What are the ingredients of coolant

The main components of antifreeze are ethylene glycol, propylene glycol, diethylene glycol, silicates and so on. These mother liquids are mixed with pure soft water in different proportions to form a mixed solution called antifreeze.

Most antifreeze on the market today is green antifreeze, whose base liquid is ethylene glycol.

If it is red with a hint of orange, the main ingredient is propylene glycol. If it is blue antifreeze, the main ingredient is monoglyceride. If it's pink antifreeze, the main ingredient is glycerin.

Antifreeze is essentially transparent, and the color difference is due to the addition of coloring agents.

Antifreeze contains many additives, such as colorants and preservatives. There are different formulas for different colors of antifreeze and additives.

The different chemical components of the additives may react chemically when they are mixed, creating a gelatinous substance. Purpose chemical reaction may also cause other problems, such as precipitation, scaling, corrosion, etc., leading to antifreeze failure, and in serious cases, even affect the engine.

So when you add antifreeze, try not to mix it. If you want to replace the antifreeze, first clean all the previous antifreeze in the car, and then add the new antifreeze.
