Product Description

Mobil Delvac NOAT Extended Life 50/50 Prediluted Coolant/Antifreeze is a Nitrated Organic Acid Technology (NOAT) ethylene glycol base coolant that is designed to provide exceptional wet sleeve liner cavitation and corrosion protection to all cooling system metals. Mobil Delvac NOAT Extended Life 50/50 Prediluted Coolant/Antifreeze is formulated with organic corrosion inhibitors to provide total cooling system protection for 750,000 miles of on-road use (8 years or 15,000 hours of off-road use) without the use of Supplemental Coolant Additives (SCAs)'. Mobil Delvac NOAT Extended Life Coolant/Antifreeze is phosphate-free, silicate-free and borate-free.


To realize ongoing protection from Mobil Delvac NOAT Extended Life 50/50 Prediluted Coolant/Antifreeze, top off the cooling system, as needed, with either Mobil Delvac NOAT Coolant/Antifreeze Concentrate or Mobil Delvac NOAT 50/50 Prediluted Coolant/Antifreeze which is a 50/50 mix of Mobil Delvac NOAT Coolant/Antifreeze Concentrate and deionized water. Maintain the freeze point in the cooling system between -10F and -62°F.
