Does Adding the Wrong Color of Car Antifreeze Have Any Impact?

[AlexanderMarie]

Adding the wrong color of car antifreeze does have an impact. Antifreeze of different colors performs differently in terms of properties. Mixing antifreeze of different colors can easily lead to chemical reactions, and in severe cases, the antifreeze may become ineffective. If you want to switch to a different color of antifreeze, you need to completely drain the existing antifreeze, clean the car's cooling system, and then add the new antifreeze. Even in summer, antifreeze should be used, and water should not be used as a substitute. Car antifreeze, also known as coolant, is designed to allow the car to continue operating in low winter temperatures. Engine coolant contains substances that lower the freezing point of water, acting as antifreeze to prevent the cooling system from freezing in cold weather.
