The answer to the question, “Do I need antifreeze in the summer?” is “no.” Antifreeze is a mixture of water and ethylene glycol (an antifreeze) that protects your car from freezing during cold weather.
Antifreeze also cools the engine by absorbing heat as it changes from liquid to gas, and then releasing it into the air so it doesn’t build up inside your engine.
The amount of antifreeze you put in your car depends on whether you live in a warm or cold climate. In warm climates where temperatures rarely dip below freezing, you may not need any antifreeze at all.
If you live in a cold climate where temperatures consistently drop below freezing during winter months, though, you will need some kind of antifreeze protection in your engine.
