  • Delo® XLC Antifreeze/Coolant is a heavy-duty, ethylene glycol based engine coolant which incorporates organic corrosion inhibitor technology called aliphatic carboxylates. Delo XLC is a nitrite, nitrate, borate, phosphate, silicate, and amine free formulation designed to provide maximum protection of the six basic metal alloys found in most heat transfer systems. Delo® XLC products do not contain phosphates or silicates which are known to contribute to hard water scale issues. Delo® XLC promotes maximum water pump seal life by eliminating inorganic corrosion inhibitors. Delo® XLC has a recommended service life of 960,000 kilometers/12,000 hours/ 6 years. This product will not require the addition of SCA’s to achieve its recommended service life. Routine visual inspections, coolant top-off and annual testing are recommended to ensure maximum service life.
