There are so many antifreeze manufacturing companies on the modern car chemistry market that the choice is not always simple. One of the most popular formulations is Coolstream antifreeze, to which this material will be devoted.
Modern materials without harmful additives
Antifreezes of this brand are a new generation of products. How is this expressed? First of all, in production technology: it is based on the dihydric alcohol of ethylene glycol with the addition of organic carboxylate acids. Coolstream products, which are presented on the domestic market, are created on the basis of concentrate from the Belgian brand Havoline XSC. Unlike many other types of coolants , Coolstream antifreeze does not contain any harmful impurities in the form of borates, phosphates, nitrites, which harm both the engine itself and the environment.
Main advantages
Coolstream brand antifreezes are universal technical fluids, as they can be used on gasoline and diesel engines of any volume and power. These compositions differ:
- high-temperature protection of aluminum parts of the engine cooling system;
- increased service life of the engine water pump;
- increased protection of engine mechanisms from active cavitation;
- the possibility of combining with plastic and any elastic materials.
But Premium Premium Coolstream antifreeze (red) is completely incompatible with other coolants. In addition, according to many buyers, the products of this brand are too expensive, the premium versions of the liquid are especially expensive. But in quality, functionality, not a single antifreeze can be compared with this liquid. We offer an overview of the most popular products of this brand.
Standard
This brand of antifreeze is of high quality due to the absence of harmful substances in the composition and the presence of an additive package. Thanks to them, Coolstream Standard effectively protects the cooling system from corrosion, overheating and overcooling, boiling. The tool is resistant to hard water, is inexpensive and compatible with seal materials. That is, it does not in any way affect the rubber and polyurethane products of the car. Both specialists and drivers emphasize that dilute the concentrate with soft distilled water.
Main varieties
This coolant is available in several product variations:
- Cool Stream Standard C. This is a coolant concentrate that is diluted with water. The freezing temperature is -37 degrees. It is necessary to dilute antifreeze with water in a ratio of 50 to 50. If the proportion of antifreeze is less, then the freezing threshold will become higher. But water at dilution should not be more than 70%, since the solution will lose effectiveness due to the low concentration of additives.
- Coolstream Standard 40. This antifreeze is already ready for operation and can be operated up to a temperature of - 40 degrees. This modification is used for engines of heavy machinery of large volume. The manufacturer recommends the use of this variety on GAZ, VAZ, Kia cars.
- Cool Stream Standard 65. This liquid has all the important characteristics, but the freezing threshold is -65 degrees. Such a tool can also be used in harsh climatic conditions.
All three modifications do not contain phosphates and silicates and are characterized by high stability of the inhibitors. This minimizes the risks of damage to the elements of the cooling system and engine mechanisms in general.
Coolstream NRC 40
This fluid based on Havoline concentrate was developed specifically for Renault-Nissan certification engines. And it is this composition that is used to refuel many Renault models in production. The peculiarity of this yellow antifreeze is that you can use it for the entire operational life of the engine, without having to change it.
Antifreeze of this variety is of high quality, ease of use and is ready for use without dilution. Coolstream NRC 40 is made on the basis of modern technologies and high-quality raw materials with additives in the form of an effective additive package. The liquid begins to crystallize at a temperature of -40 degrees. All liquid indicators fully meet the declared characteristics.
Coolstream Optima 40
This is a standard red antifreeze, which is created on the basis of monoethylene glycol and carboxylic organic acids. Resource - 75,000 km. The liquid can be used on cars of domestic and foreign production. This antifreeze is the most economical option, but its quality does not suffer from this. According to reviews, this liquid can be successfully used on economy class cars.
Coolstream Optima antifreeze belongs to liquids of new generation and can be used in any cooling systems. Unlike most other formulations for this purpose, there are no potentially dangerous additives - nitrites, amines, so the environment is practically not harmful. Testing showed that antifreeze shows all the declared characteristics during the tests.
Application features
Coolstream Optima antifreeze begins to crystallize at a temperature of -42 degrees. The fractional composition of the product is good, as well as the temperature of the start of distillation. The tool has a low alkalinity, which indicates the use in the manufacture of additives with carboxylic acids in the base. According to reviews, the composition is ideal for refueling cars such as Renault Duster, Lada Largus, Nissan Almera. Drivers focus on the fact that you can fill this antifreeze and forget about the cooling system and engine for a long time.
Optima is Coolstream antifreeze (green), which not only complies with existing norms and standards, but also has approvals from leading automotive manufacturers. The green color of the liquid indicates that you can refuel the car for at least 3 years. But the color of antifreeze actually does not play any role, since it is needed only to improve the visibility of the liquid level in the tank and to determine leakage.
Premium
Coolstream Premium is a versatile orange coolant. The product is based on ethylene glycol and carboxylate technology. There are no harmful substances in the form of silicates, phosphates or nitrates. There are a lot of good reviews about this fluid due to its versatility: it is effective in any vehicle. In addition, you can fill it with 250,000 km. In this case, you can not worry about the condition of the cooling system, even if the car is operated in difficult conditions. The quality of the liquid is also evidenced by the fact that it is used for the initial refueling of cars such as Ford, Volvo, Opel, Chevrolet.
Coolstream Premium is a universal protection of the cooling system and the engine of the car against freezing, corrosion, foam and cavitation. According to reviews, this tool can be used as much as the car itself. And for achieving this effect, a package of corrosion inhibitors is responsible . Car owners note the following advantages of using this type of antifreeze:
- extended service life, which is ensured by the synergistic composition of the additive package;
- improved heat transfer, which opens up more opportunities for engine designers;
- reduction of terms for repair of the thermostat, radiator, water pump;
- reliability of operation of the entire cooling system;
- stability and resistance to hard water.
This Coolstream antifreeze received good reviews also for the environmental friendliness of additives, which are based on proprietary technology without the use of silicates. In addition, such an effective package serves as a reliable protection of the engine against corrosion, and of all metal elements. This antifreeze has received approvals from manufacturers such as Ford, MAN, Daimler-Chrysler, Hyundai, MTU, KAMAZ, AvtoVAZ. Testing showed that the composition behaves ideally in any tests, showing a crystallization temperature of -40.5 degrees.
findings
Coolstream antifreeze is a modern and high-quality coolant. Thanks to its balanced and proven composition, it can be used on different cars. And the most important advantage of this tool is that it has the approvals of many leading car manufacturers.
According to users, Coolstream antifreeze is ideal for use in our country. At an affordable cost, fluids meet all the requirements of norms and standards. And most importantly - they ensure the performance of the cooling system for a long time.
When buying coolant, experts recommend paying attention not to color and compliance with GOSTs, but to the availability of approvals from various automotive manufacturers. Only this serves as a guarantee of the effectiveness of specific antifreeze in vehicles.
