Can Red and Green Car Antifreeze Be Mixed?
1 Answers
Red and green car antifreeze cannot be mixed. For antifreeze of different colors, there may be differences in chemical properties and components. Even if the main ingredients are the same, the secondary ingredients may vary, and the formulation ratios can differ. Mixing them can easily lead to chemical reactions, causing hazards such as sedimentation, scaling, and corrosion, thereby affecting the engine's lifespan. How to choose antifreeze: The basic indicators of antifreeze are its freezing point and boiling point. On the market, antifreeze comes in several specifications with freezing points of -15°C, -25°C, -30°C, -40°C, etc. Generally, it is advisable to choose one with a freezing point at least 10°C lower than the lowest temperature in your region. How to determine if antifreeze is low: Observe the antifreeze warning light on the dashboard. If it lights up, it is likely due to low antifreeze levels, though it could also be caused by excessively high cylinder temperatures. Check the antifreeze reservoir. If the fluid level is below the minimum mark (MIN), do not continue driving; add antifreeze promptly. Check the water level markings on the antifreeze tank. The normal antifreeze level should be between the maximum and minimum marks. To determine if antifreeze is low, check the markings. If the antifreeze level is below the minimum mark, it indicates a shortage.
