Both specialists and drivers emphasize that the concentrate should be diluted with soft distilled water.
This coolant is available in several commercial grades:
- 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 isless, the freezing threshold will be higher. But water when diluted should not be more than 70%, as the solution will lose effectiveness due to the low concentration of additives.
- Coolstream Standard 40. This antifreeze is ready for use and can be used up to -40 degrees. This modification is used for engines of heavy equipment 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 be used, including in harsh 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 elements of the cooling system and engine mechanisms as a whole.
Coolstream NRC 40
