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.
