Mobil Delvac™ Extended Life Coolant/Antifreeze
Providing corrosion protection of all cooling metals
Mobil Delvac Extended Life Coolant/Antifreeze is a phosphate-free, silicate-free, nitrite-free and borate-free, ethylene glycol-based coolant that is designed to provide exceptional wet sleeve liner cavitation and corrosion protection of all cooling system metals.
Mobil Delvac Extended Life Coolant/Antifreeze is formulated with organic corrosion inhibitors to provide total cooling system protection for 1,000,000 miles of on-road use (8 years or 20,000 hours of off-highway use). Since the organic corrosion inhibitors do not readily deplete, Mobil Delvac Extended Life Coolant/Antifreeze eliminates the need for Supplemental Coolant Additives (SCAs) as required when using conventional coolants.
Mobil Delvac™ Extended Life Coolant/Antifreeze is recommended by ExxonMobil for use in:
- All types of heavy-duty diesel, gasoline and natural gas engines
- Stationary engine applications regardless of fuel type being used
- Marine cooling systems where freeze protection is needed
- Mixed fleets where both light-duty and heavy-duty trucks are present
Features and Benefits
• Long Service Life: 1,000,000 miles of on-road use (8 years or 20,000 hours of off-highway use)
• Designed for use in engines running EGR, SCR and ACERT technologies that can increase cooling system temperatures
• Eliminates the cost of SCAs, test strips and manpower required to test the coolant and add SCAs
• Can accept up to 25% mixing with conventional coolant technologies, with no detrimental effect to corrosion protection or reducing the extended life properties
• Fully compatible with other quality Organic Acid (OAT) and Nitrited Organic Acid (NOAT) heavy-duty extended life coolants
• Non-abrasive formula can improve water pump seal life
• Optimal hard water compatibility and reduced hard water scale
• Provides outstanding long-term elastomer compatibility
