Shell’s Rotella ELC Extended Life Coolant is the subject of a free compact disc that provides “easy-to-follow, step-by-step guidelines” on how to convert a heavy-duty diesel engine’s cooling system from conventional to extended life coolant. 

Once a conversion is completed, cooling-system protection is provided for up to 600,000 miles or 12,000 hours of service. The typical
conversion normally takes less than one hour to perform, Shell says, and it doesn’t require draining and refilling of coolant. Nor will the cooling system ever again need to have supplemental coolant additives (SCAs) added.

The conversion is recommended for use in all North American heavy-duty diesel and natural-gas engines, including Caterpillar, Cummins, Detroit
Diesel, International, Mack, Mercedes, Volvo and others. The primary component is Shell ELC Conversion Fluid, and only one gallon is required to convert a 12-gal cooling system.  It contains a super-concentrated dosage of coolant/antifreeze additives blended in a 50/50 mixture of ethylene glycol and de-ionized water. The 50/50 pre-mixed product has been formulated to have minimal effect on the freeze point of the coolant in use, says Shell, and is fully compatible with all reputable ethylene-glycol-based engine coolants.
