What You Need to Know About Your Car’s Coolant

Antifreeze, also known as coolant, is a bright liquid made of propylene glycol or ethylene glycol that mixes with water in your vehicle. Contrary to popular misconception, antifreeze isn’t just important during the winter: this liquid keeps your radiator from overheating or freezing in extreme temperatures. Coolant is responsible for keeping your car moving on a 115-degree summer day or on sub-zero winter nights.

When antifreeze is mixed with water in your radiator, it raises the boiling point of the water from 212 degrees Fahrenheit to 223 degrees Fahrenheit to protect your car during intense summer days. During the winter, the freezing point of water in your radiator is reduced from 32 degrees Fahrenheit to -35 degrees Fahrenheit. Antifreeze is needed year-round to protect your car from damage and keep the radiator working as efficiently as possible.

Should Antifreeze Be Changed Seasonally?

Over time, your radiator develops a build-up of debris that can clog your cooling system. Your coolant levels can also drop over time, especially in severe climates or with extreme driving. While it’s not necessary to change your coolant with the seasons, it is important to keep an eye on coolant levels and have the system flushed occasionally to make sure the mixture of water and antifreeze remains around 50:50.
Most types of antifreeze need to be flushed and replaced every two years or 30,000 miles. If you’re due for a coolant flush, contact Quanz Auto Body today for this and other important vehicle maintenance!
