What is the difference in the color of antifreeze? Can antifreeze of different colors be mixed?

The attentive car owner is sureFindThe color of antifreeze added on different vehicles is different. Can antifreeze of different colors be mixed? What is the difference between them?

The color of the antifreeze represents different components. Common antifreezes include ethylene glycol, propylene glycol and glycerol (also known as "glycerin"). In order to distinguish the components, dyes will be added to adjust the color of the antifreeze.

At present, the antifreeze on the market is mainly based on ethylene glycol. The boiling point of ethylene glycol is high and the freezing point is low.green,The color added to propylene glycol isPink, The color added to glycerol isblue.

Can different colors of antifreeze be mixed?

Can not be mixed.Different colors represent the addition of different types of additives, and their chemical composition is different, and they are prone to chemical reactions when mixed with each other, causing precipitation, scaling and corrosion and other hazards, thereby affecting the service life of the engine. Ethylene glycol and propylene glycol will react under high temperature and pressure to form a gum base, which can cause clogging.

The normal operation of the engine is inseparable from antifreeze, and in addition to the antifreeze function, the antifreeze also has functions such as cooling, anti-scaling, and anti-corrosion. The color of the antifreeze is to inform that it is toxic and distinguish other liquids. When we use it, different colors cannot be mixed. ,Never use tap water instead.
