It is engineered specifically to prevent rust and corrosion in cooling system components. This coolant mixes with most extended life antifreezes, reducing the need for a complete system flush. Additionally, it inhibits the buildup of unwanted scale deposits, contributing to improved system cleanliness. By maintaining consistent engine temperature, it supports efficient fuel consumption.
