5 questions about antifreeze
Modern internal combustion engines are exposed to high temperature loads, so it is worth taking seriously the choice of coolant. The choice of coolant is recommended to be done according to the instructions of the car manufacturer or service. We've compiled the top 5 most frequently asked questions about antifreeze to help you
How to dilute antifreeze concentrate
The most popular are antifreeze concentrates due to their cost effectiveness. To obtain ready-to-use coolants, it is necessary to add only specially prepared or distilled water to the concentrates. The proportions are always indicated by the manufacturer on the coolant concentrate packaging.
What is the difference in the color of the coolant?
Liquids of the same color can be completely different in composition, while multi-colored ones, on the contrary, can be the same. Color has nothing to do with the chemical composition of coolants.
What are the key parameters for choosing the right antifreeze?
Antifreezes differ in composition, color, packaging. Coolant compositions mainly contain alkylene glycols, mainly ethylene glycol or propylene glycol, as antifreeze component. The composition includes various types of anti-corrosion additives. Engines are increasingly using a variety of materials such as cast iron, copper, brass, soft solder, steel, magnesium and aluminum alloys. Such a variety of materials determines high requirements for the anti-corrosion properties of antifreeze. Pay attention to whether the additives are suitable for your car's cooling system. Any type and any degree of corrosion is a potential risk factor that can shorten the life of an engine and reduce its reliability. Antifreeze must also be compatible with non-metallic components such as elastomers and plastics from hose connections or gaskets and must not alter them. The composition of the coolant is critical for heat transfer in modern combustion engines.
Can I mix different colors of antifreeze?
Antifreeze of different colors can be mixed if the antifreeze compositions are compatible in base and additive packages. If in doubt, you can do a compatibility test of the old and new formulations.
Flushing the system when replacing antifreeze. Do I have to do this? Flushing the system with a complete change of antifreeze is mandatory if:
Flushing the cooling system is not necessary if:
- The newly poured antifreeze is compositionally compatible with the old one.
- Old antifreeze is transparent and does not show any traces of contamination or sediment.
- You are not sure that before filling with new antifreeze, you will be able to completely remove the flush residues from the cooling system. This often happens if you replace the antifreeze yourself (with your own hands).
The specialists of AutoChemie Bitterfeld GmbH place high demands on Silver Wheel brand antifreezes. Silver Wheel Antifreezes provide excellent engine overheating protection. Silver Wheels are manufactured from carefully selected components with the use of additives, the latest world developments. The use of an exclusive additive package effectively prevents problems in the entire cooling system of the vehicle. Parts, especially the pump and radiator, work more efficiently, which significantly increases their resource. Throughout their life, coolants provide excellent protection against corrosion and sludge formation, protecting the radiator and the entire cooling system. That is why the company's coolants are the best combination of base components and exclusive additives created by the professionals of AutoChemie Bitterfeld GmbH.
There is no clear understanding of what exactly was poured into the car earlier.Dirt and deposits are visible in the drained coolant and in the system.You are switching to another type of antifreeze that is not compatible with the previously used one.
