Cooling fluid has an important task: it dissipates heat from the engine and thus protects it from overheating. In order to guarantee reliable cooling in extremely cold conditions during the winter and also in very hot conditions during the summer, the fine channels in the engine block and cooling system must remain free from deposits. This is where the robust and durable OKIYA cooling water filters show their worth: they consistently filter suspended particles and impurities from the cooling fluid. The result is an engine that stays cool under all conditions.
