In the cooling system of a heavy vehicle, what is the main function of the radiator?

Question

DentroTest · Accepted Answer

The radiator is a fundamental heat exchanger in the liquid cooling circuit. The coolant absorbs the heat generated by combustion and friction as it circulates around the cylinders and then reaches the radiator, where it passes through fine cells and ducts exposed to the flow of outside air (with the help of the fan), dissipates the heat and lowers its temperature before returning to the engine. That is why its job cannot be to increase the engine temperature: the radiator dissipates heat, it does not supply it. Nor is it its job to prevent evaporation or leakage of the fluid: leaktightness depends on the closed design of the circuit, the hoses and the valve cap of the expansion tank, not on the radiator.
