What engine coolant should I choose for my car?

Что такое антифриз? Охлаждающая жидкость - это то же самое, что и антифриз?

What is antifreeze? Is coolant the same as antifreeze?

While the terms antifreeze and coolant are often used interchangeably, there is technically a difference. Antifreeze refers to the concentrated glycol based fluid that mixes with the water in your engine’s coolant system to prevent it from freezing up. It also reduces its boiling point and prevents the metal parts of the motor from overheating and corroding.

When diluted with water, the solution is called coolant. Nowadays, it is more common to buy a pre-mixed car engine coolant rather than pure antifreeze. Although this is more convenient than diluting the fluid yourself, you normally end up paying more for less product. Antifreeze will not cool the engine effectively on its own.

What coolant should I use for my car?

First of all, there are three common types of coolant to choose from: Inorganic Additive Technology (IAT), Organic Acid Technology (OAT), and Hybrid Organic Acid Technology (HOAT) coolant. While they all typically have a glycol base, different corrosion inhibitors and additives are used for each type.

Inorganic (IAT) antifreeze, also known as ‘conventional’ coolant, uses phosphate-silicate additives to form a protective barrier over the engine parts made from metals like cast iron, copper and brass. Most older vehicles manufactured before 1998 use this coolant technology. The main downside of IAT formulas is that although they work quickly, they don’t tend to last very long, requiring a replacement every 2 years or so.

Most newer models use OAT formulas. They use organic acids to protect the motor against oxidation, as well as advanced additives. This type is much more efficient than conventional products and has a longer lifespan. However, OAT car antifreeze does not protect copper and brass, which is why it’s incompatible with older vehicles. It should not be mixed with other types as this will cause a blockage in the car cooling system radiator. HOAT coolants are improved products which combine the properties of IAT and OAT fluids.

The simplest way to find the right one for your car’s requirements is to check out the manufacturer’s recommendations in your owner’s manual.

What colour is antifreeze/coolant?

People used to determine the properties and vehicle compatibility of a coolant by its colour. For example, OAT formulas would normally contain an orange dye and Phosphated HOAT antifreeze would be pink or blue. IAT products generally contain a green dye. However, this is no longer a reliable method for picking an antifreeze as colour codes can vary between coolant manufacturers.

How often should I change my car coolant?

The replacement interval for your coolant will depend on the type of coolant and additives used, as well as factors such as the age of the vehicle and your driving habits. The general recommendation for IAT fluid is to change the coolant every two years whereas OAT fluids can last up to five years.
