What is the purpose of the additive within the coolant filters?

The purpose of the additive within the coolant filters is to condition the coolant to minimize build-up. This conditioning helps improve the overall performance and longevity of the coolant by preventing the formation of sludge and deposits that can compromise the cooling system's efficiency. Additives can modify the physical and chemical properties of the coolant, allowing it to remain effective over time even as it encounters various contaminants and environmental factors. By helping to control issues such as corrosion and scaling, the additive ensures that the coolant can circulate effectively within the engine, maintaining optimal thermal management.

While some options describe other functions, such as sediment absorption or suspension, these activities are not the primary purpose of the additives in coolant filters. The focus on conditioning highlights the preventative aspect, which is critical for maintaining a clean and efficient cooling system.
