Antifreeze is an important part of vehicle maintenance, providing effective engine cooling. Without the correct coolant, the engine can suffer serious damage from overheating in summer or freezing in winter.

In this article we will look at the different types and give advice on proper selection and replacement.

Types of antifreeze by composition

Antifreeze is a chemical compound that not only protects the engine from overheating but also guards against corrosion and freezing. In summer it prevents overheating by carrying heat from the engine to the radiator, while in winter it prevents the fluid from freezing and damaging the engine.

There are two main types depending on composition: monoethylene glycol and propylene glycol. The first is more widely used but is more toxic, while the second is safer for the environment and people, although slightly more expensive.

Types of antifreeze by color

The color of antifreeze is often used to distinguish different types, but it should be noted that it is not an indicator of the quality or chemical composition of the coolant. Here are the types according to color:

1. Blue, yellow or green

   Uses ethylene glycol with inorganic additives. Suitable for older vehicles with a simple cooling system, produced up to 1996. It contains silicates that protect against corrosion but has a shorter life and should be replaced every 2-3 years.

2. Red or pink

   Suitable for more modern cars produced after 1996. It contains organic components such as carboxylates and silicates, provides longer-lasting protection and has better anti-corrosion properties. It is recommended to replace it every 5 years.

3. Purple or violet

   The most modern solution, based on propylene glycol or glycerin, with environmental advantages and high quality. Suitable for cars manufactured after 2008, this type provides the best protection and is safer for the environment.

Antifreeze colors typically reflect the additives used in their composition as well as the technology by which they are produced.

Different antifreeze standards

Antifreezes are also classified according to standards, the most common of which are:

• G11 – traditional, based on monoethylene glycol, suitable for older cars. It is usually recognized by its blue or green color;

• G12 and G12+ – these standards were developed for newer cars and use organic acids for better corrosion protection. G12 is red in color, while G12+ can be violet or pink.

Choosing the right antifreeze is important not only to protect the engine but also to provide long-term efficiency of the cooling system.

How to choose the right antifreeze for your car?

The choice of antifreeze depends on the make and model of your vehicle. It is important to check the owner's manual for the type recommended by the manufacturer. Never mix different types, as this can lead to reduced cooling efficiency and even damage to the cooling system. For example, blue (G11) should never be mixed with red (G12).

The choice of antifreeze should also match local climatic conditions. In a cold climate it is important to protect against freezing, while in a warm climate protection against overheating is a priority.

Additionally, for vehicles used in motorsport or that frequently carry heavy loads, an antifreeze with higher protection and resistance to extreme temperatures is recommended.

Changing antifreeze – when and how?

Changing the antifreeze is an important aspect of vehicle maintenance. It is recommended to be done every 2 to 5 years, depending on the type and manufacturer recommendations. The process includes draining the old fluid, flushing the system with water and then filling with new fluid, usually in a 50:50 ratio with distilled water.

Regularly check the condition of the antifreeze and remember to replace it on time for optimal engine protection.
