The use of antifreeze helps prevent engine overheating and premature failure. The presented compositions circulate through the cooling system, after which they enter the vehicle radiator. There, the temperature of the mixtures is reduced due to the directional air flow that occurs during driving. Previously, drivers used ordinary water to cool the motor. But only in winter it froze, which led to deformation of the pipes of the cooling system and the radiator grille. All experienced motorists advise beginners to fill in exclusively special coolants. For example, Dex Cool antifreeze has excellent performance.
For which machines
This coolant is designed specifically for GM vehicles. It is perfectly compatible with Opel, Chevrolet, SAAB, Daewoo car engines.
Production technology
GM Dex Cool antifreeze is made using carboxylate production technology. To protect against corrosive processes, special carboxylic acids are used. Unlike silicate antifreezes,the compositions presented do not create a protective film over the entire surface of the metal parts of the cooling unit. They are extremely directional. That is, these elements prevent the spread of corrosion that has already begun. The advantage of such mixtures is that they do not contain inorganic impurities, such as silicates or phosphates. That is, the probability of solid precipitation on the inner surface of the cooling system is reduced to zero. Antifreeze Dex Cool, made using this technology, is also distinguished by an extended service life.
Appearance
The presented mixture has a red color or any of its shades. There is no fundamental difference in this case.
Type of antifreeze
Dex Cool antifreeze is sold in concentrated form. The initial mixture consists of 95% ethylene glycol, while the remaining 5% is water and various modifying additives. Therefore, before use, this composition must be further diluted with water. The final pour point of the mixture depends on the proportions that the driver chooses. For example, when using equal proportions of antifreeze and water, the final crystallization temperature will be -38 degrees. If you double the proportion of the concentrate, that is, prepare a solution in a ratio of 2 to 1, then the mixture will withstand cooling to -64 degrees.
Mixing rules
The main disadvantage of Dex Cool antifreeze is its incompatibility with ordinary tap water. This liquid is characterized by increased rigidity. The presence of magnesium and calcium ions in the composition of the final mixture can significantly reduce the performance of the composition. Therefore, it is better to use only distilled water for dilution.
Compatible with other formulations
The presented antifreeze is compatible with formulations from other brands made using carboxylate technology. But experts do not recommend mixing these substances with each other. It's just that companies use completely different types of additives in the manufacture of mixtures, which can adversely affect the final performance.
Lifetime
Dex Cool Longlife antifreeze differs from analogues and has an extended service life. The coolant provides reliable engine cooling for 5 years or 250 thousand kilometers.
Reviews
Motorists have an ambiguous opinion about the presented composition. The advantages of drivers include reliable protection of the radiator and other metal elements of the cooling system. As an advantage, the increased service life of the mixture is also indicated. The disadvantages are the high cost of antifreeze and the need to additionally purchase distilled water for mixing.
