Are Red and Green Antifreeze the Same?
1 Answers
Red and green antifreeze are not the same. Antifreeze containing glycerol appears red in color; if it contains ethylene glycol, the color is green; and if the color is blue, the component is propylene glycol. The primary function of antifreeze is to prevent the freezing of vehicle fluids under low-temperature conditions. Additionally, antifreeze helps prevent the aging and rusting of vehicle components. During cold winters, antifreeze ensures that the fluids do not freeze, making it easier to start the car. In summer, even though temperatures rise, antifreeze remains essential to prevent potential engine damage such as cylinder seizure.
