modernjäähdytysneste

Modern coolant, known in Finnish as modernjäähdytysneste, refers to the advanced formulations of heat-transfer fluids used in automotive engines and other cooling systems. Unlike older types that primarily relied on ethylene glycol or propylene glycol with simple inhibitors, modern coolants incorporate a complex blend of organic and inorganic additives. These additives are designed to provide superior protection against corrosion, cavitation, and scaling in a wider range of materials found in contemporary engines, such as aluminum, cast iron, and plastics.

The primary function of coolant is to absorb heat generated by the engine and dissipate it through the radiator. Modern formulations offer improved thermal conductivity and a wider operating temperature range, preventing both overheating in hot conditions and freezing in cold climates. They also contain specific agents to lubricate the water pump and seal surfaces, extending component life.

Different types of modern coolants exist, often categorized by their inhibitor technology. These include OAT (Organic Acid Technology), HOAT (Hybrid Organic Acid Technology), and P-HOAT (Phosphate Hybrid Organic Acid Technology). Each offers a specific balance of protection and longevity, with OAT and HOAT generally providing longer service intervals compared to older technologies. Selecting the correct type of modernjäähdytysneste is crucial for optimal engine performance and durability, as using the wrong formulation can lead to premature component failure and reduced cooling efficiency. Always consult the vehicle manufacturer's recommendations for the appropriate coolant type.
