The correct selection of coolant is extremely important for ensuring optimal engine operation and durability of the cooling system. Coolant not only dissipates heat, but also prevents corrosion, minimizes scale formation and protects the system from freezing . The decision to select the right fluid should take into account the vehicle manufacturer's specifications, fluid technology and operating conditions.
There are three main coolant technologies available on the market, differing in chemical composition and application:
IAT (Inorganic Additive Technology)
Based on inorganic additives such as silicates and phosphates, these fluids are designed primarily for older vehicles. They protect the metal parts of the system from corrosion, but require more frequent replacement (every 2-3 years).
OAT (Organic Acid Technology)
They use organic corrosion inhibitors, making them more durable and effective in protecting modern cooling systems. Replacement is recommended every 5 years.
HOAT (Hybrid Organic Acid Technology)
A hybrid combination of IAT and OAT technologies. These fluids offer extended corrosion protection and are compatible with both older and modern engines.
The choice of coolant depends on several aspects. First, you should check the specification indicated by the vehicle manufacturer, which includes both the type of fluid and its properties. Second, it is worth considering the operating conditions - in vehicles used in extreme temperatures, fluids with appropriate thermal resistance should be used. It is also worth paying attention to the miscibility of the fluid with other products and its anti-corrosion properties to avoid problems with the cooling system.
Even the best coolant loses its properties over time . Regular replacement, according to the vehicle manufacturer's recommendations, prevents corrosion, scale formation and a decrease in cooling efficiency. Symptoms of fluid wear may include changes in color, the presence of deposits or frequent problems with engine overheating. It is also worth remembering that mixing different types of fluids can lead to undesirable chemical reactions and damage to the cooling system.
Correct selection and regular replacement of coolant is the foundation of efficient engine and cooling system operation. Using products in accordance with the vehicle manufacturer's recommendations and avoiding mistakes such as mixing different fluids will significantly extend the life of these systems.
