Nitrited Organic Acid Technology (NOAT)

Prestone Command® Heavy Duty Concentrate and 50/50 Antifreeze/Coolant are Nitrite Organic Acid Technology (NOAT) for use and compatible with ANY NOAT Extended Life Heavy Duty antifreeze/coolant in ANY diesel-powered commercial vehicle engine or stationary engine. Its advanced, patented formulation is a concentrated blend of premium long-lasting inhibitors designed to provide up to 750,000 miles/15,000 hours* of protection against temperature extremes, rust, corrosion, scale and premature water pump failure.

*To achieve 750K mile extended service life, follow these steps. Step 1: Perform a cooling system flush and then fill the cooling system with the proper mixture of Prestone Command® Extended Life Concentrate coolant and high quality water. Step 2: As coolant level drops through normal engine use, top up using only Prestone Command® NOAT Extended Life Concentrate prediluted coolant as necessary. Step 3: Test coolant at least twice a year, Spring & Fall, every PM is preferred – use a refractometer to make sure your coolant is adjusted to the correct coolant/water mixture and then use test strips to assess nitrite level, and pH. Add NOAT coolant extender at 300k and 600k and as necessary to maintain inhibitor level and pH. Use new coolant if replacing a cooling system part.
