Where do we use an SI engine
Antifreeze - you should know that
The engine is the most important part of your vehicle. Antifreeze for your cooling system is essential to ensure that it is also protected in winter at low temperatures.
Without radiator antifreeze, your cooling water runs the risk of freezing at sub-zero temperatures. If that is the case, two dangers are only a matter of time: Either you suffer total engine damage due to overheating of the engine or the frozen coolant causes the radiator and engine to burst.
The antifreeze not only regulates the temperature of the cooling water, but also prevents corrosion and deposits. In addition, the antifreeze acts as a lubricant for the individual parts in the cooling circuit such as the thermostat or water pump. The glycol component not only lowers the freezing temperature of the cooling water, but also increases the boiling point. This prevents the engine from overheating in summer. For these reasons, we recommend using radiator antifreeze not only in winter, but also on warmer days.
Antifreeze: there are these types
Not all antifreeze agents are created equal. A distinction can be made between three different types of radiator antifreeze, which differ in their chemical composition:
This antifreeze is the oldest of the three types. It consists of ethylene glycol, water and corrosion inhibitors (silicates). As we have already explained to you, antifreeze should not only protect against the cold. With this antifreeze, the silicates also act as a quickly reactive corrosion protection and are compatible with a particularly large number of vehicle models. This antifreeze is usually green or blue in color.
Our Elaskon antifreeze falls under this type and is blue in color.
In the case of antifreeze agents with Organic Acid Technology (OAT), silicates are not used. In order to protect against corrosion, the manufacturer uses organic acids. OAT antifreeze is not recommended for older vehicles with an aluminum radiator. This antifreeze is usually red or purple in color.
- Hybrid OAT antifreeze
Hybrid OAT or Si-OAT antifreeze are a combination of the previous types. Radiator antifreeze with silicates protects better against corrosion than OAT agents, but must be replaced more frequently. Hybrid OAT antifreeze combine both advantages and thus protect against corrosion for a particularly long time and have a long service life.
Which radiator antifreeze do you need?
Depending on the make of the car and the year of manufacture, it is decided which antifreeze you need. Before buying a radiator antifreeze, check your manual to find out which type you need. It does not list the name of the original product from your vehicle manufacturer, but also whether it is a product with or without silicate and what color it is. With this information you can buy your own coolant in order to avoid expensive original products from your manufacturer.
In addition, the color of the antifreeze in your cooling system provides information about which agent you need. There are European standards with regard to properties and colors, but no legally binding regulations. Please note that this can lead to manufacturer-dependent differences in the color scheme.
Mixing radiator antifreeze: find the right ratio
The antifreeze changes depending on the mix ratio of antifreeze and water. In the following table we show you at which mixing ratio you have frost protection up to which temperature. The values are based on our ANF antifreeze. In order to enjoy optimal corrosion protection, the proportion of antifreeze should not fall below 33.3%.

-20 ° C
-40 ° C
In our experience, the 1: 1 mixture is the ideal ratio. We do not recommend a higher dosage of antifreeze, as this can reduce the cooling performance. Before mixing your antifreeze, check whether it is a concentrate or a mixture that has already been mixed with water.
Mixing windscreen antifreeze: find the right ratio
Especially on colder days, you should also use a windscreen antifreeze. This prevents the windshield wipers and spray nozzles from freezing. Are you wondering at which mixing ratio of our windscreen antifreeze and water you are protected at which temperatures? We tell you:

What should be considered when using it?
Please only add antifreeze to your cooling system if you have the relevant knowledge. If you see a low coolant level, you have a good opportunity to add antifreeze. However, this may only be done when the engine has cooled down completely.
If it is a concentrate, it must be mixed with water in a suitable ratio. Agents of different types must not be mixed with one another under any circumstances. A hybrid antifreeze should generally be changed at least every three years, and silicate-free agents about every four years.
