Do new cars need water added to the radiator?

New cars do not require water to be added to the radiator, but it should be checked frequently. Typically, new cars do not need coolant added to the radiator, and if necessary, only antifreeze should be added. The car radiator, also known as the heat exchanger, is a key component in the car's cooling system. Radiators can be installed in three methods: same-side inlet and outlet, opposite-side inlet and outlet, or bottom inlet and outlet. Regardless of the installation method, the number of pipe fittings should be minimized. Car antifreeze serves multiple functions including cooling, antifreeze, anti-boil, anti-rust, and anti-scale. After use, it forms a protective film on metal surfaces, comprehensively protecting the engine, radiator, water pump, and pipes made of various materials from corrosion. This ensures the normal operation of the engine, effectively improves heat dissipation, and extends the service life of the engine and rubber components.
