Can Green and Red Antifreeze Be Used Together?

[VanJackson]

Green and red antifreeze cannot be mixed. Different colored antifreeze may have varying chemical properties and compositions. Even if the main ingredients are the same, the secondary components and formulation ratios can differ. Mixing them can lead to chemical reactions, causing hazards such as sedimentation, scaling, and corrosion, which can affect the engine's lifespan. How to choose antifreeze: The basic indicators of antifreeze are its freezing and boiling points. The market offers antifreeze with freezing points of -15°C, -25°C, -30°C, and -40°C. Generally, it's 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: Check the antifreeze warning light on the dashboard. If it lights up, it likely indicates low antifreeze levels, though it could also be due to excessively high cylinder temperatures. Inspect the antifreeze reservoir. If the level is below the minimum mark (MIN), do not continue driving; add antifreeze promptly. Check the water level markings on the antifreeze tank. The antifreeze level should normally be between the maximum and minimum marks. If it's below the minimum mark, it indicates a shortage of antifreeze.
