What are the key parameters of correct antifreeze fluid selection?
Up-to-date combustion engines are exposed to high temperature loads; for this reason, one should take seriously the coolant selection. It is better to buy a coolant in accordance with the instructions of the vehicle manufacturer.
Antifreeze fluids differ in composition, color, and package. Coolants are mainly composed of alkylen glycols, mostly ethylene glycol or propylene glycol as the antifreeze component. Different types of anticorrosion additives are included. Various materials, such as cast iron, copper, brass, soft solder, steel, and magnesium and aluminium alloys are increasingly used in engines. Such variety of materials is the reason of strict requirements for anticorrosion properties of the antifreeze fluid. Verify whether additives are appropriate for the cooling system of your vehicle. Any type and any degree of corrosion is a potential risk that can reduce the service life and reliability of the engine. These antifreeze fluids must be compatible with non-metallic components, for example, elastomers and plastics used in hose connections or gaskets and must not change them. The coolant composition is critical for heat exchange in up-to-date combustion engines.
