How to Clean a Very Dirty Car Radiator?

[Frank]

To clean a very dirty car radiator, you can use a specialized radiator cleaner designed for automobiles. Pour it into the water circulation system and let it idle for a period to allow the solution to circulate. The car radiator, also known as the heat exchanger, is a key component in the car's cooling system. Its function is to dissipate heat. The coolant absorbs heat in the water jacket, flows to the radiator where the heat is dissipated, and then returns to the water jacket to circulate, achieving temperature regulation. The radiator is a crucial part of a water-cooled engine, serving as a vital component in the engine's cooling circuit. It absorbs heat from the engine block to prevent overheating. Due to water's high specific heat capacity, the temperature rise after absorbing the engine block's heat is not significant. Therefore, the engine's heat is transferred through the liquid cooling circuit, using water as the heat transfer medium. The heat is then dissipated through large cooling fins via convection, maintaining the engine at an optimal operating temperature.
