Can Water Be Added to a Car's Radiator?

[Elliott]

Water can be added to a car's radiator. Reasons: Water has a high specific heat capacity, meaning its temperature does not rise significantly after absorbing heat from the engine block. Therefore, the engine's heat is transferred through the liquid cooling circuit using water as the heat carrier. The heat is then dissipated via large-area cooling fins through convection, maintaining the engine's optimal operating temperature. Radiator: A car radiator primarily consists of a radiator core, water pipes, cooling fins, an upper tank, and a lower tank. The upper tank is located on the radiator, connected to the lower tank via water pipes. Hot water flows from the upper to the lower tank, cooling down in the process, while the cooling fins form air channels. Working Principle: The fan's suction and the relative wind speed from the car's forward motion draw large amounts of cold air through the air channels. This air absorbs the heat from the cooling water flowing through the pipes and then releases it into the atmosphere.
