The Best Engine Antifreeze and Coolants in 2021

Winter and freezing temperatures are your car radiator’s worst enemy. It could cause a seize-up effect and seriously affect the car engine, leaving your car unable to operate and needing expensive repairs.

In some extreme cases, you might even have to scrap the car completely. This is why you need a car antifreeze. Antifreeze is often confused with coolant for cars, and there are a lot of similarities between them. But actually, they are not the same thing.

What is Antifreeze?

Car antifreeze is a liquid that is added to the cooling system of your car and stops the water in your car radiator from freezing under normal weather conditions. Antifreeze, which contains propylene glycol as the main antifreeze ingredient, lowers the engine coolant’s freezing point so that it doesn’t freeze at cold temperatures.

It also raises the boiling point of the liquid so that it doesn’t evaporate. The coolant also works to keep the water pump internal parts lubricated so that they all work smoothly. When choosing an engine antifreeze and coolants, one question that many car owners ask is,

What color is Antifreeze?

This question is important because antifreeze comes in several colors; there is red antifreeze, blue antifreeze, pink antifreeze, orange antifreeze, and even green antifreeze. To understand what each color of antifreeze represents, you might need to look at an antifreeze color chart.

Antifreeze vs. coolant

Many people confuse antifreeze with coolant, and admittedly, it’s easy to make that mistake because both liquids are used to keep the car engine cool and prevent overheating. However, antifreeze is more concentrated than coolant and should never be used directly. Antifreeze is mixed with water to make coolant.

Antifreeze is a hazardous liquid, and it is very important to keep your car functioning properly. However, there are many types of antifreeze to choose from, and not all of them are good for your vehicle; for example, cheap antifreeze is less likely to protect your engine than a standard, mid-price antifreeze. You also want to watch out for the antifreeze smell.
