Mixing antifreeze of different colors and manufacturers. Myths and Realities
Antifreezes are fluids, freezing only at extremely low temperatures. They are commonly used for cooling car engines. In Russia, a substance called Tosol used to be applied for many years as antifreeze. Even now a colloquial name of all antifreezes among many motorists is “Tosol”. Today, two types of antifreeze are used to cool car engines. One of them is based on salts; the other is acid-based. The color of fluid has nothing to do with the classification! Professionals use the classification of G11 and G12 classes. Which one is better? It depends on the materials the engine cooling system of your car is built of.
Why may I not mix antifreezes of different classes?
Every experienced mechanic will tell you, that you may not mix antifreeze of two different classes. However, almost 79% of motorists adhere to another view: you can mix antifreezes and there is nothing terrible in it. This is a mistake. Even fluids of the same color but of different classes contain different additive packages. In fact, YOU CAN mix antifreezes of different colors or different manufacturers but only if they belong to the same class. It is important to remember that a G11 antifreeze can be mixed ONLY with an analogue also labeled G11! The same is with antifreezes labeled G12!
What happens if I mix G11 and G12 antifreezes?
In the process of mixing and multiple warming-cooling cycles this liquid will behave totally unpredictable. Whether the seals would erode, foam would appear, would it cause the corrosion of the aluminum, - God only knows, and apparently, do the daredevils who put such experiments. Based on the above, we conclude: you can only mix antifreezes of the same class, and it doesn't matter what color they are.
What should I do if by accident I added an antifreeze of the other class?
It's best not to tempt fate and go to the service station for complete replacement. Mixing different classes of antifreeze can result in sedimentation in the form of flakes, which clog the radiators and engine cooling system, as well as in shortening of the lifetime of the fluid. In addition, such a mixture completely loses its anti-corrosion properties. Do you need it?
Myths about antifreeze colors
Many motorists have a misunderstanding about the color of antifreeze. The majority of car owners are sure that the color of antifreeze and its properties are two things that are intimately related. The most common myth sounds like:
- Red is the best, lifetime is about 5 years;
- Green is average, lifetime is 3 years;
- Blue is the simplest, and it works for a maximum of 1-2 years.
This is totally wrong.
There is another incorrect assertion that all antifreezes of one shade are the same, and you can mix them. Car owners often buy antifreeze judging by the color of that originally filled in the car. However, manufacturers’ assortment knows no bounds. To expand their product range they create fluids of different colors and shades: red, blue, green and even yellow. Even though they may all have the same composition. And vice versa, two fluids with identical color of different producers may have significant differences in composition and must never be mixed together.
Blue antifreeze glows when exposed to ultraviolet light. Why do we need it?
Let’s open the veil of secrecy. In fact any antifreeze, as well as Tosol is initially colorless. In the manufacturing process these fluids are dyed in different colors to give individuality, as well as to improve their visibility in the reserve tank. Blue dye added to the antifreeze is fluorescent (glows under UV lamp). This is to help you quickly find leaks. The amount of dye added to the fluid is minimal – just a few grams per ton.
Надеюсь, что блог здесь существует не для галочки и кто-нибудь всё-так ответит на мой вопрос.
Промывка радиатора достаточно простая процедура. В любом приличном автосервисе она будет стоить в районе 1000 ~ 1500р и займёт от силы пару часов.
Вы так же можете произвести промывку радиатора Вашего авто самостоятельно! Специально для этого мы опубликовали целую [URL='http://freezante.ru/blog/antifriz/2013/07/09/радиатор.html']статью[/URL], в которой поэтапно описан процесс промывки радиатора.
