This article presents an analysis of the evolution of internal combustion engine (ICE) cooling systems and examines the impact of thermal conditions on their service life and reliability. Particular attention is paid to the negative consequences of thermal imbalances. The main causes of thermal imbalances, associated with increased loads and cooling system malfunctions, are analyzed. It is shown that engine overheating leads to deterioration of lubrication conditions, increased mechanical stress, and accelerated wear of key components. The paper also examines the operating principles of electronic thermostats and electric pumps, their advantages (precise control, reduced fuel consumption), and their disadvantages associated with complex design, high cost, and difficult diagnostics. The important role of the cooling system in ensuring a stable engine thermal condition is highlighted.
