Where to Add Radiator Coolant?

[SanAlan]

Radiator coolant should be added into the car's expansion tank. Open the engine hood, locate the expansion tank (usually spherical in shape), remove the tank cap, and pour in the appropriate amount of radiator coolant. The optimal filling level is between the MAX and MIN marks. Additional information: Radiator coolant should not be mixed with water. Adding water will reduce the coolant's effectiveness by lowering its boiling point (diminishing cooling performance) and raising its freezing point (making it prone to freezing in cold climates). Although radiator coolant contains water, it is specially treated deionized soft water. Regular tap water contains various impurities and ions that can form scale over time, leading to blockages.
