Antifreeze Coolstream: brands, specifications, reviews

In the modern market of auto chemicals, there are so many companies producing antifreezes that the choice is not always simple. One of the popular compounds is Coolstream antifreeze, which will be devoted to this material.

Modern materials without harmful additives

Antifreezes of this brand are related to the products of the new generation. In what way is this expressed? First and foremost in the technology of production: it is based on a dihydric alcohol of ethylene glycol with additives of organic carboxylate acids. Products Coolstream, which is presented in the domestic market, is created on the basis of the concentrate of the Belgian brand Havoline XSC. Unlike many other types of coolant, Coolstream antifreeze does not contain any harmful impurities in the form of borates, phosphates, nitrites, which harm the engine itself and the environment.

Main advantages

Coolstream antifreezes are universal technical liquids, since they can be used on both 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;
• Possibility of combining with plastic and any elastic materials.

But Coolstream antifreeze Premium brand (red color) is completely incompatible with other coolants. In addition, according to many buyers, the products of this brand are too expensive, especially the high cost of premium versions of the liquid. But the quality, functionality with this fluid is not comparable to any antifreeze. We offer an overview of the most popular means of this brand.

Standard

This brand of antifreeze is of high quality due to the lack of harmful substances and the presence of a package of additives. Thanks to them, Coolstream Standard effectively protects the cooling system from corrosion, overheating and hypothermia, boiling. The product is resistant to hard water, it is inexpensive and compatible with the materials of the seals. That is, it does not affect the rubber and polyurethane products of the car in any way. Both specialists and drivers emphasize the fact that dilute the concentrate with soft, distilled water.

The main varieties

This coolant is available in several product varieties:

1. Cool Stream Standard C. It is a coolant concentrate that is diluted with water. The freezing point is -37 degrees. Dilute the antifreeze with water in a ratio of 50 to 50. If the proportion of antifreeze is less, the freezing threshold will become higher. But the water at dilution should not be more than 70%, since the solution will lose its effectiveness due to the low concentration of additives.
2. 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 heavy-duty engines of large volume. The manufacturer recommends the use of this variety on cars GAZ, VAZ, "Kia".
3. Cool Stream Standard 65. This fluid has all the important characteristics, but the freezing threshold is -65 degrees. Such a tool can be used, including in severe climatic conditions.

All three modifications do not contain phosphates and silicates in their composition and are characterized by high stability of the inhibitors. This minimizes the risk of damage to the components of the cooling system and engine mechanisms in general.

Coolstream NRC 40

This liquid based on Havoline concentrate was developed specifically for Renault-Nissan certification engines. And it is this compound that is used to fuel many Renault models in production. The peculiarity of this yellow antifreeze is that it can be used on the entire engine life cycle, without having to change it.

Antifreeze of this variety is of high quality, easy to use and ready for use without dilution. Coolstream NRC 40 is produced on the basis of modern technologies and 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 fluid characteristics fully meet the declared characteristics.

Coolstream Optima 40

This is a standard red antifreeze, which is created based on monoethylene glycol and carboxylic organic acids. The resource is 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 it. According to reviews, this liquid can be successfully used on passenger cars of economy class.

Antifreeze Coolstream Optima is a new generation of fluids and can be used in any cooling system. Unlike most other compounds of similar design, there are no potentially dangerous additives - nitrites, amines, therefore, the environment is practically not harmed. Testing showed that the antifreeze shows all the declared characteristics during the tests.

Application Features

Antifreeze Coolstream Optima begins to crystallize at a temperature of -42 degrees. The fractional composition of the agent is good, as is the temperature of the beginning of the distillation. The product has a low alkalinity, which indicates the use of additives with carboxylic acids in the base. According to reviews, the composition is ideal for refueling such cars as Renault Duster, Lada Largus, Nissan Almera. Drivers emphasize that it is possible to fill this antifreeze and for a long time forget about the cooling system and the engine.

Optima is Coolstream antifreeze (green), which not only conforms to existing norms and standards, but also has the tolerances of leading automotive manufacturers. The green color of the liquid indicates that you can fill the car for at least 3 years. But the color of the antifreeze does not actually play any role, since it is only needed to improve the visibility of the liquid level in the tank and to determine the leakage.

Premium

Coolstream Premium is a universal coolant of orange color. The basis of the product is ethylene glycol and carboxylate technology. There are no harmful substances in the form of silicates, phosphates or nitrates. About this fluid is a lot of good reviews due to its versatility: it is effective in any vehicle. In addition, it can be poured on 250 000 km of run. In this case, you can not worry about the state of the cooling system, even if the car is operated under severe conditions. The quality of the liquid is also evidenced by the fact that it is used for the initial refueling of such cars 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 formation and cavitation. According to reviews, this tool can be used as much as the car itself. And for the achievement of this effect, a package of corrosion inhibitors responds . Car owners note the following advantages of using this type of antifreeze:

• Increased service life, which is ensured by a synergistic composition of the additive package;
• Improved heat transfer, which opens more opportunities for engine designers;
• Reduction of the 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 has received good reviews for the ecological cleanliness of additives, which are based on a patented technology without the use of silicates. In addition, such an efficient package serves as a reliable engine protection against corrosion, with all metal elements. This antifreeze has been approved by manufacturers such as Ford, MAN, Daimler-Chrysler, Hyundai, MTU, KAMAZ, AVTOVAZ. Testing showed that the composition ideally behaves in any tests, showing a crystallization temperature of -40.5 degrees.

conclusions

Coolstream antifreeze is a modern and high quality coolant. Thanks to a balanced and proven composition it can be used on different cars. And the most important advantage of this tool is that it has the tolerances of many leading car manufacturers.

According to users, Coolstream antifreeze is ideal for operation in our country. At an affordable cost, liquids meet all the requirements of norms and standards. And most importantly - they ensure the working capacity of the cooling system for a long time.

When buying a coolant, experts recommend paying attention not to color and compliance with GOSTs, but on the availability of tolerances of various automobile manufacturers. This alone serves as a guarantee of the effectiveness of the application of a specific antifreeze in vehicles.
