Coolants and Cooling System Fluids

Coolants and Cooling System Fluids play a critical role in regulating engine temperatures and ensuring long‑term reliability. Engine coolant absorbs and dissipates heat, circulating through the radiator and engine block to maintain an optimal thermal range. A coolant filter removes impurities, extending the life of the fluid and associated components.

Different formulations such as yellow coolant, pink antifreeze, green antifreeze, and red antifreeze are designed for specific engine types and materials, making it vital to select the right fluid for each application. Understanding the difference between antifreeze vs coolant is important for maintenance, as antifreeze is the concentrated additive that, when mixed with water, becomes the coolant in an automobile. Coolant concentrate allows precise mixing to achieve the required protection and performance characteristics, making it a core component in maintaining a stable and efficient cooling system.
