Delo® ELC Antifreeze/CoolantProduct Description Delo® ELC Antifreeze/Coolant products are single phase, ethylene glycol based NOAT (Nitrited Organic Additive Technology) products available in various dilutions that are based on patented aliphatic carboxylate corrosion inhibitor technology specifically formulated for heavy duty cooling system applications that require nitrite. Delo ELC Antifreeze/Coolant products deliver value through: • Managing Costs — Helps eliminate the cost of using SCAs (supplemental coolant additives), regular testing and the manpower required to perform these tasks effectively eliminating those costs when compared to conventional or fully formulated coolants. • Long Service Life — Service life of 1,000,000 miles / 1,600,000 km on-road use / 15,000 hours off-highway use, or 8 years, of diesel engine coolant system protection when properly maintained. • Optimal Cooling System Operation — The silicate free formula improves heat transfer when compared to silicate containing formulations. Silicates deposits can reduce heat transfer and increase downtime due to over-heating. • Maximum Hardware Life — Maximum water pump life due to minimal water pump seal wear resulting from the silicate free formulation. • Excellent Protection — Effective, long term corrosion protection, even at elevated temperatures, of commonly found cooling system metals. Effective at protecting aluminum in high temperature applications. • Variable Applications — Recommended for use in on-road, off-road and stationary engine applications that call for an extended life, silicate and phosphate free formulation that contains nitrite and molybdate. Can be used in engines using variable fuel types and variable emission control protocols. Check with your OEM for specific product application requirements. • Compatibility — Compatible with other coolant formulations and supplemental coolant additives. Chevron recommends that this product not be diluted by more than 25% with other coolant formulations. Dilution by more than 25% will reduce extended life performance. • Biodegradability — Biodegradable in its unused form. • Stability — Storage stable for a minimum of 8 years as purchased. Delo ELC Antifreeze/Coolant products are heavy duty engine coolants that use a patented organic corrosion inhibitor technology called aliphatic carboxylates. Delo ELC is free of nitrates, borates, silicates, phosphates and amines. These products contain nitrites and molybdates for additional cylinder liner protection. Delo ELC Antifreeze/Coolant products are recommended for use in a wide variety of cooling system applications including on-road, off-road and stationary engine applications. These products are also recommended in mixed fleet applications where heavy duty and light duty trucks are present. Please check your OEM's coolant recommendations. Delo ELC Antifreeze/Coolant products do not require the addition of supplemental coolant additives to obtain their service life of 1,000,000 miles / 1,600,000 km / 15,000 hours, or 8 years, when properly maintained. Routine visual inspections, coolant top-off and annual laboratory testing are recommended to ensure maximum service life. Delo ELC Antifreeze/Coolant products have been fully tested under the CAT EC-1 specification and have been found to meet all the chemical and performance requirements of this specification. Product(s) manufactured in the USA and Colombia. Always confirm that the product selected is consistent with the original equipment manufacturer's recommendation for the equipment operating conditions and customer's maintenance practices.

• Product concentrates should be agitated before use or dilution. • Delo ELC Antifreeze/Coolant - Premixed 50/50 should be used as purchased. No dilution is recommended. • For maximum protection against freezing in extremely cold areas, a 60 percent solution of Delo ELC Antifreeze/Coolant - Concentrate (3 parts antifreeze/2 parts water) can be used. Concentrations greater than 67 percent are not recommended. • Always dispose of used coolant in accordance with local, state and federal guidelines. Recommended applications for Delo® ELC Antifreeze/ Coolant products: • Heavy duty engines regardless...
