Can Coolants of Different Colors Be Mixed Together?

[IvanLee]

Coolants of different colors cannot be mixed. Below is some information about coolants: 1. Introduction: Coolant, also known as antifreeze coolant, is a cooling liquid with antifreeze properties. It prevents the coolant from freezing during cold winter parking, which could otherwise cause the radiator to crack or damage the engine cylinder block or head. 2. Reasons for not mixing: Mixing different additives may lead to chemical reactions, rendering the additives ineffective. This can alter the boiling and freezing points of the coolant, compromise its overall corrosion resistance, and cause issues such as sedimentation, scaling, and corrosion, thereby reducing the coolant's service life.
