• A. Increases heat transfer efficiency
• B. Oil contamination
• C. Damage and corrosion
• D. Electrical shorting of sensors

Answer: (C)

Supplemental coolant additives are water-soluble chemicals added to the cooling system to shield metal parts from corrosion and damage. They work by forming a protective film on metal surfaces, buffering and stabilizing pH, and sequestering minerals that could form deposits or promote rust. By reducing the electrochemical reactions that cause corrosion and minimizing wear on components like the radiator, water pump, and heater core, these additives help extend the life of the cooling system. They aren’t primarily aimed at increasing heat transfer efficiency, preventing oil contamination, or addressing electrical shorting of sensors, so their main purpose is protection against damage and corrosion.
