The most important component of the cooling module is the radiator which is designed to dissipate the heat absorbed by the coolant from various components (engine, EGR cooler, etc.) to the ambient air. It consists of a core and coolant tanks with all requisite connections and fastening elements. The radiator core is usually made of aluminum, while the coolant tanks are made either of aluminum—just like the core—or fiber glass-reinforced polyamide.
