5 Best Engine Coolants and Antifreeze To Buy – 2017 | ResearchCore

Introduction To The Highest Rated Antifreezes and Coolants

Buying the right antifreeze or coolant for your car engine can be trickier and challenging than you think. There are actually three different types of coolants to choose from, and each is quite different from the other. (We will focus on the types of coolants later on in this guide)

When purchasing engine coolants for your car, it’s important to consider your frequency of flushing out the coolant, the types of additives you prefer in your formula, and other crucial considerations. Before we narrow down to the best coolants for car engines, let’s discuss several things about these additives.

What Is Engine Coolant and How Does Help Your Car?

Engine coolant, also known as anti-freeze is a liquid solution that’s designed to control your car’s engine temperature and taper excess heat to its radiator. It is an auto maintenance product that is consumed by internal combustion engine. However not all coolants can be used on any engine; some engines, especially the newer engine models, requires special formulas that comply with the car regulations.

A couple of years back, all anti-freeze, no matter the brand, were green. This is because it was produced with silicate as its corrosion. The coolant was mixed with water in a ratio of 50-50 and then poured into the car radiator. The antifreeze carried heat to the radiator while the engine operated, thereby preventing freezing as well as protecting the cooling system from rusting. Nowadays, there’re different types of coolants technology, and they come in various colors. They are also being manufactured in an environment-friendly nature and contain less content of propylene glycol (PG).

Types of Engine Coolant

There are three types of antifreeze;

1. IAT or Inorganic Acid Technology

IAT was the first engine coolant and was used from the early 1920s-1990s. It contains silicate and phosphate that serves as the coolants corrosion inhibitor. It’s dyed bright green and sometimes yellow. It should be flushed after every 36,000 miles or after every two years.

2. OAT or Organic Acid Technology

Unlike IAT, this type of coolant doesn’t have silicate and phosphate to inhibit corrosion of engine. Different manufacturers use different chemicals to provide protection against corrosion and rust. It’s also known as Extended Life Coolant or Long Life Coolant because it lasts longer than IAT. However, it’s slightly incompatible with older engines as these engines are made of brass and other metals while OAT is made to protect aluminum- the main metal used to make car engine nowadays. OAT coolants should be replaced after every five years or every 150,000 miles. It comes in different colors, but the typical OAT often comes in shades of orange.

3. HOAT or Hybrid Organic Acid

Just as the name suggests, HOAT is crossover or hybrid between IAT and OAT. It uses silicate and phosphate as corrosion inhibitors, but it also uses OAT additives such as nitrites. It’s compatible with virtually all car engines as it has the components of both OAT and IAT engine coolants. This antifreeze also reduces the proneness to rusting and corrosion in brass, copper, and aluminum. It should be replaced after every five years or every 150,000 miles.

Fundamental Things To Keep In Mind When Using Engine Coolants

Don’t mix types and colors

Your standard green engine coolant typically used in older cars is geared towards preventing corrosion on steel parts, whereas the newer ones are meant for aluminum and other alloys. If you mix the two, cooling will not take place as both can neutralize one another. This can also cause more mess if they turn into a gel and restrict flow.

Follow the ratio

Some coolants are meant to be added to the engine straight out of the bottle, whereas others need to be diluted with water in a ratio of 50-50. Having a mixture that’s too weak or too strong can lead to poor engine cooling.

Water is better than nothing

If your car runs low on coolant, maybe from a leak, and there’s no repair facility or gas station in sight, adding water to it can sometimes help you for short term. However, you need to keep checking the condition of the engine.

The Bottom Line

Choosing the best coolant for your car engine always boils down to the kind of car model you have, the chemical compound you would like to have, and finally how well it will help your engine cooling system. A stable engine will give you peace of mind while on the road and enable your car hit peak performance.
