Typical in almost all automotive cooling systems is the eventual formation of rust, scale or other corrosion by-products. Even the slightest build-up of these materials on heat transfer surfaces can drastically affect the engine’s ability to shed heat and thus, decrease the overall effectiveness of the cooling system. Rust, oil and scale build-up will also restrict the flow of coolant through the system, causing overheating and possible engine damage.

Over time, the protective additives in an engine coolant become depleted, thus rendering the coolant acidic and incapable of protecting the components in the system. This results in damaging corrosion in the formation of rust, scale and other debris that prevent proper engine temperature regulation. Left untreated, this condition may cause leaks, overheating, and, if left unchecked, drivability problems.
