The FLEETGUARD Coolant Additive, available in a 5-gallon container, extends engine life by preventing rust and scale buildup in the cooling system. It is formulated to enhance heat transfer and maintain optimal engine temperature. This additive reduces maintenance frequency by minimizing corrosion and deposits, and helps prevent cavitation damage, thereby improving the reliability of engine components. Additionally, it provides long-lasting protection, making it ideal for heavy duty fleet vehicles.
