Today’s modern cooling systems are made from aluminum. This allows for a lighter cooling system as well as better heat transfer. These modern cooling systems are assembled using a form of brazing called CAB. This process allows for the smallest most efficient seams allowable, also increasing the efficiency of the cooling system. The one drawback with these systems is the fact that some coolant additives will react and possibly corrode the metals in them. To prevent this, Chevron has created Chevron Delo XLC Antifreeze/Coolant. This modern coolant protects today’s modern aluminum systems by preventing pitting and degradation.
Delo XLC Antifreeze/Coolant is a heavy-duty, ethylene glycol-based engine coolant which incorporates patented organic corrosion inhibitor technology called aliphatic carboxylates. The Delo XLC formula is free of nitrite, nitrate, borate, phosphate, silicate, and amines. It 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 1,000,000 miles / 1,600,000 km / 15,000 hours or 8 years. This product will not require the addition of supplemental coolant additives (SCAs) to achieve its recommended service life.
Routine visual inspections, coolant top-off, and annual laboratory 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.
Recommended uses include:
- Heavy-duty engines regardless of fuel type or environmental controls being used where the OEM recommends a nitrite free, silicate free coolant
- Mixed fleets where automobiles, light-duty trucks, and heavy-duty trucks are being serviced and the OEM recommends a nitrite free, silicate free product
- Recreational vehicles where a nitrite free, silicate free product is recommended
- On-road, off-road, and marine cooling system applications.
