Types of Coolant

Over the years there have been many different types of ANTIFREEZE/COOLANT developed. Below is a list of the most common types.

  • LOW SILICATE GREEN / IAT (Inorganic Additive Technology)"Traditional Green" antifreeze was used by manufacturers until 2002. This formula uses silicate and phosphate corrosion inhibitors to protect the metal parts of the engine and cooling system. IAT coolants should not remain in a car longer than two years or 30,000 miles or per the manufacturer's recommendation.

  • OAT (Organic Acid Technology)These coolants typically do not use silicate corrosion inhibitors. It is strongly recommended that you use newer technology coolants designed for today's cars and light duty trucks. OAT coolants have a longer projected service life and should be flushed at least every 5 years or 150,000 miles or per the manufacturer's recommendation.

    Shop OAT Coolant

  • HOAT (Hybrid Organic Acid Technology)These coolants contain different additives when compared to OAT, but also contains some silicate. Ford, Chrysler, and some European vehicles used HOAT coolant in the past. Ford was dyed yellow and Chrysler's was dyed orange (but chemically different then DEX-COOL). Commonly, U.S. car manufacturers have recommended flushing HOAT coolant and replacing with OAT.
