 30,000 miles or 50, 000 miles. The vehicle's manufacturer manual may also contain the guidelines regarding when you should have the coolant replaced. The manufacturer may also approve a specific coolant for your car. Generally, vehicles need a coolant service after traveling about 100,000 miles. Older vehicles may require servicing more frequently too.
