Delo XLC Antifreeze/Coolant is a heavy-duty, ethylene glycol based engine coolant which incorporates patented organic corrosion inhibitor technology called aliphatic carboxylates. Delo XLC is a nitrite, nitrate, borate, phosphate, silicate, and amine- free formulation that provides 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.
Note: These products are not to be used to protect the inside of potable water systems against freezing.
