EXTENDED LIFE ANTIFREEZE/COOLANT

Prestone Command® Heavy Duty Nitrite Free Extended Life and 50/50 Antifreeze/Coolant are Organic Acid Technology (OAT) for use and compatible with ANY OAT 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 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® Nitrite Free coolant and high quality water. Step 2: As coolant level drops through normal engine use, top up using only Prestone Command® Nitrite Free 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 contamination (nitrite contamination can occur when adding a Nitrite Organic Acid Technology (NOAT) to a OAT), and test pH. Use new coolant if replacing a cooling system part.
