What to Do If Coolant Is Mixed?

[EmilyDella]

If coolant is mixed, it should be replaced immediately, and the same type of antifreeze should be added separately. The following explains why coolant should not be mixed: 1. Different brands and colors of coolant have different components such as corrosion inhibitors and rust removers. Their chemical compositions vary, and mixing them can lead to chemical reactions, which may not only fail to provide anti-corrosion and anti-scale effects but also cause adverse consequences. 2. Coolants are divided into three types based on their ingredients: ethanol, ethylene glycol, and glycerol. Their boiling points and freezing points differ, so car owners should choose the appropriate coolant according to their vehicle's needs, rather than adding it randomly or mixing different types.
