What are the differences between red and green radiator coolant?

[VanReed]

There is no difference between red and green radiator coolant; the colors are simply due to added dyes to distinguish them from other liquids, without any special functional differences. Some brands and manufacturers also use unique colors to make their antifreeze stand out. Below is an expanded introduction to radiator coolant colors: 1. The color of radiator coolant is due to the addition of dyes, primarily to differentiate it from other liquids, with minimal functional differences. However, red and green coolants may have different ingredient ratios and chemical properties, and some brands use specific colors to highlight their product identity. 2. Different colored coolants should not be mixed, as this may cause chemical reactions that affect performance. Radiator coolant typically needs replacement every two years, and regular checks on coolant levels are recommended. If the coolant level falls below the minimum (MIN) mark, it indicates a shortage and should be promptly refilled to between the maximum (MAX) and minimum (MIN) marks.
