Can green and red car antifreeze be used together?
1 Answers
Different colors of car antifreeze cannot be mixed. For antifreeze of different colors, there may be differences in chemical properties and composition. Even if the main components are the same, the secondary components 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 is available in freezing points of -15°C, -25°C, -30°C, -40°C, etc. Generally, it is advisable to choose one that is 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 liquid level is below the minimum mark (MIN), do not continue driving and promptly add antifreeze. Check the water level markings on the antifreeze tank. The antifreeze level should normally be between the maximum and minimum marks. To determine if antifreeze is low, check the markings. If the antifreeze is below the minimum mark, it indicates a deficiency.
