The Shell Rotella Extended Life Coolant-Nitrite Free (ELC-NF) protects aluminum components, including modern brazed aluminum heat exchangers, and it meets many on- and off-highway engine specifications. The formulation may be used for commercial fleets, passenger cars and light duty trucks. The coolant extends life operation in medium and heavy duty diesel, gasoline, LNG and natural gas vehicles, engines, water pumps, radiators and other cooling system components by reducing water-pump failures, hard-water-scale deposits and silicate gel. It is compatible with other extended-life coolants, and no supplemental coolant additives are required. The coolant is designed to go 600,000 on-highway miles or 12,000 hours in commercial applications.
