They make it easier to compare products directly and allow me to choose wisely rather than just picking the first product off the shelf. This means I not only guarantee the best possible protection for my engine, but also an optimal price-performance ratio.

FAQ

Why is antifreeze essential for the engine?

Radiator antifreeze is essential because it prevents the coolant in the engine from freezing, which can cause damage to the engine and radiator. It also ensures effective heat dissipation from the engine and protects against corrosion and deposits in the cooling system.

How does antifreeze protect the cooling system in winter?

Antifreeze contains ingredients such as ethylene glycol, which lower the freezing point of the radiator fluid and thus ensure that the cooling system remains functional even at sub-zero temperatures and that no damage is caused by ice formation.

How do I find the best antifreeze for my car?

The best antifreeze for your car depends on the manufacturer's specifications, which you can find in your vehicle's owner's manual. Independent reviews, customer reviews and price comparisons can also be helpful in choosing a product that is high quality and reasonably priced.

What features and areas of application are there for the different types of frost protection?

The main types of radiator antifreeze are Hybrid, OAT (Organic Acid Technology) and Si-OAT (Silicated Organic Acid Technology). Hybrid types combine organic and inorganic additives, while OAT uses only organic and Si-OAT uses a mixture of both. Each type has a different duration of effectiveness and is suitable for different vehicle models based on manufacturer recommendations.

How long does radiator antifreeze last and when should I change it?

The lifespan of radiator antifreeze varies depending on the type: Hybrid products should be changed approximately every two years, while OAT products should be changed less frequently. Check the manufacturer's recommendations for your vehicle to find out the exact change intervals.

Why should you consider ecological radiator antifreeze?

Ecological antifreezes are less harmful to the environment because they are often less toxic or biodegradable Use ingredients. For environmentally conscious drivers, they are an alternative that simultaneously protects the engine and reduces environmental impact.

How is the correct mixing ratio of radiator antifreeze determined?

Most manufacturers recommend a 50:50 to 60:40 antifreeze to water ratio. A correct ratio ensures optimal protection against freezing and overheating as well as the efficiency of heat dissipation of the engine.

What is the difference between antifreeze concentrates and ready-made mixes?

Concentrates must be mixed with water and are suitable for users who want to determine the mixing ratio themselves. Ready-made mixes are ready to use and provide convenience as no additional steps are required for mixing.

What do the color codes mean for radiator antifreeze?

The Colors like blue, Green or Red help identify different types of radiator antifreeze. They represent different chemical compositions and should not be mixed to avoid chemical reactions and incompatibilities in the cooling system.

What should I pay attention to when choosing radiator antifreeze in terms of chemical composition?

Make sure the antifreeze is compatible with your cooling system and contains the appropriate corrosion inhibitors. Ingredients like ethylene glycol lower the freezing point, while eco-friendly alternatives are less harmful to the environment.

How do I properly check and top up radiator antifreeze?

To check radiator antifreeze, you can use a measuring spindle. When refilling, you should follow the manufacturer's prescribed ratio of antifreeze to water and ensure that the engine has cooled before opening the cooling system.

Why are independent test reports important when selecting radiator antifreeze?

Independent test reports, such as those from ADAC, offer objective assessments of the performance, quality and price-performance ratio of various radiator antifreeze products. They are a reliable source for finding the right product for your vehicle.
