Antifreeze concentrate dilution calculator
Why buy concentrate and how to prepare it?
Buying concentrate is often more profitable than ready-made antifreeze, especially if you need a large volume for a truck or special equipment. When servicing heavy machines, it is important to use only high-quality components. If you need spare parts, always choose trusted suppliers, for example https://kamaz.org.ru/magazin/zapchasti/sistema-okhlazhdeniya/ to avoid fakes that can destroy the radiator from the inside.
The main myth of beginners: “the more concentrate, the better the protection.” This is wrong. Pure ethylene glycol freezes already at -13°C. Only when mixed with water does it acquire its unique properties - the ability not to freeze down to -40°C or even -65°C.
🧪 Distillate is the base
Never use tap water. The salts and minerals in it will instantly react with antifreeze additives, forming scale that will “clog” the thin radiator channels.
📏 Accurate to the gram
Use our calculator so you don't have to guess by eye. A little too much water will raise the freezing point, and at -30°C the liquid will turn to mush, bursting the pipes.
The paradox of concentrate
If you pour 100% concentrate without water into the tank, it will freeze in the first light frost. Maximum protection is achieved with a 2:1 ratio (66% concentrate), which allows it to withstand down to -65°C. The best option for the middle zone is a 1:1 ratio (up to -37°C).
Instructions for using the calculator
To get an accurate result, you need to know only two parameters: the total volume of your cooling system (indicated in the car manual) and the target temperature you want to achieve. Our tool will calculate the number of liters of concentrate and water that need to be mixed.
Table: Proportions and freezing temperatures
| Concentrate (%) | Water (%) | Crystallization onset temperature |
|---|---|---|
| 33% | 67% | -18°C |
| 40% | 60% | -25°C |
| 50% | 50% | -37°C (Gold Standard) |
| 60% | 40% | -52°C |
Frequently asked questions (FAQ)
Is it possible to mix antifreeze of different colors?
You can’t focus only on color. Важен состав присадков (G11, G12, G12++). Mixing different types may result in sedimentation and pump failure.
How to check the density of the finished mixture?
For this, a hydrometer device is used. If after dilution you doubt the result, measure the density: for a mixture of -37°C it should be around 1.070 g/cm³.
