Mobil Delvac™ Extended Life Coolant/Antifreeze

Providing corrosion protection of all cooling metals

Mobil Delvac™ extended life prediluted coolant antifreeze

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
