3 Popular Brands of Car Antifreeze: what should I pour into the cooling system?

Antifreeze, or coolant, is a component no less important for a car than engine oil or fuel. Its task is to remove excess heat from the engine, preventing overheating in summer, and not to freeze at low temperatures in winter, protecting the cooling system from damage. Choosing high–quality antifreeze is the key to long and trouble-free engine operation.
The market offers a huge number of coolants of different colors, standards and manufacturers. It can be difficult to understand this diversity. However, there are brands that have earned the trust of car owners and automakers due to their consistent quality and proven effectiveness. Let's look at three popular brands of antifreeze often found on store shelves.
Coolstream: the Russian quality standard
Coolstream is one of the leading Russian manufacturers of antifreeze, whose products are used for primary filling on the conveyors of many car factories operating in Russia (for example, Ford, Renault, Nissan, AvtoVAZ). This in itself indicates a high level of trust and compliance with the strict requirements of automakers.
The company offers a wide range of coolants created using modern carboxylate (OAT) and iridium (Si-OAT) technologies. They provide effective protection against corrosion, cavitation and overheating, and have a long service life (up to 5 years or 250,000 km). Popular products:
- Coolstream Premium. Carboxylate antifreeze (G12+), often recommended for Renault, Nissan, and AvtoVAZ vehicles.
- Coolstream Optima. A low-cost carboxylate option for many foreign cars and domestic cars.

Coolstream has established itself as a reliable manufacturer of high-quality coolants at a reasonable price.
Felix: the energy of protection
Another popular Russian brand is Felix, owned by Tosol-Sintez. Felix antifreeze is also widely available on the market and is in demand by car owners. The company actively promotes its products, emphasizing the use of high-quality basic components and additive packages.
Felix offers various types of antifreeze, including traditional (silicate), hybrid and carboxylate (OAT). This allows you to select the coolant for almost any car, both new and used. The range includes:

Sintec: accessibility and versatility
Sintec is another major player in the Russian coolant market, manufactured by Obninskorgsintez. Sintec products are known for their availability and wide distribution in auto parts stores across the country.
The brand offers both traditional antifreeze and modern antifreeze of various classes (G11, G12, G12+). This makes Sintec a universal choice for a wide range of cars, from domestic classics to modern foreign cars. Although Sintec is often positioned as a more budget-friendly option, the company claims that its products meet the necessary quality standards and GOST standards. Popular products:
- Sintec Unlimited (G12++). The latest generation of hybrid antifreeze.
- Sintec Premium (G12+). Carboxylate antifreeze.
- Sintec Euro (G11). Hybrid antifreeze.
- Sintec antifreeze. Traditional coolant for older car models.
Sintec is the choice for those who are looking for an inexpensive but workable coolant.
The choice is yours, but wisely.
Coolstream, Felix, Sintec are just three examples of popular antifreeze brands on the Russian market. There are other worthy manufacturers, both domestic and foreign (for example, AGA, Lukoil, Mobil, Castrol, Liqui Moly).
When choosing an antifreeze, it is more important to focus not so much on the brand or color of the liquid, but on the recommendations of your car's manufacturer (indicated in the service book) and the type of antifreeze (G11, G12, G12+, G12++, G13). It is not recommended to mix antifreeze of different types and manufacturers, as this may lead to deterioration of their properties and damage to the cooling system. It is better to completely replace the old coolant with a new one that meets the tolerances of your car. Download local apps from melbet russia for Android and iOS.
